초록
Atypical fibrous histiocytoma is a rare variation of cutaneous fibrous histiocytoma. The histologic features of atypical fibrous histiocytoma include a proliferation of pleomorphic, spindle, and/or polyhedral cells with mainly large, hyperchromatic, irregular, bizarre nuclei, set in a background of classic features of fibrous histiocytoma. It includes spindle cell areas showing a storiform pattern and thickened, hyaline collagen bundles. Generally, atypical fibrous histiocytoma is treated by complete excision, and in most cases, a benign outcome is expected. However it has a tendency to recur locally after excision and there are a few recent reports of occasional distant metastasis. Recently we experienced a case of atypical fibrous histiocytoma in nasal cavity. Therefore we present this case of atypical fibrous histiocytoma with a brief review of literature.
Abstract
Atypical fibrous histiocytoma is a rare variation of cutaneous fibrous histiocytoma. The histologic features of atypical fibrous histiocytoma include a proliferation of pleomorphic, spindle, and/or polyhedral cells with mainly large, hyperchromatic, irregular, bizarre nuclei, set in a background of classic features of fibrous histiocytoma. It includes spindle cell areas showing a storiform pattern and thickened, hyaline collagen bundles. Generally, atypical fibrous histiocytoma is treated by complete excision, and in most cases, a benign outcome is expected. However it has a tendency to recur locally after excision and there are a few recent reports of occasional distant metastasis. Recently we experienced a case of atypical fibrous histiocytoma in nasal cavity. Therefore we present this case of atypical fibrous histiocytoma with a brief review of literature.
