Implementing A Specific And Standardized Grading Scale For Therapeutic Injection Site Reactions To Improve Adverse Event Reporting, Priya Kale, Kavita Sarin

Research Colloquium

Up to 15.5% of patients taking biologic medication experience injection site reactions (ISRs) leading to morbidity, early discontinuation, and reduced treatment compliance. As biologic medications are increasingly used to treat chronic inflammatory conditions, including psoriasis and atopic dermatitis, there needs to be an improved understanding of ISRs. However, current methods of grading ISRs are nonspecific and unstandardized leading to a lack of understanding of medication-specific ISRs and ambiguity in perceptions of treatment tolerability. Here we aim to develop a standardized ISR grading scale for use in clinical trials. A scoping review was performed to evaluate current ISR grading scales and …

Regional Disparities In The Diagnostic Age Of Skin Carcinomas: An Analysis Of The Rio Grande Valley, Miguel A. Lopez, Natasha Quailes, Elias Arellano Villanueva, Maria Villegas

Research Colloquium

The Rio Grande Valley (RGV) is a region of South Texas with limited dermatologic diagnostic data, particularly among non-melanoma skin carcinomas. The rising rates of chronic conditions and mortality can be attributed to the limited access to healthcare in the region, with skin conditions taking less priority in patients with numerous comorbidities. Data on the age of diagnosis for skin carcinomas between 1995-2019 for Hispanic and non-Hispanic individuals was obtained from the Texas Cancer Registry. It is important to note that the TCR considers primary skin cancers, such as basal and squamous cell carcinoma coded as C44.0-C44.9, as non-reportable cases. …

An Analysis Of The Diagnostic Age Of Skin Carcinomas Across Central Texas, Miguel A. Lopez, Natasha Quailes, Elias Arellano Villanueva, Hamaad Gohar, Maria Villegas

Research Colloquium

Patients seeking healthcare in medically underserved regions often require travel to larger metropolitan hubs across the state of Texas. The Rio Grande Valley (RGV) is home to many such patients who often travel to central Texas for care, which compounds expense and inconvenience. Pockets of central Texas have been reported to have an increased number of dermatologists per 100,000 people. Bexar county ranks among the five most populous counties in the state, with increased access to dermatologic care compared to nearby regions. Using data from the Texas Cancer Registry, this project aims to identify the mean (M) age of diagnosis …

Efficacy And Safety Of Rigosertib In Patients With Recessive Dystrophic Epidermolysis Bullosa-Associated Advanced/Metastatic Cutaneous Squamous Cell Carcinoma, Martin Laimer, Andrew P. 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 …

Department of Dermatology and Cutaneous Biology Faculty Papers

Hypertension has been previously associated with higher intraoperative bleeding risk in patients undergoing Mohs micrographic surgery. However, the risks of common postoperative Mohs micrographic surgery complications have not been substantiated by large studies. Our study aimed to assess the risks of common Mohs micrographic surgery complications for patients with hypertension utilizing the TriNetX database, a global health records database encompassing over 105 million patients' data, from January 2009 to January 2024. After 1:1 propensity score matching for age, sex, race, diabetes, nicotine dependence, obesity, and anticoagulant use, the final analysis included 80,739 patients in each cohort of patients with hypertension …

Usage And Behavioral Data Of Consumers Using Hair Dye Products Containing 2-Methoxymethyl-P-Phenylenediamine, Monika Kock, Carsten Goebel, Lidia Mihailescu, Maike Seib, Agnieszka Malesa, Anthony Gaspari, Brunhilde Blömeke

Department of Dermatology and Cutaneous Biology Faculty Papers

The potent sensitizer PPD is considered a key sensitizer in hair dye contact allergy. Modification of its molecular structure to 2-methoxymethyl-p-phenylenediamine (ME-PPD) reduces its skin sensitizing potency. We investigated the usage, behavior, and tolerance profile of ME-PPD-containing professional hair color products in a specifically tailored proactive market surveillance program in hairdresser salons across 5 countries. Hairdressers completed record cards for their clients, which were evaluated at the end of the program. 497 individuals received in total 2461 hair color treatments with ME-PPD-containing hair color. Feedback on compatibility was provided for 194 individuals: 6 individuals reported intolerance reactions, which were assessed …

Advancements In Diversity In Dermatology: A 5-Year Retrospective Analysis Of Racial And Ethnic Trends In U.S. Dermatology Residency Programs (2020-2024), Devin Barzallo, Afua Ofori-Darko, Larissa De Souza, Precious Nwanwa, Timmie Sharma

Student Scholarship

Diversity in residency programs is important for achieving health equity. Although targeted initiatives have led to some progress, dermatology residency trainees do not proportionally reflect the growing diversity of the U.S. population. We analyzed data from the Association of American Medical Colleges on residents from 2020 to 2024 to evaluate evolving diversity trends.

