Derms and Conditions

• Index of Suspicion is the Friend of the Clinician: Great Cases from the Northeast

  Index of Suspicion is the Friend of the Clinician: Great Cases from the Northeast   In this episode of Derms and Conditions, host James Q. Del Rosso, DO, welcomes Erik Domingues, MD, a dermatologist in Fall River, MA, to review 3 cases where cutaneous presentations led to unexpected findings or required creative treatment approaches.   The first case involves a 74-year-old man with diffuse granuloma annulare (GA). Although biopsy confirmed GA, the widespread involvement raised concern for an underlying condition. When standard therapy failed, Dr Domingues noted a cervical mass that proved to be an aggressive parotid carcinoma, detected earlier than it might have been without the skin eruption. The case highlights the need for thorough physical exams and clinical judgment when faced with atypical presentations.   They next consider a 34-year-old woman presenting with severe alopecia areata (AA). While her main concern was hair loss, Dr Domingues also observed long-standing facial vitiligo. She was started on ritlecitinib, approved for AA and under study for vitiligo, leading to complete scalp regrowth and substantial repigmentation of her vitiligo. The case highlights how treatment can address both immediate concerns and chronic disease burden, while also reminding clinicians that many patients remain unaware of newer therapeutic options.   The episode closes with a personal case: Dr Domingues’s 5-year-old son, who experienced a severe atopic dermatitis flare that stopped responding to crisaborole. Roflumilast 0.3% cream, approved for atopic dermatitis in patients 6 years and older at a lower concentration, was trialed off-label, producing rapid clearance and ongoing control with seasonal use. This case demonstrates how careful clinical judgment can guide effective off-label treatment.   Tune in to the full episode for practical pearls and real-world examples of clinical reasoning, autoimmune overlap, and innovative strategies for chronic skin disease.

• Getting the Upper Hand on CHE! Observations from a Principal Investigator

  In this episode of Derms and Conditions, host James Q. Del Rosso, DO, welcomes April Armstrong, MD, MPH, Professor and Chief of Dermatology at UCLA, to discuss chronic hand eczema (CHE) and the introduction of the first FDA-approved treatment developed specifically for this condition. The conversation begins with a review of CHE as a distinct clinical entity, highlighting its subtypes: irritant contact dermatitis, allergic contact dermatitis, atopic hand eczema, and the less common protein contact dermatitis. They highlight occupational exposures and daily “wet work” that increase risk, while Dr Del Rosso notes the challenge of overlapping subtypes in real-world patients. Practical considerations, such as glove selection and improving patient adherence, are also addressed. The discussion then turns to delgocitinib cream, the newly approved topical pan–JAK inhibitor for moderate-to-severe CHE. Dr Armstrong explains its mechanism of action, which targets the JAK-STAT pathway across multiple immune processes involved in different CHE subtypes. They note the significance of its approval without a boxed warning, contrasting it with other topical JAK inhibitors and providing context on evolving perspectives on JAK inhibitor safety. Clinical trial findings are discussed in detail, including meaningful improvements in itch, pain, and quality of life, along with the durability of response over time. Importantly, efficacy was observed across CHE subtypes, reflecting the drug’s utility across real-world patient heterogeneity. Adverse events were minimal, with no systemic safety signals observed. Tune in to the full episode to hear Dr Armstrong and Dr Del Rosso highlight the key factors of diagnosing and treating CHE, the clinical impact of delgocitinib, and how dermatologists are now better positioned to treat this commonly encountered yet difficult to manage condition.

