Trigeminal trophic syndrome (original) (raw)

Trigeminal trophic syndrome is a rare disease caused by the interruption of peripheral or central sensory pathways of the trigeminal nerve. A slowly enlarging, uninflammed ulcer can occur in the area that has had trigeminal nerve damage; including but not limited to the cheek beside the ala nasi. These sores affect the skin supplied by the sensory component of the trigeminal nerve. Similar lesions may also occur in the corners of the eyes, inside the ear canal, on the scalp or inside the mouth. Sixty cases were reported from 1982 to 2002.
