A case of a solid-pseudopapillary neoplasm arising from an ectopic pancreas in the retroperitoneal tissue in a 40-year-old woman is presented. A 7.5-cm, well encapsulated tumor, adherent but not infiltrating the spleen and the upper left kidney was surgically resected. Hystologically, the tumor showed a solid and papillary pattern of polygonal epitheliod cells organized around a fibrovascular stalk. Most of the tumor cells had an eosinophil cytoplasm with focal aggregates of PAS positive hyaline globules and showed a positivity for vimentyn, (1-antitrypsin and (1-antichemotrypsin. All the tumor cells were negative for estrogens or progesterone receptors. The incidence of both ectopic pancreas outside of the gastrointestinal wall and solid and pseudo-papillary neoplasm of the pancreas is very rare. To our knowledge this is the 4th case reported in literature of an association between such 2 conditions.
