Isi artikel

A 66-year-old man presented to a dermatologist with a pruritic, erythematous, scaly, and mildly hyperpigmented rash of 2 weeks' duration that involved the scrotum and both inguinal creases (Panel A). Under examination with ultraviolet A light from a Wood's lamp, the rash exhibited coral-red fluorescence (Panel B), a finding pathognomonic for erythrasma. This common disorder results from overgrowth of Corynebacterium minutissimum in the superficial stratum corneum of moist intertriginous and interdigital regions. The coral-red fluorescence is a result of the production of coproporphyrin III by C. minutissimum, and it helps to distinguish this disorder from dermatophytoses, candidal intertrigo, and psoriasis. Skin scrapings show gram-positive filamentous rods, which may be helpful in assessing for concurrent dermatophytic and candidal infection. After a short course of oral erythromycin, this patient's rash and pruritus resolved completely.
