[A case of malignant fibrous histiocytoma of the cecum].

ABSTRACT

A case of primary malignant fibrous histiocytoma (MFH) of the cecum was reported. Patient was a 52-year-old female, and complained of right lower abdominal pain. The barium enema and abdominal computed tomography demonstrated a localized mass involving the entire circumference of the cecum. Right hemicolectomy was performed and the resected specimen revealed a tumor of 8 X 6 X 5 cm in size extending to the entire circumference of the cecum. The histopathological examination revealed a storiform pattern, which was diagnostic of MHF. The tumor proliferated chiefly in the subserous tissue and partially infiltrated the tunica muscularis propria. The postoperative course was uneventful and she showed no sign of recurrence at 15 months after operation. This is the ninth reported case of primary MFH in digestive organs.
