Epidermoid cyst in the intrapancreatic accessory spleen is extremely rare condition which could be mistaken for pancreatic cystic neoplasm. We report two cases of epidermoid cysts of intrapancreatic accessory spleen which mimicking pancreatic cystic neoplasm. Two patients, both male, aged 47 and 53 respectively were referred to our department for pancreatic mass. One was asymptomatic, whereas the other presented worsening abdominal pain and progressive weight loss. In both cases, the mass with cystic component was detected in the pancreatic tail in a computed tomography scan. Under a suspicion of pancreatic cystic neuronendocrine tumor, they underwent a distal pancreatectomy. Pathologic feature of resected specimens were shown to benign squamous lined cyst with splenic tissue in and around cyst wall which suggested that epidermoid cysts in the accessory spleen. We should take into account the possibility of epidermoid cyst in the intrapancreatic accessory spleen in the differential diagnosis of pancreatic cystic lesion.
