Undiagnosed dual blood disorder – Thalassemia with acute myeloid leukemia

Abstract

Thalassemia syndromes represent a group of inherited disorders characterized by decreased synthesis of one or more of the four globin chains in hemoglobin. The clinical spectrum ranges from asymptomatic carrier state to transfusion-dependent severe disease. The availability of better treatment options has increased the life expectancy in these patients and consequently paved the way to develop malignancies. Although many studies are published on the association of solid organ and lymphoid malignancies, only one case has been reported so far for acute myeloid leukemia (AML) coexisting with thalassemia syndromes. Herein, we report the first case of AML associated with beta-thalassemia in an adult Indian expatriate woman in Qatar. She presented with prolonged bleeding after a dental procedure. She was diagnosed as concurrent AML and beta-thalassemia trait on the laboratory evaluation. This case signifies the use of peripheral blood film evaluation for any abnormal hemograms in the modern era of automation. It also warrants caution for clinicians in suspecting malignancies in thalassemia although direct genetic linkage or associated risk is a matter of research.
