A rare case of adult intestinal intussusception: epithelioid type mesenchymal tumor of the small intestine.

Small bowel intussusception is a rare cause of adult acute abdomen, in which an intraluminal neoplasm is the most frequent cause. Small bowel tumors are uncommon and can have a long delay prior to diagnosis. We present a case of intestinal intussusception originating from a rare variant of small bowel mesenchymal tumor, presenting with a hematologic disorder.
