Chondrodermatitis nodularis helicis (CNH) is a benign auricular disease whose differentiation with nonpigmented tumors is mandatory. Clinical characteristics of CNH are well known, but there is no information about the dermoscopic features that could help differentiate CNH from squamous cell carcinoma and other non-melanoma skin cancers. To describe the dermoscopic appearance of CNH and to formulate a differential diagnostic model, we conducted a retrospective, single center, observational dermoscopic study on a sample of 189 biopsy-proven lesions: 25 CNH; 26 squamous cell carcinomas; 62 basal cell carcinomas and 76 other benign and malignant tumors. Univariate and multivariate analyses were conducted by logistic regression. The most significant dermoscopic finding for CNH was a peculiar global configuration (daisy pattern), consisting of white thick lines, radially arranged, converging to a central rounded yellow/brown clod (an erosion covered by keratin or sero-crust). This pattern achieved 92 and 98% of specificity for discriminating CNH with squamous cell carcinoma and basal cell carcinoma, respectively. In conclusion, dermoscopy is valuable for the diagnosis of CNH as a first screening tool because of a consistent global dermoscopic configuration (daisy pattern), consisting of radially arranged white thick lines surrounding a central rounded yellow/brown clod.

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.

Herein, we describe a patient with lesions of cutaneous herpes simplex virus 1 (HSV-1) infection over the knuckles of both hands in the context of an outbreak among boxers. Interestingly, the infection had an unusually long duration (4 weeks), and was not acquired directly through skin-to-skin contact, as it usually does among athletes (herpes gladiatorum). In our case, transmission was acquired through the use of shared boxing gloves contaminated by HSV-1. To the best of our knowledge, herpes gladiatorum, or wrestler's herpes, has not been described previously in boxers and infection over the knuckles is not commonly reported.
