How to tell apart aplastic anemia and pancytopenia
In aplastic anemia, the bone marrow is “empty” (all that’s there are scattered lymphocytes and a rare hematopoietic precursor) and the blood shows a pancytopenia. Sometimes the cause can be determined (for example, the patient has taken a drug that can cause marrow aplasia), but often no particular cause can be found.

2023年8月23日 · Pancytopenia caused by bone marrow failure is known as aplastic anemia. Aplastic anemia could be idiopathic/autoimmune, secondary to infections (such as parvovirus B19, hepatitis, human immunodeficiency virus (HIV), cytomegalovirus, or Epstein-Barr virus), after drug toxicity, or chemotherapeutic agents (methotrexate, dapsone, carbimazole ...
Difference Between Aplastic Anemia and Pancytopenia
Pancytopenia is most commonly seen in aplastic anemia. In aplastic anemia, our immune system attacks the healthy cells of bone marrow. It is triggered due to exposure to chemotherapy, radiotherapy (used in cancer); chemicals like benzene and insecticides.

3.1.1. Acquired aplastic anemia Aplastic anemia is caused by failed hematopoiesis either due to an acquired or a congenital cause. Several observational studies from South East Asia looking for the causes of pancytopenia by bone marrow examination point to aplastic anemia and leukemia being the most common cause in children [5,6] and aplastic ...

Aplastic anemia is defined as pancytopenia with hypocellular bone marrow in the absence of an abnormal infiltrate and with no increase in reticulin. 1 Dr. Paul Ehrlich, who treated a young woman who died following an illness characterized by bleeding, severe anemia, and high fevers, first described the term in 1888. Her bone marrow was analyzed ...
Aplastic Anemia vs Pancytopenia: Difference and Comparison
Aplastic Anemia is when the bone marrow does not produce enough blood cells, while Pancytopenia is when all types of blood cells are reduced in number. Aplastic Anemia can be caused by genetic factors, exposure to toxins, or certain medications, while infections, autoimmune disorders, or cancer can cause Pancytopenia.
