Small Intestinal Obstruction with Intussusception due to Acute Myeloid Leukemia : A Case Report

Abstract EN

Myeloid sarcoma is known to precede the development of acute myeloid leukemia (AML) and can be the only clinical manifestation.

Gastrointestinal involvement by AML is rare with the commonest site being small intestine.

Patients present with vague abdominal pain and/or obstruction.

Prognosis is usually poor as most of them rapidly progress to AML.

We report a case of 25-year-old man with complaints of abdominal pain and vomiting of one-year duration.

OGD scopy revealed infiltration of lesser curvature of stomach.

Subsequently patient came back within a week with signs and symptoms of acute intestinal obstruction for which an ileal resection was done.

Although the histology of stomach biopsy and ileal segments showing similar features were thought to be non-Hodgkin's lymphoma, immunohistochemistry confirmed the diagnosis of myeloid sarcoma.

Bone marrow investigations confirmed involvement by AML.

Patient succumbed to the disease due to extensive involvement of AML.

This case highlights the primary gastrointestinal manifestation of AML which can often prove to be a diagnostic difficulty clinically and histologically.

Prompt diagnosis is essential to hasten the management.
