Dermoscopic, Histological, Confocal Microscopy Correlation of Atypical-Dysplastic Melanocytic Nevi.

Introduction: The term "atypical melanocytic nevus" (AMN) is used as a synonym for dysplastic nevus (DN) in clinical practice. Although the criteria for diagnosis of AMN/DN by the Agency for Research on Cancer helps to differentiate AMN/DN from common acquired nevi, they do not have high degrees of specificity, as they are similar to those used for the diagnosis of melanoma.

Objectives: In this retrospective study we evaluated the correlation and diagnostic concordance of dermoscopy, confocal microscopy, and histological examination in 50 AMN.

The combination of oral and topical photoprotection with a standardized Polypodium leucotomos extract is beneficial against actinic keratosis.

Introduction: This study describes a prospective, multicentre, randomized controlled, open-label study with three arms aimed at studying the differences between: [Cnt], self-administered sun protection; [T], topical treatment; and [TO], topical + oral treatment; for the management of Actinic Keratosis (AK) in a cohort of subjects of advanced age displaying severe actinic damage (SAD).

Methods: Treatments administered to groups [T] and [TO] had a common component, which is a botanical extract, Fernblock, with demonstrated photoprotective activity.

Results: In total, 131 subjects were distributed randomly in the three groups, and followed up clinically at three separate time points, beginning of the study (t = 0) and after 6 and 12 months.

Skin ageing: Clinical aspects and in vivo microscopic patterns observed with reflectance confocal microscopy and optical coherence tomography.

Few studies have combined high-resolution, non-invasive imaging, such as standardized clinical images, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT), for age-related skin change characterization according to age groups. This study aimed to correlate clinical manifestations of ageing with skin cytoarchitectural background observed with high-resolution, non-invasive imaging according to age-related skin pattern distribution. A set of 140 non-pathological facial skin images were retrospectively retrieved from a research database.

De Novo Skin Neoplasms in Liver-Transplanted Patients: Single-Center Prospective Evaluation of 105 Cases.

: Solid-organ transplant recipients (SOTRs) are notably considered at risk for developing cutaneous malignancies. However, most of the existing literature is focused on kidney transplant-related non-melanoma skin cancers (NMSCs). Conflicting data have been published so far on NMSC incidence among liver transplant recipients (LTRs), and whether LTRs really should be considered at lower risk remains controversial.

Dermoscopy, confocal microscopy and optical coherence tomography features of main inflammatory and autoimmune skin diseases: A systematic review.

Background/objectives: Non-invasive skin imaging features of main skin inflammatory and autoimmune diseases have been reported, although a comprehensive review of their correlation with histopathologic features is currently lacking. Therefore, the aim of this paper was to review the correlation of dermoscopic, reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) criteria of main inflammatory and autoimmune skin diseases with their corresponding histopathologic criteria correlation.

Methods: Studies on human subjects affected by main inflammatory and autoimmune diseases, defining the correlation of dermoscopic, RCM or OCT with histopathologic criteria, were included in the review.

A plea for standardization of confocal microscopy and optical coherence tomography parameters to evaluate physiological and para-physiological skin conditions in cosmetic science.

Non-invasive reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) have been extended to the dermo-cosmetic field, for skin pathophysiology understanding and therapeutics monitoring. However, standardized methodology and parameters to interpret structures and changes in these settings are still lacking. Present study aimed to propose a validated standard methodology and a list of defined parameters for objective non-pathological skin assessments in the cosmetically sensitive cheekbone area of the face.

A solitary pink lesion: dermoscopy and RCM features of lichen planus.

We present an unusual onset of cutaneous lichen planus (LP) in a middle-aged patient. The initial presentation as solitary, indolent pink lesion required further investigations to rule out malignancy, especially amelanotic melanoma. Dermoscopy and reflectance confocal microscopy findings were found to be helpful in our case in addressing the correct diagnosis.

Pseudoepitheliomatous changes in a case of vegetating Darier–White disease: a unique histopathological finding.

Darier–White disease (DWD) is a rare autosomal dominant genodermatosis, characterized by constant and typical histopathological findings, such as hyperkeratosis, dyskeratosis with corps ronds and grains and papillary microvilli formation with suprabasal clefting. Despite its nearly constant histopathological presentation, unusual clinical variants are reported, such as the vegetating and cornifying ones. These variants share the same histopathological features of the classic type, except for the striking hyperkeratosis and acanthosis.
