Primary solid papillary tumor of the liver

Abstract

Solid papillary tumor (SPT) is an uncommon lesion of the pancreas whose origin and behavior are poorly understood. Very rare cases of primary extra-pancreatic SPTs have been described, and their clinical, histological, immunophenotypic and ultrastructural features seem to be similar to those arising in the pancreas. Here we report a case of primitive SPT of the liver, the second case described in the literature so far.
