For Malignant Melanoma (MM), the Breslow thickness and the presence of ulceration are important elements for determining the staging and prognosis¹. Skin cancer screening and dermoscopic examination allowed an earlier recognition of cutaneous MM, causing especially an over‐detection of thin lesions, without a proportional decline in later‐stage disease². Furthermore, the incidence of thicker MMs does not seem to be decreasing^3;4.

Background: Line-field confocal optical coherence tomography is a novel technology able to reproduce a “virtual biopsy” of the skin. The aim of this review is to explore the application of line-field confocal optical coherence tomography (LC-OCT) in various skin diseases, covering skin cancers, inflammatory and infectious skin diseases, genetic diseases, cosmetic procedures, and less common disorders. Methods: Study selection was conducted based on LC-OCT and using pertinent MeSh terms, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines from inception to March 2024; to evaluate the quality and risk of bias of studies, Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) was used. Results: the search retrieved 154 papers according to the selection criteria; after removing publications by one or more of the exclusion criteria, a total of 96 studies were found to be suitable for the analysis. Conclusions: Increasing evidence supports the use of LC-OCT as an adjunctive diagnostic tool for the in vivo diagnosis of a variety of skin tumors. As this device can be considered a “bridge” between dermoscopy and histopathology, widening applications in numerous fields of clinical dermatology, including inflammatory skin disease treatment, presurgical mapping, cosmetic procedures, and monitoring of non-invasive therapies, have been explored.

Background: Dermatofibrosarcoma protuberans (DFSP) is a superficial soft tissue sarcoma, and surgical excision is the first-line treatment. The aim of this systematic review is to provide an update about the current indications and clinical results regarding the use of postoperative radiotherapy in DSFP, considering both adjuvant and salvage setting. Methods: We conducted a systematic literature review using the main scientific database, including Cochrane library, Scopus, and PubMed, for any relevant article about the topic, and we considered all available papers without any time restriction. Results: Twenty-two papers, published between 1989 and 2023, were retrieved and considered eligible for inclusion in this review. Regarding the fractionation schedules, most authors reported using standard fractionation (2 Gy/die) with a wide total dose ranging from 50 to 70 Gy. The local control after postoperative radiotherapy was excellent (75–100%), with a median follow-up time of 69 months. Conclusions: After the primary surgical management of DFSP, postoperative radiotherapy may either be considered as adjuvant treatment (presence of risk factors, i.e., close margins, recurrent tumours, aggressive histological subtypes) or as salvage treatment (positive margins) and should be assessed within the frame of multidisciplinary evaluation.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease that affects intertriginous skin areas, clinically characterized by recurrent inflamed nodules, abscesses, sinus tracts, and severe scars. Systemic treatments may provide temporary relief, while wide surgical excision offers prolonged disease‐free periods. We evaluated the most efficient wound closure methods following wide excision of HS lesions in terms of recurrence, functionality, and quality of life. A systematic literature search was conducted in PubMed, Embase, Cochrane, and ClinicalTrials.gov , adhering to the PRISMA 2020 criteria. We included original studies published until February 2024, focusing on wound closure methods post‐wide excision for HS. Data from 121 papers were analyzed using network and direct meta‐analysis methods to compare recurrence and postoperative complication rates. From 1181 articles, 121 were included in the meta‐analysis after removing duplicates and excluding publications that did not meet the inclusion criteria. Recurrence rates were associated with the type of reconstruction technique as follows: primary closure, 25% (95% confidence interval [CI], 20–30%); skin grafts, 18% (95% CI, 14–22%), and flaps, 12% (95% CI, 9–15%). Secondary intention healing showed a recurrence rate of 28% (95% CI, 23–33%). Flaps were associated with the lowest recurrence rates compared to other surgery techniques.
