Abstract
Line-field confocal optical coherence tomography (LC-OCT) is a novel imaging technique for in vivo examination of the skin that has recently been introduced in the dermatologic armamentarium of non-invasive diagnostic tools. Its usefulness in the diagnosis and treatment monitoring of some neoplastic, inflammatory, and infectious skin conditions has been demonstrated. The aim of this study was to evaluate the LC-OCT features of psoriasis in a large number of psoriatic plaques along with their histopathologic correlation. In this retrospective study, the LC-OCT and the corresponding histopathologic images of 100 psoriatic plaques of the trunk, upper and lower arms from 60 patients that underwent both procedures were evaluated and correlated. The following microscopic findings, typical of plaque psoriasis, were observed at both LC-OCT and histopathology: hyperkeratosis, parakeratosis, acanthosis, papillomatosis and vascular changes, Munro microabscesses, and pustules of Kogoj. The LC-OCT findings perfectly matched with histopathology. Our study confirms the usefulness of this new imaging technique in the non-invasive visualization of the common diagnostic clues of psoriasis.

Abstract
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.

Line-Field Optical Coherence Tomography: Usefulness in the Non-Invasive Differential Diagnosis of Congenital Alopecia of Infancy. Dermatol Pract Concept 2024; 14:dpc.1403a142.

Abstract
INTRODUCTION Soon after birth, the clinical differential diagnosis between sebaceous of Jadassohn (NSJ), congenital triangular alopecia (CTA) and aplasia cutis congenita (ACC) may be challenging. A certain overlap of standard dermoscopic features can occur, especially in atypical cases, depending on scalp skin morphology and maturation age. The recently developed line-field confocal optical coherence tomography (LC-OCT) can provide morphological skin details with cellular resolution trough a rapid non-invasive examination. OBJECTIVES To assess the LC-OCT features of 6 cases of congenital alopecia of different aetiologies, with both typical and atypical clinical appearance. METHODS A non-invasive imaging examination combining standard dermoscopy, high-resolution videodermoscopy (HRVD) and LC-OCT was realized in 7 babies presenting for congenital alopecia with overlapping features, aged between 5 months and 5 years. RESULTS Based on the specific LC-OCT features, and supported by HRVD features, a diagnosis of NSJ, congenital triangular alopecia (CTA) and AC) were made in 4, 2 and 1 case, respectively. CONCLUSIONS The combined LC-OCT plus HRVD non-invasive imaging bring the advantage to have a real time diagnosis, to set the proper management and allows to avoid a skin biopsy in the perinatal age/first years of life at delicate skin site.
