Description
Summary:Trigeminal trophic syndrome occurs secondary to trigeminal nerve injury, leading to anaesthesia and paraesthesia, with consequent vigorous facial skin manipulation and lesion production, simulating other facial diseases such as ulcerative discoid lupus erythematosus, tumours and other artificially produced lesions. Ulceration and destruction of the ala nasi is a typical feature besides scratching end excoriations in the cutaneous segment affected. In this series, we present the features of five patients with trigeminal trophic syndrome, highlighting possible confusion with cutaneous lupus. Differential diagnoses, including discoid lupus erythematosus, are discussed, as well as possible treatment modalities.
