Abstract: Mesenteric leiomyosarcoma (LMS) is a rare gastrointestinal mesenchymal tumor. It was often misdiagnosed as a gastrointestinal stromal tumor (GIST) until the introduction of immunohistochemistry staining (IHC) in 1998. Currently, a positive IHC staining for smooth muscle markers represents the main diagnostic modality.

“…In contrast to metastases from gastrointestinal tumors, primary mesenteric tumors are rare, lymphomas being the most common, followed by usually benign mesenchymal tumors [2]. Mesenteric leiomyosarcoma is very rare, with only 20 cases reported [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]: six were male and 14 female. Age ranged from 13 to 86 years (median 54 years).…”
