Nonfunctioning islet cell carcinoma of the pancreas associated with massive intra-abdominal hemorrhage.
Pancreatic islet cell tumors are rarely associated with intra-abdominal hemorrhage. We report herein a rare case of nonfunctioning islet cell carcinoma associated with massive hemorrhage into the abdominal cavity caused by spontaneous rupture of the tumor. A 44-year-old man presenting with sudden upper abdominal pain was admitted to his local hospital on April 18, 1994. On April 19, a laparotomy was performed with the diagnosis of peritonitis. Massive hemorrhage of unknown origin occurred, and he was transferred to our hospital in a state of hypovolemic shock. Imaging findings revealed massive hematoma in the abdominal cavity and a hypervascular tumor arising from the body of the pancreas. Because the hemorrhage was life-threatening, an emergent re-laparotomy was performed on April 20. Apart from the massive hemorrhage, a pancreatic tumor (60 x 35 x 30 mm in size) with spontaneous rupture was noted. Distal pancreatectomy, combined with splenectomy and removal of the hematoma, was performed. Histological findings revealed an islet cell carcinoma of the pancreas with venous invasion. Peritoneal dissemination, liver metastasis, and lymph node metastasis were not observed. The patient is alive without recurrence 6 years and 5 months after the operation.
