Successful Treatment of Pityrosporum Folliculitis with Isotretinoin
Journal Title: Journal of Dermatology Research - Year 2024, Vol 5, Issue 3
Abstract
Pityrosporum Folliculitis (PF) is a condition characterized by pruritic 1-2 mm monomorphic follicular papules and pustules on the upper back, chest and shoulders. PF is caused by overgrowth of Malassezia furfur, a commensal yeast found in the infundibulum of sebaceous glands and may be exacerbated by immunosuppression, occlusion and sweating. We present a case of PF with inadequate response to both topical and systemic antifungal therapy, which completely cleared on isotretinoin. A 44-year-old male with no significant medical history presented for evaluation of a pruritic rash on his chest and back which had been present intermittently for 2 years and was inadequately controlled with use of betamethasone valerate 0.1% cream and then ketoconazole 2% cream. Examination of the back revealed a large, slightly raised erythematous plaque with scale and scattered follicular papules and pustules (Fig. 1).
