Dermoscopy of Riehl's melanosis: a case report and a short review of the literature.

Riehl's melanosis (RM) is a pigmentary disorder, more common in individuals with dark skin phototypes, considered a form of pigmented contact dermatitis. In this paper we present a case of RM due to the rubber component of a work facial mask in which dermoscopy and patch test were the most important tools to help physicians in diagnosis. In addition, we reviewed the main dermoscopic clues that may be useful in differential diagnosis with other facial pigmentary disorders.

, an Emerging Drug-Resistant Dermatophyte: A Review of the Treatment Options.

Dermatophytosis is a prevalent superficial infection caused by filamentous fungi, primarily affecting the skin and/or its appendages. In recent years, there has been a notable increase in mycotic strains resistant to standard antifungal therapies, including , a dermatophyte of the complex. This review aims to provide a comprehensive overview of the treatment options for , elucidating their effectiveness in managing this challenging mycotic infection.

Treatment of locally advanced and metastatic basosquamous carcinoma, navigating among sonic hedgehog pathway inhibitors, immune checkpoint inhibitors, chemotherapy, and radiotherapy: A case series and literature review.

Locally advanced (laBSCs) and metastatic basosquamous carcinomas (mBSCs) represent a therapeutic challenge. By definition, these forms are not amenable to surgery or radiotherapy, but according to literature reports, sonic hedgehog pathway inhibitors (HHIs), anti-programmed death 1 receptor antibodies (anti-PD-1), and other treatment approaches involving chemotherapy, surgery, and radiotherapy have been used. This work features 5 real-life cases of advanced BSCs, treated at the Dermato-Oncology Unit of Trieste (Maggiore Hospital, University of Trieste).

Bullous pemphigoid triggered by dulaglutide: a case report and a review of the literature.

Bullous pemphigoid (BP) is an autoimmune disease with a chronic relapsing course, predominantly affecting elderly people. Drugs are one of the possible triggers. A class of antidiabetic drugs often associated with the development of BP are inhibitors of dipeptidyl peptidase 4 (DPP-4 inhibitors or gliptins), while less known is the association with glucagon-like-peptide-1 receptor agonists.

Pilomatrix Carcinoma: Report of Two Cases of the Head and Review of the Literature.

Background: Pilomatrix carcinoma (PC) is a rare skin tumor arising from hair follicle matrix cells. It is locally aggressive with a high rate of local recurrence after surgical excision. Few cases in the literature have been described and the management is not well defined.

Cutaneous vasculitis and vasculopathy in the era of COVID-19 pandemic.

Cutaneous vasculitides encompass a heterogeneous group of clinicopathological entities, which may occur as single-organ vasculitis of the skin or present as skin-limited variant of systemic vasculitis (i.e., skin-limited ANCA-associated vasculitis), and are triggered by various factors, including infections, drugs and vaccines.

Identifying Candidates for Immunotherapy among Patients with Non-Melanoma Skin Cancer: A Review of the Potential Predictors of Response.

Background: Non-melanoma skin cancer (NMSC) stands as an umbrella term for common cutaneous malignancies, including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), together with rarer cutaneous cancers, such as Merkel cell carcinoma (MCC) and other forms of adnexal cancers. The majority of NMSCs can be successfully treated with surgery or radiotherapy, but advanced and metastatic stages may require systemic approaches such as immunotherapy with immune checkpoint inhibitors (ICIs).

Summary: Since immunotherapy is not effective in all patients and can potentially lead to severe adverse effects, an important clinical question is how to properly identify those who could be suitable candidates for this therapeutic choice.

Locally advanced basal cell carcinoma: Real-life data with sonidegib.

In recent years, the category of hedgehog pathway inhibitor (HHI) has shown great results in patients with advanced basal cell carcinoma (aBCC), but few real-life data on efficacy and safety profile of sonidegib are available. We report our management of locally advanced BCCs (laBCCs) with sonidegib, also describing the favorable response of locally advanced basosquamous carcinomas (laBSCs) treated with this hedgehog signaling inhibitor. Sonidegib was generally well tolerated and it achieved high response rates, improving quality of life.
