Sporotrichosis is an implantation mycosis caused by Sporothrix species. The global burden of disease is largely unknown, as routine surveillance is not conducted in most countries. The increasing disease burden paired with emerging zoonotic transmission highlight the growing public health significance of sporotrichosis. In this article, we describe the epidemiology and outline an approach to the diagnosis and treatment of sporotrichosis.

In contrast to the mandatory residency programs required of board-certified dermatologists, some dermatology departments and private practice groups offer optional postgraduate training programs for advanced practice providers (APPs). In this cross-sectional study, we identified and evaluated 10 postgraduate dermatology training programs for APPs across the United States. With the growing number of APPs in the dermatology workforce, it is important for dermatologists to be aware of these programs and the differences between physician and APP training to provide safe and effective care in collaborative or supervisory roles. Standardizing, improving, and providing high-quality education and promoting lifelong learning in the field of dermatology should be celebrated, and dermatologists are the skin experts best equipped to lead dermatologic education forward.

The American Contact Dermatitis Society named toluene-2,5-diamine sulfate (PTDS) the 2025 Allergen of the Year. Toluene-2,5-diamine sulfate is widely used as an alternative to para-phenylenediamine (PPD) in hair dyes but is itself a potent and likely underreported contact allergen. Cross-reactivity with PPD is common. Allergic contact dermatitis to PTDS manifests similarly to PPD reactions and disproportionately affects hairdressers and individuals who frequently use hair dye. Clinical recommendations include patch testing for PTDS and PPD (with consideration of delayed readings), occupational prevention, and use of safer dye alternatives where appropriate.

Botulinum toxin (BTX) is an effective treatment for improving prosthetic discomfort and reducing limb pain in amputees, particularly those experiencing hyperhidrosis of the residual limb. We describe a technique for administering BTX injections by dividing the residual limb into targeted areas and delivering the treatment in stages. This approach demonstrated an excellent outcome in our patient, enhancing comfort and managing hyperhidrosis. Our case underscores the importance of personalized treatment plans that are tailored to each patient's needs while also addressing factors that may affect their access to effective therapies.

Emergency departments (EDs) and immediate care (IC) centers frequently lack timely access to board-certified dermatologists, contributing to delays, misdiagnoses, and unnecessary treatments. Multiple studies show dermatology consultation often changes diagnosis and management and improves short-term clinical outcomes. Implementing a dermatology urgent care/IC model (initially referral-based with defined staffing blocks and triage rules) could reduce ED visits, shorten wait times, improve access for vulnerable patients and pediatric populations, and prevent interruptions in specialty therapies such as oncology and transplant care.

Steatocystomas are benign, sebum-filled cysts of the sebaceous follicle that typically manifest as firm nontender lesions of variable size and location. Steatocystomas may manifest as an isolated lesion (steatocystoma simplex [SS]), grouped lesions (steatocystoma multiplex [SM]), or suppurative variants (steatocystoma multiplex suppurativa [SMS]). Although generally asymptomatic, they occasionally can manifest with pruritus or pain and develop secondary infection or scarring, with specific subtypes such as SM and SMS displaying unique clinical features and complications. This comprehensive literature review presents an up-to-date overview of the etiology, presentation, and diagnostic modalities for this uncommon entity. It also provides insight into the history, epidemiology, and available management options for steatocystomas.
