Health is a journey that needs careful navigation. When people have low blood counts, finding the cause is key before treatment starts. Medical professionals often see it as a symptom, not a single disease.
Myelophthisic anemia is different because it’s a hypoproliferative disorder. It happens when abnormal tissue takes over healthy bone marrow, stopping blood cell production. Knowing this helps doctors tell it apart from other issues like nutritional problems or chronic inflammation.
Understanding these details is important for better patient care. We use tests like peripheral blood smears, marrow biopsies, and reticulocyte counts to guide our treatment. This method helps us handle complex blood disorders more effectively.
Key Takeaways
- Anemia is a sign, not a single disease.
- Myelophthisic anemia is caused by abnormal cells in the marrow.
- Accurate diagnosis needs blood smears and marrow biopsies.
- Knowing the cause is key to successful treatment.
- Finding the root cause of marrow problems helps patients in the long run.
What Myelophthisic Anemia Means and How It Develops
The bone marrow is like a factory that makes our blood. But what if it gets too crowded? This is called myelophthisis. It happens when normal marrow space is taken over by abnormal tissue or cells.
This crowding makes it hard for the body to make enough red and white blood cells, and platelets. This is the main problem with myelophthisic anemia. It can be caused by many health issues.
Definition of Myelophthisis and the Myelophthisic Process
At its core, myelophthisis is about the bone marrow being crowded out. This can be due to cancer, fibrosis, or other diseases. It makes the marrow less able to make blood.
This leads to a decrease in the marrow’s ability to make blood. Using the term myelopthisis helps doctors understand the problem. It’s not a lack of materials, but a lack of space.
How Bone Marrow Replacement Causes Hypoproliferative Anemia
When the marrow is crowded, it can’t make enough red blood cells. This causes hypoproliferative anemia. The marrow can’t keep up with the body’s need for blood.
The marrow tries to make up for it by releasing immature cells. But this doesn’t work well. It’s an attempt to keep vital organs getting enough oxygen.
Why Myelophthisic Anemia Is Also Called a Leukoerythroblastic Anemia Pattern
The term leukoerythroblastic describes a specific type of blood cell. You’ll see immature white and red blood cells in the blood. This is a key sign for doctors.
This pattern shows that the bone marrow is not working right. It means the marrow is disturbed, pushing these cells into the blood.
| Infiltration Type | Primary Mechanism | Clinical Impact |
| Myelofibrosis | Scar tissue replaces marrow | Severe marrow crowding |
| Metastatic Cancer | Tumor cells occupy space | Disrupted cell production |
| Granulomatous Disease | Inflammatory clusters form | Reduced hematopoietic niche |
How Myelophthisic Anemia Differs From Typical Anemia Categories
Understanding blood disorders is complex. We need to know the difference between marrow issues and other causes of low blood counts. This helps us figure out if the problem is with production, loss, or destruction of red blood cells.
By making these distinctions, we can spot a myelophthisic process more easily. This method helps us not miss serious conditions that need special treatment.
Production Problems, Blood Loss, and Red Blood Cell Destruction
We use the reticulocyte production index to categorize anemia. A number below 2 usually means the bone marrow isn’t making enough new red blood cells.
Nutritional deficiencies or chronic inflammation can also cause low production. But they’re different from conditions where the marrow space is taken up. Blood loss or hemolysis usually leads to higher production and more reticulocytes.
Why the Bone Marrow Is Central to This Comparison
The bone marrow is key for making blood cells. In many anemias, it lacks the necessary materials like iron or vitamins.
But in a myelophthisic process, the marrow is blocked by tumors, fibrosis, or infections. Even with enough iron and nutrients, it can’t work because of the blockage.
How Severity, Cause, and Blood Cell Findings Shape the Diagnosis
Diagnosing anemia involves looking at the patient’s history, CBC results, and peripheral smear findings. We look for signs like teardrop-shaped cells or immature blood cells, which show marrow stress.
The table below shows how different anemia types work:
| Anemia Category | Primary Mechanism | Marrow Status | Reticulocyte Response |
| Hypoproliferative Anemia | Reduced production | Often crowded or depleted | Low |
| Blood Loss | External depletion | Hyperactive | High |
| Hemolytic Anemia | Cell destruction | Hyperactive | High |
| Nutritional Deficiency | Lack of raw materials | Ineffective | Low |
What Are the Differences Between Myelophthisic Anemia and Other Types of Anemia
Many anemias share similar symptoms, but myelophthisic anemia has a unique cause. It’s not just about a lack of nutrients. Instead, it’s about the bone marrow being pushed out by abnormal tissue.
