Cystadenoma of the pancreas--an unusual presentation.

Cystadenoma is a rare lesion of the pancreas. A case is reported in which the tumour was initially misdiagnosed as a pseudocyst and inappropriate surgery performed. The patient subsequently presented with gastro-intestinal haemorrhage and the tumour was resected. The diagnosis and management of cystic lesions of the pancreas are discussed, stressing the need for complete pre-operative investigation in order that incorrect treatment is avoided.
