[Rectosigmoid endometriosis with lymph node involvement].

Endometriosis mainly affects women of a fertile age and is usually located in the pelvis. Extrapelvic involvement is less frequent. We present the case of a female patient with endometriosis of the rectosigmoid and mesenteric lymph nodes, which is an extremely rare finding. Although the most widely accepted theory of the pathogenesis of this disease postulates retrograde menstruation through the Fallopian tubes with subsequent implantation in the peritoneum, these findings support lymphatic dissemination of endometrial cells as a theory of pathogenesis in cases of extrapelvic involvement.

[Endometriosis: an infrequent cause of colonic obstruction].

Endometriosis localized in the intestinal wall is not an infrequent finding. Diagnosis is difficult given the diverse symptomatology presented with unspecific abdominal pain being the most common. Implantation of endometrial tissue in the intestinal wall may involve the mucosa and present as rectorhagia, with colonscopic exploration providing diagnosis by biopsy of the affected area. In other cases this may only involve the intestinal wall producing very varied symptomatology. Presentation as a picture of colon obstruction is little reported. The main problem is its difficult differential diagnosis with neoplasm which, in most cases, leads to surgery. A case of colon obstruction provoked by implantation of endometrial tissue in the wall of the sigma which was surgically resolved is herein presented.

[Abdominal pain and ascites as manifestations of hereditary angioneurotic edema].

Hereditary angioneurotic edema (HAE) is an infrequent autosomal dominant disorder characterized by a decrease in the levels or a dysfunction of the complement C1 inhibitor factor (C1 inh). The clinical presentation varies widely and involves any area of the organism. Gastrointestinal involvement is usually as abdominal pain and may be accompanied by ascites. De novo diagnosis of HAE with abdominal pain and ascites as a form of presentation is difficult with differential diagnosis with abdominal pain of unknown origin. The appearance of ascites is rare with few cases reported in the literature. Both abdominal pain and ascites disappear a few days after initiation of medical treatment. Occasionally exploratory laparotomy has been required. A new case of abdominal pain and ascites as manifestations of HAE is herein reported.
