Leiomyosarcoma of the Pancreas with Liver Metastases as a Paradigm of Multimodality Treatment: Case Report and Review of the Literature.

Primary leiomyosarcoma is a rare malignant neoplasm, although it is the most common primary pancreatic sarcoma [1]. It accounts for 0.1 % of malignant pancreatic neoplasms [2], and it seems to arise from smooth muscle cells of ducts or blood vessels within the pancreas [3] Pancreatic leiomyosarcoma is a highly aggressive neoplasm in which widespread metastases occur frequently and the liver is typically affected [4], so the prognosis is generally bad [5]. Radical resection of the primary lesion seems to offer the best possibility for cure [6]. We report a case of primary leiomyosarcoma of the pancreas with synchronous hepatic metastases occurring in a 54-year-old female who was treated with repeated surgical excision together with different chemotherapeutic regimens
