Successful Treatment of Tinea Versicolor With Salicylic Acid 30% Peel

Abstract

BACKGROUND: Tinea versicolor is a common superficial fungal infection caused by Malassezia species. It typically affects the trunk and proximal upper extremities and is treated with topical or oral antifungal medications. Treatment may be limited by patient preference or logistical constraints, especially in cases of extensive cutaneous involvement, where topical application may be challenging. CASE PRESENTATION: An 18-year-old active duty female with extensive tinea versicolor, likely precipitated by military training in hot and humid conditions, presented to the dermatology clinic. Given the patient's inability to consistently apply topical treatments during military activities and the limited efficacy of oral antifungals, the patient underwent in-office treatment with a salicylic acid 30% peel. Two peels were administered 10 days apart. At 3 weeks posttreatment the arm lesions were no longer evident and there was significant improvement of the lesions on her back. Incidental improvement in acne vulgaris was also noted. CONCLUSIONS: This case highlights the potential use of a salicylic acid 30% peel as an effective in-office treatment for tinea versicolor, particularly in patients who face challenges with topical medication adherence. The peel also offers additional benefits for patients with concomitant acne.
