Carcinoid tumor.A 64-year old man with small bowel obstruction. He did not settle with conservative treatment and underwent a laparotomy. A stenosing lesion was found in the distal jejunum. This was associated with enlarged mesenteric nodes. A segmental resection was performed. The lesion proved to be a carcinoid tumor.
The photographs show the serosal and mucosal aspects with the cicratrising tumor. The ulcerating neoplasm is in the middle of the photograph with the dilated segment of intestine inferiorly.
Primary small bowel malignancy is rare. Carcinoid tumors of the small bowel are typically slow growing and often remain asymptomatic, being incidental findings at autopsy. When they do cause symptoms, they tend to produce obstruction or the carcinoid syndrome.
