Trigeminal trophic syndrome simulating rodent ulcer basal cell carcinoma: a new clinico-dermoscopic approach

Abstract Trigeminal trophic syndrome is an uncommon cause of facial ulcers, that affects the sensitive area of the trigeminal nerve. We present the case of an 84-year-old patient with ulcerated facial trigeminal trophic syndrome, and report the development of a clinico-dermoscopic approach for his clinical examination. The value of this model for the diagnosis of facial ulcers suspected to be a rodent ulcer basal cell carcinoma is suggested.