Actin Up And Factor’D In: ​ A Pediatric Spindle Cell Lesion Case Presentation, Michael Higham, Stephanie Campbell, Naomie Jean, Amanda Killeen

School of Podiatric Medicine Publications

Introduction: Solitary spindle cell nodules on the foot in pediatric patients are rare and diagnostically challenging. Dermatofibroma (benign fibrous histiocytoma), a common adult dermal lesion, is infrequently observed in children under 18.

The spectrum of pediatric spindle cell tumors includes reactive entities like nodular fasciitis and dermatomyofibroma, benign neoplasms such as myofibroma, and malignant tumors including spindle cell rhabdomyosarcoma, fibrosarcoma, and dermatofibrosarcoma protuberans (DFSP). Accurate differential diagnosis is essential, as DFSP requires wide excision or Mohs surgery to reduce recurrence risk.

Methods (Case Presentation): An 11-year-old boy presented with a one-year history of a non-healing lesion on the heel, initially …

A Comprehensive Narrative Review Of The Challenges Surrounding Cutaneous Scc., Sarah C Beach, Austin S Cusick, Aaron S Farberg, Shannon C Trotter

Ambulatory and Primary Care Articles

Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer (NMSC) and is predominantly found in the head and neck region. With an annual increase in NMSC diagnoses, cSCC presents significant diagnostic and therapeutic challenges. This review discusses the many risk factors for the development of cSCC, outlines the criteria for defining high-risk cSCC, and examines treatment approaches of these tumors based on risk stratification. While most cSCCs are treatable with surgical excision, approximately 5% metastasize, with head and neck cSCC showing poor prognosis once metastasis occurs. High-risk cSCCs, which are more likely to recur or metastasize, …

Lichen Planopilaris With Pili Torti And Ectodermal Dysplasia: A Hair Curling Case Report, Collins Langley, Elena Plakotaris, Nicole E. Rogers

School of Medicine Faculty Publications

Introduction: Lichen planopilaris (LPP) is a well-known cicatricial alopecia with a frontal fibrosing variant. LPP has a prevalence rate of 13.4 per 100,000 persons. It is understood that LPP favors the female populations. What is not commonly known is that LPP can be preceded by other signs and symptoms such as pili torti. Case Report: We present a case report of a 70-year-old female whose initial flare of LPP was preceded by a flare of pili torti. This patient's case is also complicated by her history of ectodermal dysplasia. She experienced progressive itching, shedding, and mid-scalp hair loss along with …

Disseminated Diaper Dermatitis With Concomitant Body Rash: A Case Report., Catherine F Alapatt, Eileen Condren, Tanya Kadrmas-Iannuzzi

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Diaper dermatitis is a rash typically localized to the genital area and may have various etiologies, including irritant and allergic contact dermatitis. In most cases, it resolves on its own with minimal to no medical intervention, and when treatment is necessary, it usually responds promptly. Here, we present a prolonged case of diaper dermatitis accompanied by a nearly full-body rash that was resistant to initial treatment with steroids, antibiotics, and antifungals.

Spontaneous Tumor Regression And Immunotherapy Response Demonstrate Clonal T-Cell Expansion In Merkel Cell Carcinoma, Patrick Hallaert, John W Roman, Mairead Baker, Natasha T Hill, Jennifer L Marte, James L Gulley, Nicholas Logemann, Courtney W Hudgens, Alexandre Reuben, Isaac Brownell

Faculty, Staff and Student Publications

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin cancer that is responsive to immune checkpoint inhibitors (ICI). On rare occasion, MCC spontaneously regresses. It is speculated that this regression occurs when biopsy-induced antigen shedding precipitates an immune response. Here, we demonstrate the activation of an adaptive immune response in a patient whose tumor underwent spontaneous regression after biopsy. To evaluate the tumor immune microenvironment during regression, we performed quantitative immunohistochemical analysis and T-cell receptor (TCR) sequencing. Relative to baseline, the regressing tumor showed evidence of an activated cytotoxic T-cell response together with increased TCR clonality, greater representation …
