Oral undifferentiated high-grade pleomorphic sarcoma: report of a case
چکیده انگلیسی

The current World Health Organization classification considers the existence of an undifferentiated unclassifiable category of pleomorphic sarcomas, defined as a group of pleomorphic high-grade sarcomas. Undifferentiated high-grade pleomorphic sarcoma represents about 5% of all soft tissue sarcomas in adults and occurs more commonly in the extremities. In the oral cavity, undifferentiated pleomorphic sarcoma is extremely rare. We report a case of undifferentiated high-grade pleomorphic sarcoma located in the floor of the mouth in a man 56 years old. Microscopically, spindle-shaped cells with accented pleomorphism arranged in a storiform pattern, several bizarre giant cells, and frequent atypical mitoses were observed. The tumor cells were positive only for vimentin, with focal positivity for CD68. The patient was treated by surgery and postoperative radiation therapy, and after 25 months, no recurrence was observed.
