We report a case of duodenal Gangliocytic Paranglioma in a 73 year old man, who presented with a history of melena. An upper gastrointestinal barium study showed a polyp located in the second portion of the duodenum. This lesion was endoscopically resected. Pathological examination revealed a Gangliocytic Paraganglioma. We describe the general characteristics of this neoplasm, as well as the theories about its histogenesis.

Collagenous colitis is a newly recognized entity presenting clinically as chronic watery diarrhea and histologically by a thickened subepithelial collagenous band in colonic biopsies. We report the case of a middle aged woman affected of acute diarrhea in whom, after ruling out its main etiologies, the diagnosis of collagenous colitis was made.

A 28 year old patient with a moderate attack of ulcerative colitis was treated with sulfasalazine. Ten days after, the patient was admitted with clinical and laboratory symptoms of acute pancreatitis (serum amylase 631 u., serum lipase 1080 u. urine amylase, 910 u.). Upon recovery, sulfasalazine was reintroduced at lower dosage (2 Gm/day), and the patient repeated the clinical and biological picture of acute pancreatitis (serum amylase of 710 and lipase 1010 u.) CAT scan showed pancreatic edema and ultrasonography demonstrated a normal gallbladder. The symptoms and laboratory abnormalities disappeared in three days after stopping sulfasalazine. The patient has been followed-up for one year without recurrence of pancreatitis on maintenance treatment with 1.5 Gm 5-Aminosalicylic acid.
