Chondromyxoid fibroma of the petrygo-palatine space.

A patient who for five years had obstinate unilateral facial pain, difficult to interpret, was found to have an expanding process in the left retromaxillary space. Histological examination of a biopsy specimen revealed chondromyxoid fibroma. This tumour is rarely seen in the bones of the face and has never before been described in this area. The clinical and histological findings are described and discussed.
