Dermoid cyst of pancreas: A rare entity

Abstract

Dermoid cysts or mature cystic teratomas are mesenchymal neoplasms most commonly found in the ovaries, but which may occur in any location along the pathways of ectodermal cell migration. Pancreatic dermoid cysts are rare entity and preoperative diagnosis is difficult. A 27-year-old female presented with upper abdominal pain and vomiting of 1 week duration without jaundice, diarrhea, and fever. Ultrasound abdomen showed a 4 cm × 3 cm cyst in the head of pancreas with smooth walls. Magnetic resonance cholangiopancreatography showed large multilocular cystic lesion in pancreatic head region which displaces pancreas anteriorly and mildly superiorly. Endoscopic ultrasound-guided cyst fluid aspiration was done which revealed high cyst fluid amylase and carcinoembryonic antigen. At surgery, a pylorus-preserving pancreatoduodenectomy was done. Histopathologic examination revealed a rare diagnosis of dermoid cyst of pancreas. This case report highlights difficulty in preoperative diagnosis of cystic lesions of pancreas by imaging. Therefore, we want to highlight the literature in this rare entity.
