ALMEIDA, N. et al. Adenoma seroso oligoquístico do pâncreas : a propósito de um caso clínico. []. , 13, 3, pp.147-151. ISSN 0872-8178.

We present the case of a fifty years old patient who was first seen in the Emergency Service with a three month history of epigastric pain, without previous pancreatitis or alcohol consumption. The abdominal ultrasound has shown a cystic lesion of the pancreas confirmed by CT scan. However, its ethiology was not determined even after ultrasound guided aspiration of the cyst fluid. The patient was submitted to cephalic pancreatoduodenectomy (Whipple's resection) after an inconclusive extemporaneous biopsy but the histological observation of the surgical specimen revealed a serous oligocystic adenoma with some features of obstructive chronic pancreatitis. This is a rare condition and although the hypothesis of serous cystadenoma was not excluded "ab initio", it was one of the least probable.