• The Data Speaks for Itself: TYK2 Take 2 with Dr Andy Blauvelt

  In this episode of Derms and Conditions, host James Q. Del Rosso, DO, is joined by Andy Blauvelt, MD, to explore the mechanism, efficacy, and safety of deucravacitinib, the first FDA-approved tyrosine kinase 2 (TYK2) inhibitor for psoriasis. Dr Blauvelt begins by explaining how TYK2 inhibition differs from traditional JAK inhibition by targeting a more selective signaling pathway downstream of cytokine receptors. Unlike JAK1, JAK2, or JAK3, TYK2 is involved in a narrower range of cytokines, which may explain its distinct safety profile. Dr Del Rosso and Dr Blauvelt also clarify why deucravacitinib lacks the boxed warning seen with other oral JAK inhibitors. With allosteric binding at the TYK2 pseudokinase domain, deucravacitinib avoids cross-inhibition of other JAKs, making it more selective and potentially safer. Long-term data now supports this distinction: 5-year safety results show no increased risk of major adverse cardiac events, malignancy, or serious infections, with only a small, manageable signal for herpesvirus infections. The conversation turns to efficacy, which appears sustained over 5 years without antibody development, a potential advantage over biologics. Dr Blauvelt emphasizes its utility in high-impact areas such as the scalp, palms, soles, genitalia, and nails, and encourages systemic therapy even in patients with limited body surface area involvement when quality of life is severely affected. Tune in to the full episode to learn how deucravacitinib fits into the current psoriasis treatment algorithm, what sets TYK2 inhibition apart from other oral options, and how real-world data is shaping clinical confidence in this novel therapy.

• Detroit Has Motown, Motor Vehicles, and Some Challenging Dermatology Cases!

  In this episode of Derms and Conditions, host James Q. Del Rosso, DO, welcomes David Altman, MD, dermatologist at Midwest Center of Dermatology in Warren, MI, to review recent case studies that highlight unexpected presentations, treatment responses, and immune system interplay in dermatology. The first case focuses on a 34-year-old patient with severe, recalcitrant Hailey-Hailey disease. After multiple failed therapies, including antibiotics, corticosteroids, apremilast, and low-dose naltrexone, she achieved near-complete clearance within 12 weeks on dupilumab. Drs Altman and Del Rosso share their thoughts on why a drug targeting type 2 inflammation might be effective in a condition traditionally considered structural, drawing parallels to reports in Darier disease. Next, the conversation shifts to an unusual immune response observed in a patient with well-controlled psoriasis on IL-17 inhibitors who developed widespread atopic dermatitis. Dr Altman describes this as a “cytokine shift,” where suppression of IL-17 may upregulate IL-4 pathways, mirroring the reverse effect sometimes seen with IL-4 inhibition. While uncommon, such effects are now recognized in prescribing information, and the patient improved after transitioning to a broader-acting JAK inhibitor (upadacitinib). In the final case, a patient with Crohn’s disease developed rapidly progressing alopecia areata while on infliximab. Switching to tofacitinib improved hair growth but worsened gastrointestinal symptoms. Following colectomy, both the Crohn’s disease and alopecia resolved, highlighting the role of systemic inflammation in driving skin disease. Tune in to the full episode to hear more about these unique cases, the underlying immunologic mechanisms, and how lessons from complex cases can inform everyday dermatologic practice.

• A Youthful Approach to Maintaining Youthful & Healthy Skin: Here is How!

  In this episode of Derms and Conditions, host James Q. Del Rosso, DO, speaks with Heather Woolery-Lloyd, MD, dermatologist and director of the Skin of Color division at the University of Miami, about the shifting dynamics of skin care among younger generations and how dermatologists can meet this growing demand for evidence-based “prejuvenation” strategies. The discussion begins with reflections on how skin care priorities have shifted from basic sun protection and moisturization to a more proactive, appearance-driven approach, especially among Gen Z. While this interest is largely aesthetic, Drs Del Rosso and Woolery-Lloyd point out that it also brings health benefits, offering dermatologists a unique opportunity to guide patients toward sound practices for photoprotection and skin longevity. They also explore the influence of social media on how young people consume skin care information. Dr Woolery-Lloyd shares findings from her research showing that most viral skin care content is not produced by medical professionals, increasing the risk of misinformation, but also noting that many young people are increasingly capable of distinguishing influencer marketing from expert guidance. They further discuss how younger patients are seeking neuromodulators and fillers as preventive strategies. Dr Del Rosso highlights the biological rationale behind these concerns, including early collagen loss and environmental skin damage. They conclude with a review of emerging ingredients like acetyl dipeptide-31 amide and bakuchiol, which offer dermal benefits with minimal irritation, potentially impacting how dermatologists counsel younger patients who are hesitant to use traditional retinoids. Tune in to the full episode to hear how dermatologists can thoughtfully engage with this prevention-minded population by acknowledging their concerns, correcting misinformation, and recommending science-backed products that promote both skin health and confidence.
