Background: Kaposi's sarcoma (KS) is an unusual, clinically polymorphic, vascular neoplasm with genetic, infectious, environmental and immunological pathogenesis. Reflectance confocal microscopy (RCM) made in vivo noninvasive imaging of the skin possible and has been used for the evaluation of several skin diseases offering important microscopic information.
Objective: The purpose of our study is to describe the RCM features of KS and correlate them with histopathology evaluating the effective prediction attitude and repeatability of RCM.
Methods: Twelve KS lesions underwent RCM followed by histological examination. Data obtained were statistically correlated.
Results: Analysis of the incidence of 11 selected microscopic criteria (by RCM and optical histology: inflammatory cells in the epidermis and in the dermis, single or in aggregates; spindle cells; stroma; anastomosing, newborn, increased number and dilated vessels; extravasated erythrocytes; deposits of hemosiderin) was performed disclosing a good correlation and high sensitivity of RCM.
Conclusion: In our study RCM seems to provide high accuracy to predict histological findings, demonstrating its possible role in the management of patients affected by KS.

Introduction: Liposomes are versatile delivery systems for encapsulating small interfering RNAs (siRNAs) because they enhance cellular uptake and gene silencing. This study compares the new liposome formula to commercial lipofectamine in delivering siRNAs targeting hepatic carcinoma genes, focusing on HNF4-α and PFKFB4.
Methods: Flow cytometry and confocal microscopy revealed efficient internalization of PE-Rhod- B labeled lipoplexes in HepG2 cells, while cytotoxicity assays demonstrated significant reductions in cell viability, particularly with siHNF4-α and siPFKFB4.
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.

Patients with progressing facial vitiligo who had been treated with upadacitinib, 308 nm excimer light and upadacitinib combined with 308 nm excimer light were selected for retrospective analysis and comparison of their efficacy and safety. Efficacy was evaluated using the Vitiligo Area Severity Index (VASI) and Dermatology Life Quality Index (DLQI) at baseline, after 8 weeks, and after 20 weeks. The progression of skin lesions was monitored through reflectance confocal microscopy (RCM), while adverse reactions were documented.

We present an interesting image of eruptive syringoma confirmed by histopathological assessment in a 37-year-old male who was consulted due to numerous brownish small macules and papules resembling maculopapular cutaneous mastocytosis (MPCM). We show difficulties in diagnosing ES, given its rare occurrence and resemblance to other dermatological disorders. Moreover, we discuss the role of dermoscopy and reflectance confocal microscopy in the differential diagnosis of syringoma.
