A case of pancreatic metastasis from leiomyosarcoma of the retro peritoneum

Abstract

A 44-year-old woman underwent left nephrectomy with resection of retroperitoneal tumor (leiomyosarcoma) on April, 1997. Subsequently, recurrence was diagnosed and she underwent partial hepatectomy of S2 and S4 on early in February, 2000, and lateral segmentectomy of the liver on middle of December, 2001. Both of the resected liver tumors were diagnosed as histologically metastases from leiomyosarcoma. On late in July, 2002 she was admitted with abdominal pain, and abdominal computed tomography (CT) showed tumor, 2cm in diameter, in the tail of the pancreas. Distal pancreatectomy with splenectomy was carried out on late in August, 2002 and also histologically diagnosed as metastases to the pancreas. She has been alive 12 months postoperatively without relapse. This case was very rare and we did find a few reports in which cases of resection of the pancreatic metastasis from soft-tissue sarcoma with or without other organ metastases could expect consequence in the long-term survival. Resection may one of treatments for cases like this diagnosed as pancreatic metastasis. ©2005 the Japanese Society of Gastroenterological Surgery.
