BACKGROUND: Real-time review of frozen sections underpins the quality of Mohs surgery. There is an unmet need for low-cost techniques that can improve Mohs surgery by reliably corroborating cancerous regions of interest and surgical margin proximity. OBJECTIVE: To test that deep learning models can identify nonmelanoma skin cancer regions in Mohs frozen section specimens. METHODS: Deep learning models were developed on archival images of focused microscopic views (FMVs) containing regions of annotated, invasive nonmelanoma skin cancer between 2015 and 2018, then validated on prospectively collected images in a temporal cohort (2019-2021)...

Basosquamous carcinoma (BSC), an uncommon and aggressive nonmelanoma skin cancer exhibiting characteristics ranging from basal cell carcinoma (BCC) to squamous cell carcinoma (SCC), is a subject of controversy in terms of its classification, pathogenesis, histologic morphology, biologic behavior, prognosis, and management. This narrative review is based on an electronic search of English-language articles in PubMed that included the terms "basosquamous carcinoma" and/or "metatypical carcinoma of the skin" in their titles...

Healthcare access greatly impacts skin cancer diagnosis and mortality rates. Recognition of current disparities in Mohs micrographic surgery (MMS) access can assist future policy and clinical decisions to correct them. For the years 2014-2018, the CPT codes for MMS (17,311 and 17,313) were counted on a per county level across the United States per the Medicare Centers for Medicare & Medicaid Services (CMS) Medicare Prescriber Database. Any county with 0 MMS CPT codes recorded were classified as "without MMS cases...

BACKGROUND: Nasal reconstruction after conventional surgical excision (CSE) of nonmelanoma skin cancer (NMSC) can be challenging. After excision and before the pathologic report, a simple reconstruction is favored. Yet, little is known about patient satisfaction after primary closure and second intention healing. OBJECTIVE: Patient satisfaction after nasal defect reconstruction with primary closure or second intention healing, using the FACE-Q Skin Cancer. METHODS: All patients who underwent CSE of nasal NMSC with immediate primary closure or second intention healing between March 2018 and March 2020 at Máxima Medisch Centrum Veldhoven were identified and asked to complete the FACE-Q Skin Cancer...

PURPOSE OF REVIEW: Nonmelanoma skin cancers (NMSC) represent a heterogeneous group of diseases that encompasses among the principal histologies basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and Merkel cell carcinoma (MCC). Given the fact that high tumor mutational burden due to ultraviolet mutagenesis represents a common hallmark of NMSCs, immunotherapy has proved to be a promising therapeutic approach in recent years. The aim of this review is to shed light on immunotherapy applications in NMSCs in the curative setting...

INTRODUCTION: Mohs Micrographic Surgery (MMS) is a treatment option for high-risk facial nonmelanoma skin cancer with high cure rates. Especially on the nasal tip, the tissue sparing properties of MMS are appealing. The nasal tip is a common location of nonmelanoma skin cancer and can be a challenging anatomical structure for reconstructive surgery due to its prominent location in the face, the shortage of spare tissue, as well as the stiffness and composition of different skin types, cartilage and bone...

BACKGROUND: Dermoscopic and reflectance confocal microscopy (RCM) correlations between morphologic groups of melanoma have not yet been described. OBJECTIVE: Describe and compare dermoscopic and RCM features of cutaneous melanomas with histopathological confirmation. METHODS: Single center, retrospective analysis of consecutive melanomas evaluated with RCM (2015-2019). Lesions were clinically classified as typical, nevus-like, amelanotic/nonmelanoma skin cancer (NMSC)-like, seborrheic keratosis (SK)-like and lentigo/lentigo maligna (LM)-like...

INTRODUCTION: This article aims to describe malignancies in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), or non-radiographic axial spondyloarthritis (nr-axSpA) treated with upadacitinib (UPA) or active comparators. METHODS: This integrated safety analysis includes data from 11 phase 3 UPA trials across RA (6 trials), PsA (2 trials), AS (2 trials; one phase 2b/3), and nr-axSpA (1 trial). Treatment-emergent adverse events (TEAEs) were summarized for RA (pooled UPA 15 mg [UPA15], pooled UPA 30 mg [UPA30], adalimumab 40 mg [ADA], methotrexate monotherapy [MTX]), PsA (pooled UPA15, pooled UPA30, ADA), AS (pooled UPA15), and nr-axSpA (UPA15)...

