A case of a solid and papillary (solid-cystic) tumor of the pancreas occurring in a 36-year-old man is herein reported. This patient was admitted with left hypochondrial pain and diagnostic imaging detected a large tumor consisting of both solid and cystic components in the tail of the pancreas. A distal pancreatectomy with splenectomy was performed. The resected tumor was diagnosed as a solid and papillary tumor of the pancreas by pathological examination. Detailed immunohistochemical studies showed that the tumor consisted of cells both exocrine and endocrine in character. Thus, this case appears interesting from the point of cellular differentiation in solid and papillary tumors, since they are generally considered to have an acinar cell origin.
