Frozen section analysis has been used to increase the likelihood of complete excision of skin cancers and to minimize the risk for recurrence. The question of its accuracy has been addressed in many studies and this article adds data to the discussion. A retrospective study was performed of 60 consecutive cases in which frozen section diagnoses were compared with permanent sections. It was found that in 85% of the cases the frozen sections were accurate compared with the permanent sections, but in 13% of the total cases the margins were less than 1 mm. These results concur with the literature. The surgery and pathological examinations were performed in a community hospital in which there was no dermatopathologist. The authors review the limitations of frozen section diagnosis in skin cancers and show that frozen section may be necessary in select cases but not in most skin cancers.

Microneedles (MNs) serve as a revolutionary paradigm in transdermal drug delivery, heralding a viable resolution to the formidable barriers presented by the cutaneous interface. This review examines MNs as an advanced approach to enhancing dermatological pathology management. It explores the complex dermis structure and highlights the limitations of traditional transdermal methods, emphasizing MNs' advantage in bypassing the stratum corneum to deliver drugs directly to the subdermal matrix.

Introduction: A diagnosis of melanoma in situ presents negligible risk to a person's lifespan or physical well-being, but existing terminology makes it difficult for patients to distinguish these from higher risk invasive melanomas. This study aims to explore whether using an alternative label for melanoma in situ may influence patients' management choices and anxiety levels.
Methods And Analysis: This study is a between-subjects randomised online experiment, using hypothetical scenarios.

Background: Melanoma is a highly aggressive skin cancer, where early and accurate diagnosis is crucial to improve patient outcomes. Dermoscopy, a non-invasive imaging technique, aids in melanoma detection but can be limited by subjective interpretation. Recently, machine learning and deep learning techniques have shown promise in enhancing diagnostic precision by automating the analysis of dermoscopy images.

Background: Locally advanced periorbital cutaneous squamous cell carcinoma (cSCC) may require orbital exenteration, which is highly morbid. As immunotherapy develops, orbit preservation may become widespread, and data benchmarking survival with current standard-of-care surgery and radiotherapy are essential to the integration of this emerging method into modern treatment paradigms. This study aimed to determine the survival of patients after orbital exenteration for cSCC and investigate contributing factors.

Purpose: Acute radiation dermatitis (ARD) is a frequent side effect experienced by breast cancer patients undergoing radiotherapy. This study aimed to assess the efficacy and safety of a topical cream containing aminoacryl tRNA synthetase complex interacting 1 (AIMP1)-derived peptide (AdP) in mitigating radiation dermatitis (RD) in breast cancer patients undergoing radiotherapy.
Methods: An 8-week single-center, prospective pilot study was conducted to compare the clinical efficacy and safety of an AdP-containing cream with a control cream lacking AdP for the mitigation of RD.
