Brunner's gland adenoma: a report of two cases

Brunner 's gland adenoma is a very rare benign tumor of the duodenum. Only two cases of the adenoma have been in the file of the surgical pathology unit of Ramathibodi Hospital since 1992 and presented in this communication. The tumor is capable of producing a variety of clinical manifestations. Presently, endoscopic study plays an important role in both detection and diagnostic biopsy. Local excision, either by endoscopy or surgery is the main treatment in symptomatic cases. Ductal malignancy on top of Brunner's gland adenoma was described in one from estimated 200 recorded cases in the English literature since 1835.