Differences in the Underlying Mechanism
The main difference is in the bone marrow. In most anemias, the marrow is healthy but can’t make enough red blood cells. But in myelophthisic anemia, the marrow is crowded out by things like cancer or fibrosis.
This crowding stops the marrow from working right. It’s like a blockage that prevents healthy blood cells from being made. This is different from the problems seen in anemia caused by lack of iron or vitamins.
Differences in Red Blood Cell Size and Production Response
People with this condition usually have red blood cells of normal size. But, the marrow’s problems can make it release immature cells too early.”The diagnostic challenge of marrow-infiltrating disorders lies in their ability to mimic other conditions while presenting with distinct, often subtle, morphological markers in the peripheral blood.”
— Clinical Hematology Review
Differences in Peripheral Blood Smear Findings
A key sign of myelophthisic anemia is a special pattern in the blood. You might see teardrop-shaped red blood cells and immature white blood cells. This pattern is rare in common anemias.
These signs show that the bone marrow is under stress. The early release of these cells is because the marrow is crowded or damaged.
Differences in Symptoms and Associated Signs
While all anemias can cause fatigue and shortness of breath, myelophthisic anemia often has other signs. You might have a big spleen, bone pain, or unexplained weight loss. These are not common in simple iron deficiency.
| Anemia Type | Primary Mechanism | Smear Findings | Key Clinical Sign |
| Myelophthisic | Marrow Infiltration | Teardrop cells | Splenomegaly |
| Iron Deficiency | Nutrient Lack | Microcytic cells | Pica/Brittle nails |
| Hemolytic | Cell Destruction | Reticulocytosis | Jaundice |
| Aplastic | Stem Cell Failure | Pancytopenia | Infection risk |
These differences help doctors figure out what’s causing your anemia. By knowing these differences, we can find a treatment that works best for you.
Myelophthisic Anemia vs Iron-Deficiency Anemia
Distinguishing between iron-deficiency anemia and myelophthisic anemia needs a close look at blood cell shapes. Both have low hemoglobin, but they start from different places. One is from not enough iron, the other from bone marrow issues.
How Iron Deficiency Impairs Hemoglobin Production
Iron is key for making hemoglobin, which carries oxygen in red blood cells. Without enough iron, your body can’t make enough healthy red blood cells. This leads to less oxygen being carried around your body.
Myelophthisic anemia, on the other hand, happens when healthy marrow is pushed out by abnormal cells. This stops the marrow from sending out new cells into the blood.
Microcytosis and Hypochromia Compared With a Leukoerythroblastic Smear
Iron deficiency shows up as small, pale red blood cells. These cells are small and pale because they don’t have enough iron. This is seen under a microscope.
Myelophthisic anemia, though, shows immature red and white blood cells in the blood. This is different from iron deficiency, which just changes the size of the cells. It shows the bone marrow is badly affected.
Contrasting Complete Blood Count and Iron Study Results
Iron studies show if you’re lacking iron. Low ferritin and iron levels mean your body needs more. This is clear evidence of iron deficiency.
In marrow issues, iron levels might be normal or high because of inflammation. The complete blood count shows different cell sizes. We use these clues to figure out what’s wrong.
Common Causes and Risk Factors for Each Condition
Iron deficiency often comes from losing too much blood, like heavy periods or ulcers. These problems can be fixed with supplements and stopping the bleeding.
Myelophthisic anemia, though, is linked to serious diseases like cancer or bone marrow problems. Because the causes are so different, it’s important to test accurately for your health.
| Feature | Iron-Deficiency Anemia | Myelophthisic Anemia |
| Primary Cause | Nutritional/Blood Loss | Marrow Infiltration |
| Cell Size | Microcytic | Usually Normocytic |
| Iron Studies | Low Ferritin/Iron | Often Normal/High |
| Smear Findings | Hypochromic Cells | Leukoerythroblastic |
Myelophthisic Anemia vs Vitamin B12 and Folate Deficiency Anemia
Both marrow infiltration and nutrient deficiencies cause anemia, but they have different causes. To tell them apart, we need to look at how blood cells are made in the body.
