ABSTRACT
We report a rare case of adenocarcinoma arising from heterotopic pancreas in splenectomy specimen operated for a Splenic Cyst. This 40 year old female patient presented with vague upper abdominal pain and swelling. USG showed a large cyst within the spleen. The cyst along with the spleen is removed after laparotomy. The pancreas and other abdominal organs were unremarkable on ultrasonography and intraoperative examination. Gross examination showed a cyst with a smooth lining, entirely within the spleen. A small locule, communicating with the main cyst showed small papillary projections. On light microscopy, the cyst wall is lined by single layer of columnar cells. Section from papillary areas showed histological appearance of papillary adenocarcinoma. Remnant of normal pancreatic tissue was discovered at the wall of the cyst. We presume an origin from heterotopic pancreatic tissue in the spleen for this neoplasm and reporting the case for its rarity.

A 9 year old female presented with 8 months history of right sided chest pain and respiratory distress. Chest X-ray revealed a large anterior mediastinal mass.
