The Rash After The Remedy, Elaine Chen, Md

Books, Presentations, Posters, Etc.

Introduction: Trimethoprim/sulfamethoxazole (TMP/SMX) is a widely prescribed and generally well-tolerated antibiotic. Cutaneous reactions occur in up to 4% of patients, including morbilliform rash, urticaria, DRESS, Stevens-Johnson syndrome, and toxic epidermal necrolysis. More rarely, TMP/SMX can trigger leukocytoclastic vasculitis (LCV), a small-vessel vasculitis characterized by neutrophilic infiltration, fibrinoid necrosis, and leukocytoclasia. LCV typically manifests as palpable purpura on dependent areas. While often skin-limited, systemic involvement may occur. We present a case of TMP/SMX-induced LCV with multi-organ features. Case description: A 53-year-old healthy male presented to urgent care with dysuria. Urine culture grew pan-sensitive E. coli, and he completed a 7-day course …

Dermal: A Multi-Input Deep Learning Model For Improving Access To Dermatological Screening, Aubreye Freeman

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, …

Cutaneous Rosai-Dorfman Disease Misdiagnosed As Granulomatous Dermatitis: A Diagnostic Pitfall, Sri Naidnur, Jamie Hedrick, Smaran Marupudi, Kara Asbury, Kelly Maedo, Bryan Gammon, Rick Lin

School of Medicine Publications

Cutaneous Rosai-Dorfman disease (CRDD) is an uncommon non-Langerhans cell histiocytosis that may occur without systemic involvement and lacks specific clinical features. We report a 17-year-old female with a slowly enlarging chest lesion initially diagnosed as granulomatous dermatitis on a 4-mm punch biopsy. The lesion was treated as an inflammatory process without improvement. Complete excision revealed a multinodular dermal and subcutaneous infiltrate of large histiocytes demonstrating emperipolesis, confirming CRDD. Systemic evaluation was negative. The initial limited biopsy did not capture defining features, delaying diagnosis.

Persistent nodular lesions that fail to respond to therapy should prompt reconsideration and more representative tissue sampling. …

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Tinea Corporis, Braden Van Alfen, Navya Peddireddy, Marshall Hall, Henry Lim, Christian Scheufele, Garrett Furth, Dustin Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Tinea corporis is a common superficial fungal infection caused by dermatophytes. It typically presents as well-defined, pruritic, annular papules and plaques with central hypopigmentation. The differential diagnosis includes pityriasis rosea, nummular dermatitis, plaque psoriasis, tinea versicolor, granuloma annulare, and discoid lupus. This article compares different presentations of tinea corporis in various skin types as classified by the Fitzpatrick scale. Recognizing varying presentations of tinea in patients of different skin tones will aid in early and appropriate diagnosis and treatment.

Presentations Of Cutaneous Disease In Various Skin Pigmentations: Keratosis Pilaris, Henry Lim, Reem Ayoub, Madelyn Richards, Marshall Hall, Christian Scheufele, Dustin Wilkes, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Keratosis pilaris (KP) is a common benign disorder involving hyperkeratosis of the skin. It is associated with other common dry skin disorders such as atopic dermatitis and ichthyosis vulgaris. Lesions are clinically characterized as symmetrically distributed, monomorphic, folliculocentric, hyperkeratotic papules with a variable degree of perifollicular erythema. The appearance can be likened to spikey bumps that are commonly located on the arms, legs, and buttocks. Awareness of KP is important as every primary care clinician will see patients with this disorder. Identification can support the diagnosis of other associated skin diseases. Education about KP and its treatment may alleviate psychological …

The Efficacy Of The Fitzpatrick Scale In Clinical Practice, Dana Olsen, Cecilia Nguyen, Marshall Hall, Michael Carletti, Stephen E. Weis

HCA Healthcare Journal of Medicine

Many skin diseases can manifest differently depending on the pigment of one’s skin. The Fitzpatrick scale is a classification of phototypes (I-VI) that categorizes patients' skin based on its ability to tan and burn. Even though it is a simple questionnaire, the Fitzpatrick scale has numerous criticisms due to its dependence on patients’ self-perception, variability in how questions are asked, limited range, and the underestimation of the risk of skin cancers. Alternatives to the Fitzpatrick scale include the melanin index, pigment protection factor, a visual color scale, and using artificial intelligence along with existing or new scales. Having a more …

Late-Career Transitions From Private Practice To Academic Dermatology: Financial Drivers, Professional Rewards, And Practical Steps, Joshua R. Jennings, Thomas Helm, Jeremy D. Jackson, Robert T. Brodell, N A

School of Medicine

Independent practice dermatology once promised near-total clinical autonomy and robust profit margins, yet more and more dermatologists have been leaving their “private” practices and contemplating a mid- or late-career move to academia [1]. Openings are available! Over the last 25 years, many academic health centers have evolved to engage clinician educators in support of their educational mission, which requires more clinical rotations for larger student bodies and to provide income to offset losses in research support [23, 39]. Leaving private practice is neither anecdotal nor sentimental; it reflects quantifiable changes in reimbursement, overhead, and the …

Iatrogenic Ptosis Mimicking Cranial Nerve Iii Palsy Following Cosmetic Botox Injection: A Case Report, Moath Alshanqity, Lujain Filimban, Sadaqah Wazzan

