The early effects of intravenous L-propionyl carnitine on ulcerative trophic lesions of the lower limbs in arteriopathic patients: a controlled randomized study.

Postencephalitic trophic ulcer is an ulceration of the nose similar to trigeminal trophic lesions, and has been reported following epidemic encephalitis and herpes zoster of the trigeminal nerve.

Trigeminal trophic lesions (also known as "Trigeminal trophic syndrome") are a cutaneous condition caused by the interruption of peripheral or central sensory pathways of the trigeminal nerve that result in a slowly enlarging, uninflammed ulcer on the cheek beside the ala nasi.
