    Abstract

    Malignant fibrous histiocytoma (MFH) is the most frequent malignant soft tissue tumor in adults. A primary MFH occurs most commonly in the extremities and the trunk, but rarely in the pelvic cavity. We report a case of malignant fibrous histiocytoma of the unknown origin in the pelvic cavity with a review of the literature. The neoplasm occurred in the pelvic cavity of 53-year-old female who complained of enlarging nontender mass in the lower abdomen. The final diagnosis was based on the pathological report of the surgical specimen.

    Fig. 1
    Abdominal CT scan shows about 10 cm sized heterogeneously enhancing solid mass in pelvic cavity, diffusely attached to anterior wall of uterus and small bowel loops.

    The gross finding of surgically removed retroperitomeal mass: This tumor measuring 12.5X10X6 cm, 400 mg, is gray-white, fresh mass with multifocal hemorrhagic necrosis.

    Fig. 3
    The tumor cells are arranged with short fascicles consisting of pleomorphic spindle cells (H&E, X200).

    Fig. 4
    There are pleomorphic spindle cells in myxoid background (H&E, X200).

    Fig. 5
    On immunohistochemically, tumor cells are positive for vimentin (vimentin, X400).
