Abstract

Tinea versicolor (TV) is a common fungal skin disease caused by the Malassezia species. This disease usually presents as hypopigmented- or hyperpigmented coalescing scaly macules, papules, patches or plaques on the trunk and upper arms. Herein, we report a rare clinical manifestation of TV in a 29-year-old man presenting with marked follicular, erythematous, and hyperkeratotic papules on the trunk with erythematous scaly macules and patches on the upper extremities with intermittently spared skin. We initially suspected pityriasis rubra pilaris, however, skin biopsy results and mycological examination revealed TV. Polymerase chain reaction-based sequence analysis revealed Malassezia globosa. The patient was successfully treated with oral itraconazole and topical terbinafine.
