Acute erythroleukemia--M6B.

Acute Erythroleukemia is a rare disorder of hematopoietic system, accounts for 1-3% of all acute leukemia and 15% of myeloid leukemia. Recently, the World Health Organisation & Society of Haematopathology proposed a change in the categorization, with M6a and M6b subgroups of the original FAB classification. Hereby we report a case of acute erythroleukemia--M6b subtype, presented with pain abdomen and vomiting. The patient died within two days. The case is being reported for its rarity and uncommon presentation.
