He described the first case of swimmer's itch to occur in exposed skin[10] and described the first case of herpetic paronychia occurring in an atopic patient while on isotretinoin therapy for acne.[11] He confirmed that the incidence of epidermolytic hyperkeratosis is higher in association with dysplastic nevi than in ordinary melanocytic nevi and may serve as a marker for nevus with architectural disorder.[11]
