BACKGROUND: Adalimumab is widely used for hidradenitis suppurativa (HS), but treatment durability varies and predictors of sustained benefit remain uncertain.

OBJECTIVE: To identify clinical and laboratory factors associated with adalimumab treatment durability in HS.

METHODS: We retrospectively studied 135 adults with HS who initiated adalimumab as first biologic therapy across three academic centers from 2013 to 2023. Outcomes were categorized as primary failure (12-24 weeks), secondary failure (24 weeks-2 years), or sustained response (>2 years) based on discontinuation for inefficacy. Predictors of treatment durability were evaluated using ordinal logistic regression.

RESULTS: In univariable analyses, Hurley stage 3, higher body …

Department of Dermatology and Cutaneous Biology Faculty Papers

Langerhans cell histiocytosis (LCH) is a rare malignancy marked by clonal proliferation of Langerhans cells, with BRAF V600E mutations identified in over 50% of the cases. BRAF inhibitors (BRAFi), such as dabrafenib, have shown efficacy in treating BRAF V600E-mutant LCH. However, BRAFi therapy is associated with cutaneous adverse effects, including the development of new melanocytic nevi, verrucae, and keratinocyte carcinoma (KC). This case report describes a 78-year-old woman with BRAF V600E-mutant LCH who developed multiple dermatologic side effects following dabrafenib salvage therapy. Seven weeks into treatment, the patient presented with eruptive palmoplantar nevi, verrucae, and a basal cell carcinoma (BCC). …

Occupational Epidemiology Of Acral Lentiginous Melanoma, Lily Guo, Robin Kikuchi, April W. Armstrong, Suephy C. Chen

Department of Dermatology and Cutaneous Biology Faculty Papers

Acral lentiginous melanoma (ALM) classically presents in glabrous skin. Some studies suggest an association between mechanical stress and ALM development. People working jobs with long periods of standing/walking may be exposed to near-daily mechanical stress. To investigate the relationship between occupation type and ALM development, we performed a retrospective cohort study using Optum’s Clinformatics Database (2007—2023). We compared the risk of ALM in adults with occupational data (n = 9,270,935). Retired patients had the highest prevalence (0.081) and incidence per 1,000,000 person-years (0.514, 95% confidence interval = 0.487—0.542) of ALM. We performed multivariate logistic regression, adjusted for demographics and insurance, …

Case description: A 37-year-old female with hemophagocytic lymphohistiocytosis presented with sudden onset hair loss that evolved over several hours during admission for neutropenic fever. Examination revealed a well-defined, tender, violaceous alopecic patch with intact follicular ostia (Fig 1). A punch biopsy showed ulcer with nonspecific changes. All fungal, bacterial, and mycobacterial stains were negative. During hospitalization, she was diagnosed with methicillin-resistant staphylococcus aureus (MRSA) bacteremia and discharged on intravenous daptomycin. She presented to the dermatology clinic 1 week later with worsening pain and hair loss, now with loss of follicular ostia.

Porokeratosis Ptychotropica Mimicking A Herpes Simplex Virus Infection, Erin R. Pomerantz, Jayci G. Rhein, Jason B. Lee, Sylvia Hsu

Department of Dermatology and Cutaneous Biology Faculty Papers

Introduction

Porokeratosis encompasses a group of skin disorders characterized by abnormal keratinization, with the defining histologic feature of cornoid lamellae, which are stacks of parakeratotic cells that overlie dyskeratotic keratinocytes. Several subtypes of porokeratosis have been identified, including disseminated superficial actinic porokeratosis, porokeratosis of Mibelli, linear porokeratosis, porokeratosis palmaris et plantaris disseminata, punctate porokeratosis, and porokeratosis ptychotropica (PP).¹ Although risk factors for other forms of porokeratosis, such as UV exposure, immunosuppression, and genetic predisposition, have been identified, PP remains less understood. Clinically, PP typically presents as hyperkeratotic, verrucous plaques found bilaterally in the gluteal cleft and buttocks.^{2, …}

Cd5 Expression In Ctcl And Its Implications For Anti-Cd5 Car T-Cell Therapy, Leena Wardeh, Madeline Williams, Courtney Prestwood, Zachary Wolner, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

Cutaneous T-Cell Lymphomas (CTCL) are a heterogenous group of T-cell malignancies in the skin and have poor treatment outcomes in advanced stages. CD5, a surface glycoprotein expressed on most mature T cells, has emerged as a promising target for chimeric antigen receptor (CAR) T-cell therapy in systemic T-cell lymphomas. However, its expression profile in CTCL and relevance for targeted therapy remain unclear. Notably, in CTCL, the cell surface expression of receptors, such as CD7 and CD26, tends to become downregulated on the surfaces of malignant T cells In this study, we analyzed single-cell RNA sequencing (scRNA-seq) data from patients at …

South, Elisabeth Mayr, Sophie Kitzmueller, Lauren Banner, Michael Alexander, Linda Hosler, Henry Yang, Matthew Parris, Meena Arora, Georg Zimmermann, Gregor Schweighofer-Zwink, Johann Bauer, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

BACKGROUND: Recessive dystrophic epidermolysis bullosa (RDEB) is an epithelial fragility disease primarily affecting the skin and is caused by variants in the COL7A1 gene. Individuals with RDEB are predisposed to develop highly aggressive cutaneous squamous cell carcinomas (SCCs) which are the most common cause of premature death. There is a lack of effective prevention or treatment options for patients with RDEB-SCC.

OBJECTIVES: To evaluate the antitumour activity and safety of the polo-like kinase-1 (PLK1) inhibitor, rigosertib, two investigator-initiated open-label, single-arm phase II studies were opened in Europe and the USA and enrolled five patients with RDEB diagnosed with locally advanced …
