Atrophying Pityriasis Versicolor: A Rare Presentation of a Common Dermatological Disorder and Literature Review

Pityriasis versicolor is a superficial fungal infection of the skin caused by fungi of the genus Malassezia. Typically, patients present with well-defined, hypopigmented, scaly macules, or patches over seborrheic areas. However, rare presentations include papular, confetti-like spots, and folliculocentric, atrophic, and inverse forms. Diagnosis may be established clinically with the help of noninvasive diagnostic tools such as dermoscopy, Wood's lamp, and direct microscopic examinations. However, skin biopsies are imperative in equivocal cases. To date, 34 cases have been reported. This study presents a rare presentation of atrophying skin lesions in a patient with pityriasis versicolor.
