RATIONALE: Pancreatic tail cystic lesions are increasingly encountered in clinical practice, however, it is difficult to make a correct diagnosis preoperatively because there are many types of pancreatic neoplastic and non-neoplastic cysts. Epidermoid cyst in an intrapancreatic accessory spleen (ECIPAS) is a rare non-neoplastic cyst locating in the pancreatic tail, and it is commonly misdiagnosed as another cystic neoplasm. PATIENT CONCERNS: A 51-year-old man was admitted for investigation of abdominal pain. The physical examination and laboratory tests found no abnormalities, except for an elevation of carbohydrate antigen (CA)19-9. Imaging revealed a cystic lesion within the pancreatic tail, and the solid component surrounding the cyst was enhanced similarly to those of the splenic tissue. DIAGNOSIS: ECIPAS was diagnosed based on the pathology after surgery. The mass was composed of a cyst and brown solid spleen-like tissue. The microscopic analysis demonstrated that the solid component was accessory splenic tissue, and the cyst wall was lined with a thin stratified squamous epithelium. INTERVENTIONS: Laparoscopic spleen-preserving distal pancreatectomy was performed. OUTCOMES: The patient was discharged on day 5 postoperatively after an uneventful recovery. CA19-9 returned to normal after surgery. During a 2-years follow-up, there was no evidence of tumor recurrence. LESSONS: Although rare ECIPAS should be considered in the differential diagnosis of pancreatic tail cystic ...
