 A 46-year-old woman presented with an asymptomatic pancreatic tail tumor, which was detected incidentally on plain computed tomography as an examination for a growing uterine myoma. Dynamic computed tomography revealed a 28-mm solid tumor with a smooth surface, protruding from the pancreatic surface caudal to the pancreatic tail, with increased late enhancement in the dorsal part of the tumor. Magnetic resonance imaging revealed that the tumor had low intensity in T1-weighted images and slight high-intensity in T2-weighted images. Endoscopic ultrasound-guided fine-needle aspiration samples contained only fibrous stromal tissue with spindle cells, even though the needle definitely punctured the tumor. The preoperative diagnosis was suspected to be pancreatic neuroendocrine tumor, and laparoscopic distal pancreatectomy with splenectomy was planned. Intraoperatively, the tumor protruded to the caudal side of the pancreatic tail and was pedunculated with a 1-cm-wide stem. Laparoscopic partial pancreatectomy was performed because intraoperative rapid pathological diagnosis indicated a benign tumor. The final pathological diagnosis was pancreatic hamartoma.
