Johns Hopkins Pathology
 
Key Points:
  • Mucinous Cystic Neoplasm
  • Solid-pseudopapillary Neoplasm

The gross appearance of a pseudocyst resembles that of a mucinous cystic tumor and a solid-pseudopapillary tumor. The absence of any epithelial lining or epithelial tissue in pseudocysts excludes the diagnosis of a cystic neoplasm. In addition, mucinous cystic tumor and solid-pseudopapillary tumor predominantly occur in women, whereas pseudocysts are associated with a history of pancreatitis and usually chronic alcoholism and occur more often in men.
