Keratocystoma of the parotid gland: a case report and review of previous publications.

Keratocystoma is a rare benign tumour of the salivary glands. We report a patient who presented with a mass in the left parotid gland that was treated by subtotal parotidectomy and he was free of recurrence seven years later. After histological and immunohistochemical examinations we identified a keratocystoma.
