In this study we have put together our accumulated experience with cystic manifestations of various solid tumors of the pancreas. Methods From 2000 to 2006 376 patients with pancreatic solid tumor resections were reviewed. Ten of these tumors appeared on radiological imaging studies as cystic lesions. We performed a retrospective review of medical records and pathologic findings of these 10 cases. Results Of the ten cases in which solid tumors of the pancreas manifested as cystic lesions six were PDAC with cystic degeneration two were SPT undergone complete cystic change one was cystic PET and one was a cystic schwannoma. The mean tumor size of the cystic portion in PDAC was cm and three patients were diagnosed as pseudocyst with or without cancer. Two SPT were found incidentally in young women and were diagnosed as other cystic neoplasms. One cystic endocrine tumor was preoperatively suspected as intraductal papillary mucinous neoplasm or mucinous cystic neoplasm. Conclusions Cystic changes of pancreas solid tumors are extremely rare. However the possibility of cystic manifestation of pancreas solid tumors should be kept in mind. Keywords solid cystic pancreas tumor Background Pancreatic cystic tumors are frequently and increasingly diagnosed due to improvement of imaging quality and increased frequency of imaging diagnosis. Interestingly solid pancreas neoplasma may undergo degeneration or change in its structure to appear as cystic tumors masking its originality as a solid .
