Intestinal Ameboma Involving the Jejunum: First Case Reported in Medical Literature

We present the case of a 58-years-old caucasian male who was hospitalized in our hospital with an early diagnosis of a jejunal tumor. However, all the instrumental and laboratory testing conducted were inconclusive and a preoperative diagnosis was not established. Patient was scheduled for surgery and en-bloc resection of the jejunal mass was performed. Microscopic analysis of the specimen reported the presence of intense mixed lympho-granulocytic inflammatory infiltrate of the mucosa associated with entamoeba parasites and a diagnosis of intestinal ameboma was ruled out. Ameboma is a rare complication of chronic amoebic colitis. usually found in the cecum and ascending colon. To our knowledge, this is the first case of an intestinal ameboma involving the jejunum to be reported in medical literature.
