Acute myeloid leukemia presenting as "bowel upset": a case report.

Myeloid sarcomas (MS) are the extramedullary presentation of acute myeloid leukemias. At times, they are difficult to diagnose due to lack of any supportive findings in peripheral blood/bone marrow aspirate examination. The involvement of gastrointestinal tract (GIT) by myeloid sarcoma is rare phenomenon. This diagnostic challenge becomes more complex when it is added by vague clinical symptoms. Many times, they have been misdiagnosed as Non-Hodgkin's lymphoma, small round cell tumour or carcinoma. Here, we are reporting a case of myeloid sarcoma with no haematological abnormality which presented with the symptoms of bowel obstruction and a rare combination of inv. (16) and trisomy 22. The journey to reach the conclusive diagnosis in this case is interesting and sensitizes us to have high index of suspicion in a case, where there is paucity of clinical evidences.
