[Trigeminal trophic syndrome--a tough diagnostic nut to crack].

Trigeminal trophic syndrome (TTS) is a rare but well-described syndrome consisting of the triad: paraesthesia, anaesthesia and crescent-shaped ulceration of the ala nasi. We report a case of a 62-year-old woman presenting with TTS after operative excision of an acusticus neurinoma. She attended several different specialized physicians and multiple biopsies were performed before attention was brought to the syndrome due to a history of trigeminal nerve damage combined with the aforementioned triad.
