Thrombocytopenia-absent Radius Syndrome with Vitamin B12 Deficiency: Case Report with Literature Review

Abstract

Thrombocytopenia-absent radius syndrome (TAR) is a rare malformation in which thrombocytopenia is associated with lateral radial bone aplasia. The major cause of mortality is hemorrhage which is usually limited to first 14 months of life. Thrombocytopenic episodes decrease as age advances. We present a 22 years old male who was diagnosed as nutritional vitamin       B12 deficiency. Despite of giving treatment his platelets did not improve so the patient was   reviewed and a revised diagnosis of TAR Syndrome with nutritional vitamin B12 deficiency          was made.
