title: [A case of primary leiomyosarcoma of the small bowel with hepatic portal venous gas].
abstract: A 92-year-old woman was admitted with speech disturbance. She had severe anemia (hemoglobin, 6.3g/dl), and abdominal ultrasonography revealed hepatic portal venous gas and an intra-abdominal tumor. Abdominal computed tomography also revealed an irregularly enhanced intra-abdominal tumor, 32x35mm in diameter, which was surgically resected. The tumor was located in the small intestine. Histopathological examination revealed spindle-shaped atypical cells. Immunological evaluation showed the tumor to be SMA (+), c-kit (-), CD34 (-), S100 (-). The Ki-67/MIB1 labeling index was 2.3%. The tumor was diagnosed as leiomyosarcoma of the small bowel. The patient recovered after surgery and was discharged.