Due to their professional activities, outdoor workers are exposed to an increased risk of developing occupational skin cancer caused by solar ultraviolet (UV) radiation as defined by occupational disease (OD) number 5103. Since the amendment to the Occupational Diseases Ordinance ("Berufskrankheitenverordnung", BKV) in 2015, squamous cell carcinomas or multiple actinic keratoses of the skin caused by natural UV radiation in outdoor workers in Germany can be recognized as occupational disease in the sense of OD number 5103...

IMPORTANCE: Type 2 diabetes and colorectal cancer (CRC) disproportionately burden indviduals of low socioeconomic status and African American race. Although diabetes is an emerging CRC risk factor, associations between diabetes and CRC in these populations are understudied. OBJECTIVE: To determine if diabetes is associated with CRC risk in a cohort representing understudied populations. DESIGN, SETTING, AND PARTICIPANTS: This cohort study uses data from the prospective Southern Community Cohort Study in the US, which recruited from 2002 to 2009 and completed 3 follow-up surveys by 2018...

Nonmelanoma skin cancers (NMSC) are the most common skin cancers, and about 5.4 million people are diagnosed each year in the United States. A newly developed T-lymphokine-activated killer cell-originated protein kinase (TOPK) inhibitor, HI-TOPK-032, is effective in suppressing colon cancer cell growth, inducing the apoptosis of colon cancer cells and ultraviolet (UV) light-induced squamous cell carcinoma (SCC). This study aimed to investigate the physicochemical properties, permeation behavior, and cytotoxicity potential of HI-TOPK-032 prior to the development of a suitable topical formulation for targeted skin drug delivery...

INTRODUCTION: The dipeptidyl peptidase-4 (DPP-4) enzyme significantly influences carcinogenic pathways in the skin.

RESEARCH DESIGN AND METHODS: Using the United Kingdom Clinical Practice Research Datalink, we assembled two new-user active comparator cohorts for each skin cancer outcome from 2007 to 2019...

BACKGROUND: In patients with rheumatoid arthritis (RA), persistent inflammation and increasing disease activity are associated with increased risk of adverse events (AEs). OBJECTIVES: To assess relationships between RA disease activity and AEs of interest in patients treated with tofacitinib or tumor necrosis factor inhibitors (TNFi). DESIGN: This was a post hoc analysis of a long-term, postauthorization safety endpoint trial of tofacitinib versus TNFi...

BACKGROUND: Rosacea is a chronic inflammatory skin condition that predominantly manifests as facial flushing, irritation, and acne. Rosacea and cancer are thought to be linked by the commonality of inflammatory and immune response dysfunction. Studies that have looked into this possible association have reported mixed results. OBJECTIVE: Given the conflicting literature on this topic, our study sought to evaluate the overall association between rosacea and several cancers commonly investigated in the literature...

OBJECTIVE: To determine whether patients with lymphedema of a lower extremity (LE) had a greater risk of skin cancer than those without lymphedema. PATIENTS AND METHODS: This retrospective cohort study included patients with LE lymphedema examined at Mayo Clinic in Rochester, MN, USA, from January 1, 2000, through December 31, 2020. All patients with the phrase "lower extremity lymphedema" and a diagnostic code for lymphedema present in their electronic health record, as well as their age-, race-, and sex-matched controls without lymphedema, were included in the study...

Cutaneous squamous cell carcinoma (CSCC) is one of the most common malignant tumors of the skin, occurring primarily in the elderly population. CSCC is the second most common nonmelanoma skin malignancy in humans. The development of cutaneous squamous cell carcinoma is closely linked to environmental factors. Microplastics, as a new pollutant, are currently being intensively studied for their potential health effects. However, the effect of microplastics on skin cancer is not yet known and is an important scientific question that needs to be addressed...

IMPORTANCE: Genitourinary syndrome of menopause can be treated with vaginal estrogen therapy. However, there are concerns about the safety of vaginal estrogen therapy in patients with breast cancer.
