Trigeminal Trophic Syndrome

Trigeminal Trophic Syndrome (TTS) is a rare, well-documented neurocutaneous condition characterized by the triad of paresthesia, analgesia, and ulcerations caused by self-manipulation, most commonly affecting the ala nasi. It typically arises following injury to the trigeminal nerve, either centrally or peripherally. We report the case of a 75-year-old woman who developed TTS following a cerebral stroke. Initially, her symptoms were misinterpreted as a psychiatric disorder, but the diagnosis of TTS was ultimately made based on the combination of prior trigeminal nerve injury and the classical symptom triad. This case highlights the diagnostic challenges of TTS and emphasizes the need to consider neurological etiologies in patients with atypical facial ulcerations.
