Solitary fibrous tumour of the major salivary glands.

We report four cases of solitary fibrous tumours which involved the parotid (two cases), submandibular, and sublingual glands of two men and two women ranging in age from 46 to 81, mean 66 years. The tumours presented as painless, firm masses which involved the substance of the salivary gland in each case. All have had an uneventful clinical course after local excision. Awareness of this entity is important to avoid confusion with haemangiopericytoma.
