Varied Presentations of Tinea Versicolor: Case 3 Papulosquamous Tinea Versicolor

A palpable papulosquamous, arciform chronic eruption had been present in a 70-year-old man for many years. The asymptomatic rash was in a "mantle" distribution-- across the upper shoulders, neck, and back. A potassium hydroxide (KOH) preparation demonstrated the short, clustered hyphae and spores of Malassezia furfur. The condition responded to topical econazole. It is uncommon for tinea versicolor to be palpably and overtly scaly. However, given the eruption's distribution, the presence of spores as well as hyphae on the KOH evaluation, the positive therapeutic response to appropriate treatment, and the prevalence of this yeast infection, the diagnosis of tinea versicolor was undoubtedly correct. The differential diagnosis included epidermal nevus and tinea corporis. Epidermal nevus has a significant intradermal component and is congenital, whereas tinea versicolor is epidermal and acquired. Tinea corporis is typically acute in onset and more inflammatory, but it can be chronic.
