A new meaning to "picking your nose": The first use of N-acetylcysteine to successfully treat trigeminal trophic syndrome.

Trigeminal trophic syndrome (TTS) is a rare neurological condition characterized by self-induced injury to the face in the distribution of the trigeminal nerve. Chronic scratching or picking cause ulceration, scarring, and tissue loss. TTS typically occurs following damage to the trigeminal nerve, often from surgical procedures, trauma, or stroke. We present a case of trigeminal trophic syndrome in an elderly lady who successfully responded to oral N-acetylcysteine. An increased awareness of this rare syndrome and potential treatment options will encourage a prompt diagnosis and possibly prevent permanent disfiguration.

Topical treatments in dermatology.
