A case of a solid cystic tumor (SCT) of the pancreas with massive hemoperitoneum occurring in a 31-year-old woman is reported. She was admitted with abdominal pain and rebound tenderness. Computed tomography (CT) disclosed a large tumor consisting of both solid and cystic components in the body of the pancreas. Within 12 hours after admission, she exhibited exacerbation of pain and hemoperitoneum on CT with deterioration of general condition and anemia. Celiac artery angiography demonstrated the tumor as a hypovascular mass. SCT of the pancreas was suspected, and emergent laparotomy was performed. In the surgical procedure, tumor in the body of the pancreas with rupture was detected. Distal pancreatectomy was performed with removal of the regional lymph nodes. There was no evidence of metastatic disease in the abdomen. The cut surface of the tumor exhibited areas of cystic degeneration containing hemorrhagic friable materials. Microscopically, the tumor cells were mainly cubic or cylindrical peripherally in pseudo-papillary formation. Postoperative recovery was normal and she was discharged on the 15th postoperative day. Three years after operation, she is free of disease without findings of recurrence.
