[Intestinal malacoplakia in childhood. Report of 5 cases].

We studied 5 children with intestinal malakoplakia who were seen during a period of 10 years. Four were male and one female. The main clinical manifestations were: chronic bloody and mucous diarrhea, abdominal pain and polypoid masses detected by rectal maneuver. Either the radiological study as well as endoscopy showed the presence of stenosis and polypoid masses (pseudopolyps). Two patients underwent laparotomy and a tumoral infiltration at the level of rectal-sigmoid and cecal appendix was found. Histological diagnosis proves to be definitive in these case. Drug treatment has been with bethanechol, trimethoprim-sulfamethoxazole in three patients. We conclude that intestinal malakoplakia is more common that ulcerative colitis in our children population attending at this institute. Therefore, the presence of intestinal malakoplakia must be ruled out in every child having chronic bloody and mucous diarrhea, presenting as well pseudopolyps.

[Antral membrane. Presentation of a case].

A case of antral membrane in a 23 month old child is presented. He developed an extremely rapid clinical course characterized by vomiting, 4 kg weight loss and acute malnutrition. The UGI showed a probable antropyloric obstruction which was confirmed by endoscopy and lately by surgery. It is suggested that in the approach of a patient with vomit it is very important to make an oriented clinical history and always complete the study of the patients with radiological and endoscopic procedures.
