De Novo Myeloid Sarcoma as a Cause of Small Bowel Obstruction: A Case Report

Myeloid sarcoma (MS) is an extremely rare disease, closely correlated to Acute Myeloid Leukamia (AML) and presenting as a tumoral lesion in potentially any anatomic location. It is seen either concomitant with AML, during remission, or more seldom, prior to any detectable haematological abnormality. While MS remains a difficult diagnosis, this rare tumor must be included in the differential diagnosis of atypical, local obstructive abdominal processes, especially when coinciding with a myeloproliferative disorder. We present a case report of an otherwise healthy young patient with small bowel obstruction due to an invasive ileal mass, histologically diagnosed as a myeloid sarcoma.
