[Carcinoid tumor in Meckel's diverticulum: case presentation and review of the literature].

Meckel's diverticulum is the most common anomaly of the gastrointestinal tract. Neoplasms are extremely rare. We report a case of carcinoid tumor of Meckel's diverticulum in a patient with acute abdominal pain. So far, 111 cases have been reported. Review of the literature reveals that carcinoids are the most common malignant tumors of Meckel's diverticulum. Two thirds of the patients remain asymptomatic. Metastases are seen in 25% at diagnosis. The probability of metastases depends on the size of the primary tumor. Because of the early metastases rate even in small tumors, aggressive surgical management is justified.
