Dermatopathology has rapidly advanced due to the implementation of deep learning models and artificial intelligence (AI). From convolutional neural networks (CNNs) to transformer-based foundation models, these systems are now capable of accurate whole-slide analysis and multimodal integration. This review synthesizes the most recent advents of deep-learning architecture and synthesizes its evolution from first-generation CNNs to hybrid CNN-transformer systems to large-scale foundational models such as Paige's PanDerm AI and Virchow. Herein, we examine performance benchmarks from real-world deployments of major dermatopathology deep learning models (DermAI, PathAssist Derm), as well as emerging next-generation models still under research and development. We assess barriers to clinical workflow adoption such as dataset bias, AI interpretability, and government regulation. Further, we discuss potential future research directions and emphasize the need for diverse, prospectively curated datasets, explainability frameworks for trust in AI, and rigorous compliance to Good Machine-Learning-Practice (GMLP) to achieve safe and scalable deep learning dermatopathology models that can fully integrate into clinical workflows.

Radiation recall dermatitis is a known but rare adverse effect that is characterized by the development of dermatitis in the region of prior irradiated tissue triggered by exposure to a systemic agent. Capivasertib is a small-molecule inhibitor targeting the phosphatidylinositol 3-kinase/protein kinase B pathway recently approved in locally advanced and metastatic breast cancer; however, the safety of its use in the setting of palliative radiation is currently unclear. Here, we report a case of radiation recall dermatitis in a patient with metastatic breast cancer on capivasertib with history of radiation to the right lower extremity managed with corticosteroids, antibiotics, and switching to alpelisib.

Sarcoidosis is a multisystem disorder characterised by granulomatous inflammation affecting various organs. The skin is commonly involved and can serve as an initial indicator of disease. While the precise aetiology of sarcoidosis remains elusive, evidence suggests involvement of T-helper type (TH)-1 and TH-17 pathways. Psoriasis shares common inflammatory pathways with sarcoidosis, prompting the repurposing of biologic therapies approved for psoriasis for off-label treatment of cutaneous sarcoidosis. However, this approach has raised concerns due to the development of granulomatous eruptions in some patients. We present a case of a patient with psoriasis who was diagnosed with systemic sarcoidosis while on ustekinumab. We review previous cases of ustekinumab-associated sarcoidosis and discuss the challenges associated with utilising biologic agents originally intended for psoriasis treatment for sarcoidosis.

Correct coding is an important component of effective dermatology practice management. Over the past several years there have been updates to many commonly used codes within dermatology. This review highlights many of these updates, such as: the skin biopsy codes have been subdivided to reflect the different biopsy techniques. The definition of complex linear repairs has been updated and clarified. Outpatient and inpatient evaluation and management visits have new coding guidelines to determine level of care. Dermatopathology consultation codes have been updated and category III codes related to digital pathology have been created. Understanding the details and nuances of each of these categories of codes is vital to ensuring appropriate coding is performed.

The 2023 ruling by the Supreme Court of the United States (SCOTUS) on the use of race-based criteria in college admissions may have implications for the selection of individuals into the dermatology workforce. This article highlights the impact of these decisions at the undergraduate, medical school, and graduate medical education levels, as well as within the field of dermatology.

On January 1, 2024, the new add-on complexity code for evaluation and management (E/M) services, G2211, went into effect. Understanding appropriate use of this code and how it can and cannot be utilized is of importance for all physicians. This article discusses the nuances of this code and gives examples of how to effectively incorporate it into practice.

Dermatology referral utilization is increasing, with 15% of dermatology-related visits by primary care resulting in a dermatology referral. Given this, both strengthening an expanding a referral is a key component of a successful dermatology practice. In particular, effective communication is essential for efficient patient-oriented coordinated care. Written and/or verbal communication can help build a strong communication network and, in some instances, can be applied toward Merit-based Incentive Payment System (MIPS) reporting and billing for coding families that incorporate the coordination of care. Reaching out directly to referring clinics has also been shown to increase the quantity of referrals. This can include providing clinics with patient handouts on your clinic, education on what information is prioritized within the referral, and educating staff on how to complete their referrals effectively and efficiently. Social media can play an important role in referrals, especially for patients looking for cosmetic care. There are many different platforms, and these can serve as a marketing tool for physicians looking to bring in new patients.
