Atrophying pityriasis versicolor: A rare variant with review of literature

摘要

Pityriasis versicolor is a superficial fungal infection caused by Malassezia species and characterized by roundish to oval maculopatches varying in color from hypopigmentation to red to hyperpigmentation. The typical locations usually involved are the upper trunk, neck, and upper arms. However, rare cases present with atrophic patches, which might be misdiagnosed as other diseases that cause skin atrophy, such as atrophoderma of Pasini and Pierini. We herein report a case of pityriasis versicolor with cutaneous atrophy.
