Abstract
BACKGROUND In vivo reflectance confocal microscopy (RCM) enables the study of architectural and cytological aspects in horizontal sections, which closely correlate with histologic features. However, traditional histopathological vertical sections cannot totally reproduce the image of the in vivo RCM horizontal section. OBJECTIVE To evaluate the concordance between in vivo RCM and histopathologic transverse sections for melanocytic lesions, basal cell carcinoma and seborrheic keratoses. METHODS Prospectively collected benign melanocytic and non-melanocytic tumours diagnosed by dermoscopy were evaluated for common RCM features and compared to histopathology in horizontal sections with haematoxylin and eosin staining. RESULTS A total of 44 skin tumours including 19 melanocytic lesions (nine compound, five junctional and five intradermal nevi), 12 basal cell carcinomas and 13 seborrheic keratoses were collected in the Department of Dermatology of Hospital Clinic of Barcelona. The RCM features that had statistically significant agreement with the histopathological horizontal sections were the preserved and visible honeycomb pattern, well defined DEJ, small bright particles, dermal nests, tumour islands and dark silhouettes, clefting, collagen bundles, thickened collagen bundles and cytologic atypia. CONCLUSIONS Histopathology evaluation of horizontal sections of skin tumours can be correlated with main RCM findings. The results of this study have improved the understanding and interpretation of RCM features in relation to skin tumours, thus reinforcing the utility of RCM as a diagnostic tool.

Abstract
BACKGROUND Sclerosing nevus with pseudomelanomatous features (SNPFs) is a clinical and pathologic entity that mimics melanoma both clinically and histologically. The lesion is a melanocytic nevus, histologically characterized by fibrosis and a pseudomelanomatous proliferation. It is typically seen in young to middle-aged individuals, mainly on the back, where microtrauma or inflammatory changes are more frequent. Dermoscopic description of SNPF has been reported so far in one case series. OBJECTIVE The aim of our study was to describe the dermoscopic and confocal features of SNPF. METHODS Histopathologically confirmed cases of SNPF were retrospectively collected from three referral centres in Italy. Only lesions with available clinical, dermoscopic and histopathological data were included; confocal images were also retrieved, when available. Lesions were evaluated for the presence of 12 dermoscopic and five confocal criteria previously described. RESULTS The study population included 93 lesions in as many patients (71 men and 22 women; median age: 38 years). Dermoscopically, we found a predominance of dark colours, in particular brown and blue, which were found in all lesions and the vast majority of the lesions (86/93; 92.5%) displayed at least one structureless area. By the combination of colours and structures, we observed that the majority of the lesions (67/92; 72%) were characterized by more than one structure and more than one colour. Confocal evaluation was performed on a subset of 24/93 lesions showing a regular architecture pattern (19/24 cases, 79%), with a predominance of the ringed pattern. The presence of focal cytologic atypia at the dermal-epidermal junction was present in 12/24 cases (50%) with a prevalent dendritic-shaped cell proliferation. CONCLUSIONS The current study demonstrated that SNPF was frequently characterized, on dermoscopic examination, by more than one structure and more than one colour and on confocal microscopy by a regular ringed pattern with focal dendritic atypical cells.
