Pancreatic Carcinosarcoma Presenting as Pancreatic Cystic Neoplasm / 대한내과학회지

ABSTRACT

A 66-year-old woman presented with severe abdominal pain. Abdominal computed tomography revealed a large multicystic mass with a solid component at the tail portion of the pancreas. Distal pancreatectomy was performed with a preoperative diagnosis of mucinous cystic neoplasm. The solid component of the lesion showed both adenomatous and sarcomatous characteristics on histological examination. Immunohistochemical studies showed epithelial cells positive for cytokeratin and an immunoreactive sarcomatous component positive for vimentin. We present here a case of carcinosarcoma of the pancreas with a review of the literature.
