Summary

Trigeminal trophic syndrome causes skin ulcers from self-manipulation due to trigeminal nerve damage. This case highlights brain stem infarction as a cause and emphasizes neurological exams for diagnosis.

Area of Science:

  • Neurology
  • Dermatology

Background:

  • Trigeminal trophic syndrome (TTS) is a rare condition characterized by skin ulcers.
  • It arises from damage to sensory trigeminal nerve fibers or nuclei, leading to altered sensation.

Observation:

  • Patients with TTS often report self-inflicted manipulation (picking, rubbing, scratching) of affected facial areas.
  • This manipulation is driven by sensory disturbances like hypoesthesia, paresthesia, or pain.

Findings:

  • This report details a patient who developed TTS as a consequence of brain stem infarction.
  • Diagnostic approaches, including scrape cytology to exclude skin cancers, are discussed.

Implications:

  • Neurological examination is crucial for identifying trigeminal hemi-anesthesia, aiding TTS diagnosis.
