Clear cell sarcoma of the jaw: a case report and review of the literature.

Clear cell sarcoma (CSS) is a unique malignant soft tissue tumor that mainly occurs from the aponeurotic tissue and tendons of extremities. It is rare in the pediatric population. The tumor does not respond well to chemotherapy or irradiation. Complete surgical resection offers the best chance for a cure. Most studies have demonstrated poor prognosis of this tumor, if it is >5 cm. The literature suggests that local recurrence and distant metastasis are not uncommon even with wide resection and that late recurrence and metastasis commonly occur. This case report discusses CSS in the jaw of a pediatric patient. To our knowledge, this is the only case of CSS of the jaw.
