Chronic balanitis: an unusual localisation of necrobiosis lipoidica.

Abstract

CASE REPORT A 26 year old male veterinarian consulted us for a mildly scaly patch with irregular, well delimited active borders localised on the dorsal surface of the shaft (fig). The lesion was about 1-5 x 2 cm in size. A smaller papular lesion (0-5 x 1 cm) was also present nearby. These totally asymptomatic lesions had appeared 15 days before. There were no lesions in the groin or elsewhere. Microscopic examination of the scales from the margins of the lesion in 10% KOH preparation showed multiple septate hyphae. Culture in Sabouraud's media revealed growth of colonies identified as Microsporum canis. Direct microscopic examination as well as culture from scrotum, crural folds, palms, and fingernails were negative. Therapy with econazole nitrate cream applied twice a day for 2 weeks induced a complete healing of the lesions. A follow up skin examination after 1 month was negative for dermatophytosis.
