Post transfusion purpura in a thalassemic child.

Post transfusion purpura (PTP) is a rare condition and only 200 cases have been reported so far. It is commonly seen in women, with a preponderance in the sixth and seventh decade. Majority of these cases have been observed in whites and the condition is rare among Asian patients(l). It has not yet been reported in children(2). PTP is characterized by the development of thrombocytopenia associated with variable bleeding manifestations following a blood transfusion. It occurs in patients whose platelets are PL negative and who have been sensitized to the platelet antigens following multiple blood transfusions and in women during pregnancy. We report a case of PTP in a thalassemic child.
