Pancytopenia occurs when a person has a decrease in all three blood cell types. Pancytopenia has many possible causes: Diseases such as cancer, lupus or bone marrow disorders. A thoughtful history and physical examination along with focused laboratory studies are required to establish a diagnosis and select proper management. The diagnostic approach to an adult patient with pancytopenia will be discussed here. [Medline]. 2005. Townsley DM, Dumitriu B, Young NS.

Townsley DM, Desmond R, Dunbar CE, Young NS. Mexico and Latin America also have high occurrence rates, which are attributed to the liberal use of chloramphenicol. Examination of bone marrow is almost always indicated in cases of pancytopenia unless the cause is otherwise apparent (e.g., established liver disease with portal hypertension). Dyskeratosis congenita is inherited in an X-linked recessive, autosomal dominant, or autosomal recessive manner. Splenectomy is typically performed laparoscopically; even supramassive spleens can be removed by laparoscopic surgery with minimal morbidity. [Medline]. Pancytopenia is low levels of red blood cells, white blood cells, and platelets. One of these genes (FANCD1) is the breast/ovarian susceptibility gene (BRCA2). Bone marrow failure can be inherited or acquired and can involve a single hematopoietic stem cell line or all three cell lines. Bone marrow failure: a child is not just a small adult (but an adult can have a childhood disease). The Ham test, or sucrose hemolysis test, result may be positive in a patient with underlying paroxysmal nocturnal hemoglobinuria, but a recent transfusion with packed red blood cells may induce a false-negative test result (ie, testing normal, transfused red cells). Blood. The severity and extent of cytopenia determine prognosis. A decrease in all three cell lines is the most common manifestation of bone marrow failure.

Finally, it may arise from lymphoproliferative diseases (eg, lymphomas, chronic lymphocytic leukemia) or collagen vascular diseases (eg, systemic lupus erythematosus, refractory anemia), or it may occur during pregnancy. There are only few studies in Pakistani literature on clinical spectrum of pancytopenia. In half of the patients, severe congenital neutropenia is associated with dominant mutations in neutrophil elastase (ELA2, located at band 19p13.3), while a few patients have mutations in GFI-1. In most cases of pancytopenia, referral to a hematologist will be important for purposes of diagnosis and/or management.

Constitutional causes of aplastic anemia include the following conditions: Fanconi anemia - Characterized by familial aplastic anemia, chromosomal breaks, and, in some cases, congenital anomalies of the thumb or kidneys, Dyskeratosis congenita - Another rare disorder, dyskeratosis congenita has a characteristic dermatologic manifestation of nail dystrophies and leukoplakia; patients with this disease develop aplastic anemia in their second decade of life, Shwachman-Diamond syndrome - This disorder consists of exocrine pancreatic insufficiency and bone marrow failure; occasionally, cartilage and hair hypoplasia occur, resulting in short stature and dysostosis.
