ABSTRACT
Elliptocytosis has been known to be a rare disease, especially in oriental people. Most of them are transmitted as an autosomal dominant trait but we experienced one case of transient elliptocytosis associated with acute lymphoblastic leukemia by morphologic examination of the peripheral blood and bone marrow biopsy. The results of the peripheral blood smears of the patient and his family are as follows : he showed about 50~60% of elliptocytes and anemia without hemolytic event; his family, however, showedno sign of elliptocytosis. The patient was treated for acute lymphoblastic leukemia. On follow-up check after one month, the peripheral blood showed almost normal RBC morphology. Therefore, we diagnosed this case as transient elliptocytosis associated with acute leukemia. So we report a case of transient elliptocytosis associated with acute leukemia with a brief review of the relevant literature.
