Topical Crisaborole for the Treatment of Recalcitrant Palmoplantar Pustulosis: A Case Series.
Palmoplantar pustulosis (PPP) is a chronic, relapsing disease with sterile pustules involving the palms and soles. The pathogenesis of PPP remains unclear and there is currently no standard treatment. We present three cases of recalcitrant PPP treated with topical 2% crisaborole cream in our clinic from October 2024 to February 2025. All of the patients had received skin biopsy to prove their diagnosis and had been treated with various treatments with limited response. After 4 weeks of topical crisaborole, their palmoplantar pustulosis area and severity index decreased from 7.2 to 2.8, 9 to 1.8, and 28.4 to 0, respectively. Given that PPP involves the skin locally, an effective topical treatment may provide a convenient, inexpensive alternative for such patients. The positive response of topical crisaborole observed in our cases also echoes the efficacy of apremilast, a systemic phosphodiesterase 4 (PDE4) inhibitor which successfully treated PPP in other reports, highlighting the potential role of PDE4 in the pathophysiology of PPP. Further studies are needed for a more comprehensive evaluation.
期刊介绍：
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