Saudi Toxicology Journal

We present a 40-year-old female who developed iatrogenic ptosis mimicking cranial nerve III palsy after undergoing a cosmetic treatment to treat periorbital hyperpigmentation. Within 48 hours of receiving what was believed to be tranexamic acid (TXA) injections, the patient developed isolated left ptosis and generalized headache. Stroke, cerebral venous thrombosis (CVT), subarachnoid hemorrhage (SAH), and cranial nerve injury were among the differential diagnoses upon presentation. No insult to the central nervous system was found during the initial workup, which included neuroimaging. Although TXA was initially suspected due to its prothrombotic potential and the patient’s history of pulmonary embolism, it has …

Dementia Incidence In Patients With Prurigo Nodularis: An Observational Retrospective Cohort Study, Madison P. Olexson, Ana Ormaza Vera, Chunghwan Ro, Clinton W. Enos

Department Dermatology Faculty Publications

[Introduction] Prurigo nodularis (PN) is a chronic neuroinflammatory dermatosis of unknown etiology characterized by severely pruritic, symmetrically-distributed nodules with a negative impact on quality of life [1]. While some consider PN a primary idiopathic disorder, it often arises as a secondary manifestation of underlying conditions, including atopic dermatitis (AD), chronic kidney disease (CKD), human-immunodeficiency-virus (HIV), and thyroid disorders [2]. Although patients with PN are at higher risk for psychiatric comorbidities including depression, anxiety, and suicidal ideation [3] research which investigates associations between PN and neurodegenerative disorders is limited [4]. Moreover, emerging evidence implicating sustained systemic inflammation, characteristic of psoriasis and …

Central Centrifugal Cicatricial Alopecia In Pediatric Patients: A Retrospective Analysis, Radhika Gupta, Nikhita Perry, Noelle Desir, Iain Encarnacion, Jonathan Miles, Susan Taylor, Michelle Oboite, Temitaya Ogunleye

Department Dermatology Faculty Publications

[Introduction] Central centrifugal cicatricial alopecia (CCCA) is a scarring alopecia that predominantly affects middle-aged women of African descent.¹ It begins at the vertex scalp and expands centrifugally, and given that symptoms may be absent, many patients have scarring at presentation. CCCA is primarily described in adult populations, with limited reports of CCCA in children.²^-⁴ We aimed to characterize demographics, clinical findings, and histological features among pediatric patients with CCCA to facilitate earlier diagnoses, prior to irreversible alopecia.

A Case Of Median Raphe Cysts In 8-Year-Old Male, Christina Guo, Marshall Hall, Garrett Furth, Henry Lim, Olivia Gruver, Dustin Wilkes, Stephen E. Weis

Background: The median raphe cyst is a rare, benign, congenital condition characterized by small, fluid-filled cysts that develop along the ventral midline of male external genitalia. These cysts are usually asymptomatic during infancy and childhood but tend to grow in size as the patient grows. These can become cosmetically concerning or symptomatic due to swelling, irritation, and discomfort. They may also present social and psychological stress to patients and families. We present a case of median raphe cysts in an 8-year-old male.

Case Presentation: An 8-year-old male without a prior medical history who presented to dermatology for penile lesions. He …

Evaluating The Alt-70 Model For Cellulitis Management In The Emergency Department, Marshall Hall, Paige Loux, Henry Lim, Jeffrey Durbin, Garrett Furth, Olivia Gruver, Christina Guo, Dustin Wilkes, Michael Carletti, Stephen E. Weis

North Texas GME Research Forum 2026

Background: Cellulitis is a common skin infection that classically presents with unilateral lower extremity erythema, swelling, and pain. The diagnosis is made clinically. Many conditions may mimic cellulitis that are collectively referred to as “pseudocellulitis.” These include stasis dermatitis, deep vein thrombosis, atopic dermatitis, psoriasis, and gout. The Alt-70 model is a validated clinical prediction tool for differentiating cellulitis from pseudocellulitis. It is unclear if it is utilized or if it has changed clinical practice in the emergency department setting.

Methods: This was a retrospective chart review study utilizing the HCA Healthcare Data Warehouse. The Alt-70 model was applied using …

Excision Followed By Standing Cone Deformity Repair Is Tissue Conservative, Henry Lim, Christian Scheufele, Marshall Hall, Stephen Weis, Dustin Wilkes

North Texas GME Research Forum 2026

Introduction Elliptical excisions are the most common method to treat benign and malignant tumors in dermatologic surgery. This standardized design is traditionally 3 to 4.5 times longer than the excisional width to prevent unsightly protrusions of skin after primary closure, known as “standing cone,” “Burow’s triangles” or “dog ear” deformities. This results in a scar significantly longer than the original tumor that may be less easily concealed.

Objective To compare the final repair length of a tissue conservative method to remove skin tumors and close resultant defects against predicted repair length of traditional elliptical excision.

Methods Eighteen cases are presented …

North Texas GME Research Forum 2026

Background: Inpatient dermatology is an important yet evolving field. There has been a linear decrease in the number of dermatologists providing inpatient care and in the number of medical centers with an inpatient dermatology service. Medical centers with inpatient dermatology services are unevenly distributed geographically, with most in larger metropolitan areas. There is still a great need for dermatologic expertise in the inpatient setting. We aim to examine the utility of the dermatologic consult service, including the most common chief complaints and conditions that prompted consultation over four months at Medical City Fort Worth.

Methods: This was a retrospective chart …
