Fibrosarcoma of the ethmoid.

Fibrosarcoma may involve the ethmoid sinus by extension from the maxillary antrum or, more rarely, arise as a primary neoplasm. A case of a well differentiated primary fibrosarcoma of the ethmoid sinuses is reported which presented in a 24-year-old male. The tumour was treated by wide local resection. From a review of similar cases in the literature together with their treatment modalities and outcome, it is concluded that wide local resection is the treatment of choice.