Why B12 and Folate Deficiency Causes Megaloblastic Anemia
Without enough vitamin B12 or folate, the body can’t make DNA right. This stops red blood cells from growing up properly. This leads to megaloblastic anemia.
This is different from marrow infiltration, where the marrow is filled with abnormal cells. Nutrient deficiencies mean the body can’t make the right parts for cell growth. So, the marrow makes big, but not good, cells that often die before they can get into the blood.
Macrocytosis, Hypersegmented Neutrophils, and Other Distinguishing Findings
Macrocytosis is a sign of nutrient deficiency, showing up as big red blood cells. Marrow infiltration, on the other hand, shows immature cells and nucleated red blood cells.
We check for hypersegmented neutrophils in the blood to spot folate deficiency anemia or vitamin B12 deficiency anemia. These cells are a clear sign of DNA trouble, not seen in marrow problems.
Neurologic Features That Suggest Vitamin B12 Deficiency
Vitamin B12 deficiency affects the nervous system, unlike marrow issues. It can cause numbness, tingling, and balance problems.
Some people might also have trouble thinking or feeling things. These symptoms point to a nutritional problem, not a marrow issue.
How Serum Testing Separates Nutrient Deficiency From Marrow Infiltration
When it’s hard to tell what’s causing anemia, we use special tests. We check B12 and folate levels first.
We also look at methylmalonic acid and homocysteine levels. If these are high, it means the vitamins are low. If not, we look at the bone marrow. A bone marrow biopsy can show if there’s a problem with the marrow itself.
Myelophthisic Anemia vs Aplastic Anemia
Understanding the difference between marrow replacement and failure is key in treating blood diseases. Both conditions can lead to hypoproliferative anemia, but they have different causes. Knowing these differences helps us choose the best treatment for our patients.
Bone Marrow Failure Without Marrow Replacement
Aplastic anemia is when the bone marrow fails to make blood cells. The marrow is too empty to produce enough blood components. Unlike other diseases, it’s not filled with abnormal cells or scar tissue; it’s just empty or fatty.
Pancytopenia in Aplastic Anemia Compared With the Leukoerythroblastic Pattern
People with aplastic anemia have low levels of all blood cells. Myelophthisic anemia, on the other hand, shows a leukoerythroblastic pattern. This means there are immature blood cells in the blood because the marrow is disrupted.
How Bone Marrow Biopsy Findings Distinguish the Two Conditions
A bone marrow biopsy is the best way to tell myelofibrosis vs aplastic anemia apart. In aplastic anemia, the biopsy shows fewer blood-making cells and more fat. Myelophthisic anemia, by contrast, has foreign cells like cancer or fibrosis that take over the marrow.
Differences in Causes, Including Medications, Toxins, Infections, and Immune Injury
The causes of these conditions are quite different. Aplastic anemia often comes from the immune system, toxins, viruses, or drug reactions. Myelophthisic anemia is usually caused by cancer, fibrosis, or chronic inflammation that scatters the marrow.
| Feature | Aplastic Anemia | Myelophthisic Anemia |
| Marrow Cellularity | Hypocellular (Empty) | Infiltrated or Fibrotic |
| Primary Mechanism | Stem-cell failure | Space-occupying lesion |
| Peripheral Smear | Usually normal morphology | Leukoerythroblastic |
| Common Causes | Immune, Toxins, Drugs | Cancer, Fibrosis, Infection |
Myelophthisic Anemia vs Anemia of Chronic Disease and Inflammation
Distinguishing between a blockage in the bone marrow and systemic inflammation is key. Both lead to hypoproliferative anaemia, but the causes are different. One is a physical blockage, while the other is a complex signaling issue that limits iron.
Functional Iron Restriction in Chronic Inflammation
In anemia of inflammation, the body reacts to chronic illness by making more hepcidin. This hormone traps iron in storage cells, like macrophages. As a result, the bone marrow can’t get the iron it needs to make new red blood cells, leading to functional iron deficiency.
This is different from marrow infiltration, where the production factory is physically damaged. Instead, the body hides its iron stores to prevent pathogens from using them. This inadvertently starves the red blood cell production line.
Typical Ferritin, Transferrin, and Reticulocyte Patterns
Laboratory tests are key to differentiating these conditions. In anemia of chronic disease, ferritin levels are often elevated or normal, showing iron stores are present but inaccessible. Transferrin levels are low, and the reticulocyte count is inappropriately low given the anemia.
