초록
Solitary fibrous tumor is an uncommon spindle cell mesenchymal neoplasm with unpredictable behavior, usually arising in the pleura of the thoracic cavity. It is rarely found in the head and neck, and malignant solitary fibrous tumor is even rare. Malignant criteria of solitary fibrous tumor includes increased cellularity, increased mitoses (＞4 mitoses/10HPF), cytologic atypia, tumor necrosis and/or infiltrative margin. The treatment of malignant solitary fibrous tumor is complete surgical excision and adjuvant radiotherapy. We report a case of malignant solitary fibrous tumor originating from the parotid gland, relapsed very quickly and grown very rapidly in 6 weeks after surgical resection.
Abstract
Solitary fibrous tumor is an uncommon spindle cell mesenchymal neoplasm with unpredictable behavior, usually arising in the pleura of the thoracic cavity. It is rarely found in the head and neck, and malignant solitary fibrous tumor is even rare. Malignant criteria of solitary fibrous tumor includes increased cellularity, increased mitoses (＞4 mitoses/10HPF), cytologic atypia, tumor necrosis and/or infiltrative margin. The treatment of malignant solitary fibrous tumor is complete surgical excision and adjuvant radiotherapy. We report a case of malignant solitary fibrous tumor originating from the parotid gland, relapsed very quickly and grown very rapidly in 6 weeks after surgical resection.
