BACKGROUND: Psoriasis of the intertriginous, anogenital, and facial regions remains a therapeutic challenge, with current algorithms lacking a topical agent that exhibits both high efficacy and minimal side effects. OBJECTIVE: To assess the safety and efficacy of crisaborole 2% ointment-a nonsteroidal phosphodiesterase 4 inhibitor-in the treatment of intertriginous, anogenital, and facial psoriasis. METHODS: A double-blind, randomized, vehicle-controlled trial was conducted in 21 participants. Participants were randomized 2:1 to receive 4 weeks of twice-daily treatment with either crisaborole 2% ointment (n = 14) or vehicle ointment (n = 7), followed by 4 weeks of open-label treatment with crisaborole 2% ointment. Disease severity was measured by using the Target Lesion Severity Scale (TLSS). RESULTS: After 4 weeks, participants in the crisaborole group demonstrated 66% improvement compared with 9% in the vehicle group (P = .0011). Participants in the crisaborole group continued to experience improvement through the open-label phase, demonstrating 81% lesional improvement by week 8, with 71% of these participants achieving clinical clearance. There were no adverse events. LIMITATIONS: The study was limited to a single tertiary care center and small sample size. CONCLUSION: Treatment with crisaborole 2% ointment was well-tolerated and led to clinical improvement in participants with intertriginous, anogenital, or facial psoriasis.
