REFLECTANCE CONFOCAL MICROSCOPY OF DERMAL PAPILLAE IN HEALTHY SKIN: A HISTOPATHOLOGY CONTROLLED STUDY.

Introduction: Previous studies have investigated the density of dermal papillae (DP) in normal skin using reflectance confocal microscopy (RCM), a non-invasive imaging technique that allows a real time, high-resolution imaging of the skin, although no histological confirmation was provided. The aim of the present study was to compare the RCM evaluation of DP density in healthy skin with horizontal histopathological sections (HHS), a technique that provides a horizontal view of the skin.

Methods: Ten adult patients were selected, and a healthy skin area was marked for RCM examination and a subsequent 5-mm punch biopsy that was processed for HHS.

Line-Field Confocal Optical Coherence Tomography Imaging of Psoriasis With Histopathology Correlation.

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.

[Tirbanibulin in the treatment of actinic keratoses: description of a case with instrumental evaluation and long-term follow-up.].

A 72-year-old man presented with actinic keratosis (AK) of the scalp confirmed by line-field confocal optical coherence tomography (LC-OCT) a novel non-invasive skin imaging technique. Patient was treated with Tirbanibulin 1% ointment once a day for 5 consecutive days and, after 8 days from baseline, mild erythema and desquamation was observed on the treated area, associated with mild pruritus. At the same time-point, L'LC-OCT revealed the presence of intraepidermal "targeted-like" cells, corresponding to apoptotic keratinocytes.

Impact of Topical Fluocinonide on Oral Lichen Planus Evolution: Randomized Controlled Clinical Trial.

Objective: To examine the impact of fluocinonide 0.05% gel formulation for the topical treatment of oral lichen planus (OLP).

Methods: Through an RCT design, 47 patients with OLP were randomly allocated for topical OLP treatment with fluocinonide 0.

Line-Field Confocal Optical Coherence Tomography: A New Skin Imaging Technique Reproducing a "Virtual Biopsy" with Evolving Clinical Applications in Dermatology.

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.

Line-field confocal optical coherence tomography of eyelid margin growths: A case series.

Background: The clinical differential diagnosis of lesions arising on the eyelid margin may be challenging and an unneeded surgical approach may have serious functional and aesthetic consequences. Nonetheless, early recognition and treatment of malignant tumors of the eyelid margin is mandatory. Line-field confocal optical coherence tomography (LC-OCT) is a novel tool for the in vivo, real-time skin imaging.

Utility of line-field confocal optical coherence tomography in the pediatric population.

Background: In the last decades diagnosis of dermatological diseases has achieved a significant progress with the aid of imaging technologies. In pediatric population dermatologic procedural investigations require special considerations, skill sets, and knowledge. Avoiding unnecessary invasive procedures in children is highly recommended to reduce psychological disturbance and cosmetical scars.

Line-field confocal optical coherence tomography of lentigo maligna with horizontal and vertical histopathologic correlations.

Lentigo maligna (LM) is a subtype of in situ melanoma that classically presents in elderly patients as a slowly growing lesion on sun-exposed areas that may evolve to invasive melanoma. Line-field confocal optical coherence tomography (LC-OCT) is a new non-invasive technique for a real-time, vertical, and horizontal skin imaging with high resolution close to conventional histopathology. We present the LC-OCT features of an LM of the nose in a 49-year-old white man along with their horizontal and vertical histopathological correlations.

Line-field confocal optical coherence tomography of psoriasis, eczema and lichen planus: a case series with histopathological correlation.

Background: Line-field confocal optical coherence tomography (LC-OCT) is a novel, non-invasive technique that provides in vivo, high-resolution images in both vertical and horizontal sections.

Objectives: The aim of the study was to evaluate LC-OCT imaging in some inflammatory disorders and to correlate the resulting features with histopathology.

Methods: The retrospective study included patients with histopathological confirmed diagnosis of plaque psoriasis, atopic eczema and lichen planus, who were imaged with LC-OCT before the biopsy.

Home treatment of single cutaneous warts combining face-to-face and teledermatology consultation: A new perspective.

During the COVID-19 pandemic, teledermatology services were set up and enhanced to take care of those benign conditions like cutaneous warts (CWs) which, if undiagnosed or treated with delay, could have worsened, enlarged, and potentially spread to the community. The aim of this hybrid exploratory trial was to combine face-to-face clinical and dermoscopic evaluation with teledermatology follow-up in the management of CWs with a cryogenic pen based on nitrous oxide for home treatment. Twelve adult patients affected by CWs were enrolled.

Porokeratosis Ptychotropica: Dermoscopy, Reflectance Confocal Microscopy, and Histopathological Correlation.

Porokeratosis ptychotropica (PP) is a rare variant of porokeratosis characterized by pruritic, symmetrical, red-brown verrucous papules, and plaques most commonly localized within the gluteal fold. Herein, we report the clinical, dermoscopy, and reflectance confocal microscopy (RCM) aspects of a case of PP in a 63-year-old Caucasian woman along with histopathological correlation. Both dermoscopy and RCM were able to recognize the , the histopathological clue shared by all clinical variants of porokeratosis.
