title: Tinea pedis presenting as asymmetric purpuric papules on the sole of the foot: a case report.
abstract: In this report we describe a unique case of tinea pedis. A 29-year-old man presented with a 3-day history of asymptomatic purpuric papules predominantly on his left foot. Potassium hydroxide preparation demonstrated fungal hyphae and culture yielded Trichophyton mentagrophytes. This patient presented unusually with purpuric papules, unlike the three commonly described types of tinea pedis. Given the morphology, positive potassium hydroxide slide preparation, T. mentagrophytes on fungal culture and clinical response to ketoconazole cream, we conclude that this represents a unique variant of tinea pedis. We recognize that even common dermatological diagnoses can have unique presentations, and it is important for clinicians to maintain a broad differential for new dermatologic cases.
