Rectosigmoidal hemangioma: Report of two cases

ConclusionsRectosigmoidal hemangioma is of extremely rare occurrence. The diagnosis is based on proctoscopic and radiologic examination. The cause is unknown and the prognosis is always serious because of the danger of uncontrollable hemorrhage that may occur at any moment. Treatment is surgical.

Giant follicular lymphoblastoma of the rectum (brill-symmers disease)

Summary and ConclusionsThe authors have presented a case of giant follicular lymphoblastoma (Brill-Symmers disease) involving the rectum. It is a rare disease which pursues a fairly characteristic clinical course. The lesion can be discovered by proctoscopic examination but, to establish the differential diagnosis, microscopic examination is essential. Biopsy should not be relied upon: the entire lesion should be available for microscopic study. Eventually, the lesion may become malignant. Specific treatment consists of complete removal of the tumor by surgical operation; subsequently, irradiation should be administered to destroy residual cells.

Submucous subserous lipoma of the colon

ConclusionsAmong lipomas of the colon, mixed submucous-subserous lipomas are rare. The etiology is obscure. Diagnosis is difficult and rarely made without radiologic study of the colon with double-contrast technic and air insufflation.Treatment is always surgical and prognosis is good.