This contrasts with marrow-infiltrating disorders. In these, the bone marrow releases immature cells into the blood, a rare occurrence in simple inflammatory states. We rely on these specific markers to guide our diagnosis.
When Chronic Disease Anemia Becomes Difficult to Separate From Marrow Disease
Diagnostic confusion can occur when a patient has both chronic inflammation and possible marrow involvement. Inflammatory markers like C-reactive protein are elevated in both, making them unreliable differentiators. We must examine the peripheral blood smear for signs of leukoerythroblastosis, indicating physical marrow disruption.
How Inflammatory Disorders and Malignancy Can Overlap With Myelophthisis
Inflammatory disorders and malignancy can overlap with myelophthisis. For example, a patient with metastatic cancer may have both systemic inflammation and direct bone marrow infiltration. In such cases, a bone marrow biopsy is needed to confirm whether the anemia is functional or if the marrow architecture is compromised.
| Feature | Anemia of Chronic Disease | Myelophthisic Anemia |
| Primary Mechanism | Functional iron restriction | Physical marrow replacement |
| Ferritin Levels | Normal or Elevated | Variable |
| Peripheral Smear | Usually normal | Leukoerythroblastic |
| Bone Marrow | Normal architecture | Infiltrated or fibrotic |
Myelophthisic Anemia vs Hemolytic Anemia
Understanding the difference between these two anemias is key. They both cause anemia but in different ways. This means they need different treatments.
Reduced Red Blood Cell Survival Compared With Impaired Marrow Production
Hemolytic anemia is when red blood cells die too early. Your bone marrow tries to make more, but it can’t keep up.
Myelophthisic anemia happens when the bone marrow is crowded or damaged. This stops it from making enough blood cells. It’s a problem of not enough production, not too much destruction.
Reticulocytosis, Elevated Lactate Dehydrogenase, and Low Haptoglobin
Reticulocytosis is when immature red blood cells enter the blood. It shows the marrow is trying to replace lost cells.
Tests show more lactate dehydrogenase and low haptoglobin levels. These signs point to cell breakdown.
Jaundice, Dark Urine, and Splenomegaly as Hemolysis Clues
Jaundice, dark urine, and an enlarged spleen hint at hemolysis. These signs come from broken-down red blood cells.
An enlarged spleen can also mean marrow problems. But with reticulocytosis and low haptoglobin, it usually means hemolysis.
How the Peripheral Smear Helps Identify Hemolysis or Marrow Infiltration
A peripheral blood smear shows what’s happening in your blood. In hemolytic anemia, it might show broken cells.
For myelophthisic anemia, it shows teardrop cells and immature cells. This, along with lactate dehydrogenase levels, helps figure out the cause.
Myelophthisic Anemia vs Thalassemia and Other Inherited Microcytic Anemias
It’s important to know the difference between acquired marrow disease and inherited hemoglobin disorders. Both can change blood counts, but they start in different ways. One is caused by replacing healthy marrow, the other by a genetic problem with hemoglobin.
Genetic Hemoglobin Disorders and Lifelong Microcytosis
Thalassemia is caused by a genetic problem with globin chain synthesis. It’s different from myelophthisic processes, which can be caused by cancer or fibrosis. People with thalassemia often have small red blood cells their whole life.
This is a key sign of an inherited microcytic anemia. In contrast, marrow infiltration can get worse over time. Knowing this helps doctors tell if it’s a long-term genetic issue or a new, serious problem.
Contrasting Red Blood Cell Counts, Cell Size, and Hemoglobin Patterns
Lab tests are key in telling these two apart. In thalassemia, the red blood cell count might be normal or even high, even though the cells are small. This is different from marrow-infiltrating diseases, where red cell production often goes down.Both conditions can show abnormal red cell shapes, but they need different treatments. This makes diagnosis tricky.
— Clinical Hematology Perspectives
How Hemoglobin Electrophoresis Supports a Thalassemia Diagnosis
When someone has microcytic anemia, we use special tests to find the cause. Hemoglobin electrophoresis is the best test for thalassemia. It separates different hemoglobins to show if there’s a genetic problem.
- Hemoglobin Electrophoresis: Finds specific globin chain imbalances.
