RESUMO
Primary colonic lymphoma is rare and accounts for less than 1% of colon malignancies. Moreover, diffuse neoplastic invasion of the colon is exceptional. This case describes a patient with primary non-Hodgkin's lymphoma of the colon presenting as toxic megacolon. This unique presentation is the first case reported in the literature of a diffuse colonic lymphoma diagnosed in the setting of a toxic megacolon. Histological confirmation was performed on the piece of colectomy.

The anomalies related to omphalomesenteric duct remnant constitute an uncommon cause of intestinal obstruction, of which Meckel"s diverticulum and its variants represent the most important clinical presentation. In most cases they are asymptomatic and usually affect young patients. When symptomatic, they usually present episodes of gastrointestinal bleeding or acute abdomen syndromes caused by strangulation of intestinal loops as a result of fibrous intraabdominal remnants or inflammation produced by the diverticulum. In most cases, the unexpected presence of these alterations makes intraoperative diagnosis necessary. Treatment is surgical and consists in exeresis of the diverticulum or the fibrous band causing the clinical picture. We report two cases of persistence of the vitelline duct resolved by laparoscopic approach.
