Basal cell carcinoma (BCC) is the most common malignant tumor in white populations. Multiple studies demonstrated that the aberrant activation of Hedgehog signaling is a driver of BCC development, and its blockade represents a potential therapeutic target. In Italy, clinicians can prescribe Hedgehog inhibitors (HhIs) vismodegib and sonidegib.

Clear communication between dermatologists and histopathologists, along with the possibility of sharing clinical images, is critically important. This survey aims to depict the level of communication between dermatologists and histopathologists in clinical practice in Italy.
View Article and Find Full Text PDFTattooing is a widespread practice among the population, particularly among young people. With the increased popularity of tattoos, there have also been several reports of acute and chronic adverse events after tattooing. Malignant melanoma cases arising from tattoos have been increasingly described; however, there is no clear relationship between this practice and tumorigenesis.

Owing to the still-to-date limited knowledge of spHS genetics, we calculated polygenic scores (PGSs) to study the genetic underpinnings that contribute to spHS within European demographic. A total of 256 patients with spHS and 1686 healthy controls were analyzed across 6 European clinical centers.
View Article and Find Full Text PDFActinic keratosis (AK) is a widespread pre-cancerous skin condition that may evolve to squamous cell carcinoma, a non-melanoma skin cancer, which is able to become locally invasive and metastatic. Thus, it is important to treat AK. : We conducted a cost-effectiveness analysis for the field-directed therapeutic approaches: local application of drugs containing 5-fluorouracil, both alone at a 4% concentration and associated to 10% salicylic acid at a 0.

A part of them has only recently been identified, revealing novel causative genes and very rare phenotypes of these genetic skin disorders. At the same time, the molecular basis of previously published and unresolved cases has been revealed through the introduction of innovative genetic techniques.

BCC dermoscopic criteria have been updated and divided into vascular, pigment-related, and non-vascular/non-pigment-related. Our multicenter retrospective study tested a new dermoscopic pigment-related characteristic to detect pigmented BCC (pBCC) [brown homogeneous blotches (BHB)].

Despite its etiopathogenesis remains largely unknown, several trigger and predisposing factors have been reported. Pemphigus is caused by autoantibodies that target desmoglein 1 and desmoglein 3, impacting desmosome function.

It usually appears in the second and third decades, but a smaller proportion of patients develop late-onset HS. Geriatric HS, defined as the persistence or the development of HS after the age of 65 years, has been poorly explored.
View Article and Find Full Text PDFBackground: Recent studies are stressing the idea that the level of Hidradenitis Suppurativa (HS) severity does not always correspond to the same illness load. In fact, it was found that there was no significant association between Skindex-17 and clinical severity of HS, and that some items of the Skindex-17 might be more related to HS severity than others.
Objective: The aim of the current study was to explore the associations between different levels of clinical severity of HS (mild, moderate, severe) and the Skindex-17 single-item responses in a large sample of adults patients.
Autoimmune bullous diseases are a heterogeneous group of rare conditions clinically characterized by the presence of blisters and/or erosions on the skin and the mucous membranes. Practically, they can be divided into two large groups: the pemphigoid group and the pemphigus group, depending on the depth of the autoimmune process on the skin. A family history of autoimmune diseases can often be found, demonstrating that genetic predisposition is crucial for their development.

If diagnosed late and improperly treated, BCC and SCC can become locally advanced and metastasize. Malignant melanoma (MM) is less frequent but more lethal than NMSC.

Skin findings are often the initial presenting signs, and cutaneous sarcoidosis may appear with a wide variety of lesions; it is often considered an imitator of many other skin diseases. Clinical appearance and specific dermoscopic criteria, confirmed by a typical pathology, may guide to the correct diagnosis.
View Article and Find Full Text PDFNon-melanoma skin cancer (NMSC) is a tumor that arises from human keratinocytes, showing abnormal control of cell proliferation and aberrant stratification. Cutaneous basal cell carcinoma (cBCC) and cutaneous squamous cell carcinoma (cSCC) are the most common sub-types of NMSC. From a molecular point of view, we are still far from fully understanding the molecular mechanisms behind the onset and progression of NMSC and to unravel targetable vulnerabilities to leverage for their treatment, which is still essentially based on surgery.

Objectives: Here, we report a case study of melanoma occurring on a tattoo on the left arm and provide an overview of all cases reported so far.
Materials & Methods: A systematic literature search of publications was conducted from inception to September 2021 via Medline (PubMed), Scopus and Google Scholar, in order to identify all cases of primitive melanomas arising on tattoos.
Background: The impact of melanoma on quality of life (QoL) is not limited to the patient but may also affect caregivers.
Objectives: To investigate the impact of melanoma on caregivers' QoL.
Materials & Methods: Caregivers of melanoma patients were recruited at the melanoma unit of our hospital.

Background: Pemphigus vulgaris is an autoimmune intraepithelial bullous disease involving the skin and the mucous membranes. Imiquimod, a topical therapy for skin basal cell carcinoma, is an amine that induces the production of tumor necrosis factor alfa, interleukin-1 and other cytokines. Pemphigus induced by drugs has been frequently reported, mostly after systemic therapy.