- Genetic Testing: Confirms mutations.
- Family History: Shows similar blood issues in relatives.
When Splenomegaly and Abnormal Smears Create Diagnostic Confusion
Both conditions can cause an enlarged spleen, or splenomegaly. They can also show similar things on a blood smear. Without a good medical history, it can be hard to tell them apart.
We need to be careful when checking these patients. A lifelong microcytosis usually means an inherited microcytic anemia. But a sudden change in blood counts might mean something more serious. By using advanced tests and looking at the patient’s history, we make sure they get the right treatment.
Myelophthisic Anemia vs Acute Blood Loss and Chronic Blood Loss
When patients have low red blood cell counts, we must figure out why. It’s not just about losing blood; it’s also about how the body makes new cells. Myelophthisic anemia is a hypoproliferative anaemia caused by bone marrow being replaced. Blood loss, on the other hand, is when cells are physically removed from the body.
Timing of Symptoms and Changes in Hemoglobin
In acute blood loss anemia, the hemoglobin might seem fine right after the loss. This is because the body loses both red blood cells and plasma at the same time. But, over 24 to 72 hours, the body tries to fix this by moving fluids back into the blood. This makes the remaining red cells thinner and lowers the hemoglobin.
Reticulocyte Responses After Blood Loss
A healthy bone marrow makes more red blood cells when it loses them. This is shown by an increase in reticulocytes, young red blood cells. But, a marrow affected by disease can’t do this, leading to a lack of new cells when the body needs them most.”The diagnostic challenge lies in identifying whether the marrow is capable of responding to the stress of anemia or if it is structurally compromised by an underlying disease process.”
— Clinical Hematology Perspectives
Laboratory Clues to Ongoing Gastrointestinal or Gynecologic Bleeding
Finding where the blood loss is coming from is key. We check for gastrointestinal bleeding with stool tests and scopes. For women with heavy periods, a detailed gynecologic history is also important.
How Chronic Blood Loss Can Progress to Iron-Deficiency Anemia
Slow blood loss over time can use up the body’s iron. This turns it into chronic blood loss anemia, which is often caused by iron deficiency. Unlike diseases affecting the marrow, this condition can be fixed by stopping the bleeding.
| Condition | Primary Mechanism | Marrow Response | Key Diagnostic Marker |
| Acute Blood Loss | Volume depletion | Increased reticulocytes | Hemoglobin drop after fluid shift |
| Chronic Blood Loss | Iron depletion | Variable | Low ferritin levels |
| Myelophthisic Anemia | Marrow replacement | Inadequate/Absent | Leukoerythroblastic smear |
Diagnostic Clues That Point Toward a Myelophthisic Process
We look for specific patterns in your blood smear to find a myelophthisic process. When the bone marrow is disrupted, it can’t release healthy blood cells. This creates a unique sign that helps us spot this condition.
Leukoerythroblastosis on the Complete Blood Count and Smear
A key finding is a leukoerythroblastic pattern. This means immature red and white blood cells are in your blood. Normally, these cells stay in the marrow until they’re ready.
This pattern shows the marrow is under stress. It means space-occupying lesions are pushing cells out too early. This is a big warning sign for us to check your bone marrow health.
Teardrop Cells, Nucleated Red Blood Cells, and Immature Myeloid Cells
We also look at the shapes and types of cells in your blood. You might see these signs in your lab reports:
- Teardrop cells (dacrocytes): These happen when red blood cells are squeezed in a fibrotic marrow.
- Nucleated red blood cells: These are young red cells without a nucleus, showing the body’s effort to fight anemia.
- Immature myeloid cells: Seeing early-stage white blood cells points to a problem in their maturation.
Bone Marrow Aspiration, Biopsy, and Fibrosis Assessment
While blood tests are helpful, a direct look at the marrow is needed for a diagnosis. We do a bone marrow aspiration and biopsy to see the tissue. This lets us check for scarring or fibrosis.”The bone marrow biopsy remains the gold standard for identifying the infiltration of abnormal cells, whether they are malignant or related to chronic inflammatory processes.”
Imaging and Testing for Cancer, Infection, or Granulomatous Disease
After finding a myelophthisic process, we look for the cause. We use advanced imaging to find hidden tumors or infections in the marrow. These steps help us plan the right treatment.
Common steps include:
- Whole-body PET or CT scans to find primary cancers.
