A CASE OF ENDOMETRIOSIS OF THE ILEUM PRESENTING WITH SYMPTOMS OF PERITONITIS

Abstract

A 37-year-old woman was admitted to the hospital because of intermittent abdominal pain. There were tenderness and muscular defense in the right lower abdomen. Ultrasonography and computed tomography showed thickening of the terminal ileum wall and dilatated small intestine. The symptoms did not improve and considering possibly malignancy, an operation was performed. A hard tumor was palpable at the terminal ileum with stenosis. There was no apparent abnormality in the uterus and ovary. Under the diagnosis of stenosis of terminal ileum, ileocecal resection was performed. On the resected material, focal edema on the mucosa and stenosis of the terminal ileum were noted. The serosa and muscle layer were hard like a scar. Microscopical examination revealed endometrial glands surrounded by stroma in the subserosal layer of the ileum, and the histological diagnosis was endometriosis of the ileum.