- Special cultures to check for chronic infections like tuberculosis.
- Genetic testing to find specific marrow disorders.
By using these tools, we can find out what’s affecting your marrow. This detailed approach helps us treat the cause, not just the symptoms of anemia.
How Causes and Treatment Differ Across These Anemia Types
Patients with marrow-infiltrating disorders need a custom care plan. The bone marrow is filled with abnormal cells or fibrous tissue. So, standard anemia treatment often doesn’t help much. We need to focus on the disease process affecting blood production.
Treating the Underlying Marrow-Infiltrating Disorder
The main goal is to find and treat the cause of the problem. If it’s cancer, we use chemotherapy or targeted therapy. For chronic infections or granulomatous diseases, we use specific treatments to clear the marrow.
When comparing myelofibrosis vs aplastic anemia, the treatment plans are different. Aplastic anemia might respond to treatments that stop the immune system from attacking. Myelofibrosis treatment focuses on the JAK-STAT pathway or stem cell transplantation for some.
When Transfusions, Growth Factors, or Iron Replacement May Be Used
Supportive care helps while we work on the main issue. Red blood cell transfusions are often needed to fight fatigue and ensure organs get enough oxygen. But, we must watch iron levels to avoid overload.
Growth factors like erythropoietin-stimulating agents are not always effective. The marrow’s structure is damaged, making it hard to respond to these signals. We use them only when there’s a chance for the marrow to work better.
Specialized Management for Myelofibrosis, Leukemia, or Metastatic Cancer
Dealing with advanced diseases needs a team of experts. For myelofibrosis, we might use JAK inhibitors to reduce spleen size. In leukemia, intensive therapy is needed to clear the marrow and start normal blood production again.”The art of medicine consists of amusing the patient while nature cures the disease, but in complex marrow disorders, we must actively intervene to restore the body’s natural balance.”

Why Treatment Must Be Guided by the Cause Instead of the Anemia Alone
Just focusing on hemoglobin levels can be misleading. Treating the anemia without fixing the underlying issue lets the disease get worse. Individualized decisions are key, considering your specific needs and risks.
We aim to treat the main cause of your condition for effective anemia treatment. This approach helps achieve stability and improve your quality of life.

FAQ
What exactly is a myelophthisic process?
myelophthisic process happens when normal bone marrow is pushed out by abnormal materials. This can be due to myelofibrosis, cancer cells, or diseases like sarcoidosis. When the marrow is replaced, it can’t make enough blood cells, leading to myelophthisic anemia.
Why is myelophthisis classified as a hypoproliferative anemia?
Myelophthisis is called a hypoproliferative anemia because the marrow can’t make new red blood cells well. Unlike conditions where red cells are destroyed, here the marrow is damaged or filled up. This means the body can’t make enough new cells.
What does a leukoerythroblastic pattern mean on a blood smear?
leukoerythroblastic smear is a key sign of myelopthisis. It shows immature red and white blood cells in the blood. This happens when the bone marrow is so damaged that these cells are released too early.
How do we distinguish between myelofibrosis vs aplastic anemia?
Both can cause low blood counts, but they’re different. Myelofibrosis fills the marrow with scar tissue. Aplastic anemia has a marrow that’s mostly empty. A bone marrow biopsy is needed to tell them apart.
Are teardrop cells always a sign of myelophthisic anemia?
Teardrop-shaped red blood cells are common in myelophthisic conditions. They’re thought to be shaped by passing through damaged marrow. While they can appear in other conditions, they suggest a marrow-replacing process when seen with immature cells.
How does myelophthisic anemia differ from iron-deficiency anemia?
The main difference is in cell size and marrow response. Iron-deficiency anemia has small, pale cells because of a lack of iron. Myelophthisic anemia has normal-sized cells but a leukoerythroblastic smear and often low platelets and white blood cells.
Why is identifying the cause of myelopthisis so important for treatment?
Finding the cause is key because treating the anemia won’t work if the marrow is replaced. If it’s cancer, treatment focuses on oncology. If it’s an infection, clearing it is needed to improve the anemia.
Can inflammation mimic a myelophthisic process?
Yes, there can be overlap. Chronic inflammation can cause a low red blood cell count by storing iron. But, inflammation alone doesn’t usually cause the marrow scarring seen in myelophthisis. We use tests to tell the difference.;
