Breast Cancer-Related Neoplastic Alopecia: A Case Report and Review of the Literature

Neoplastic alopecia (NA) is defined as an organized hair loss in single or multiple areas of the scalp caused by a primary tumor that has metastasized to the skin of the scalp. Due to its localization and clinical appearance, NA should be placed in differential diagnosis with alopecia areata or other entities. To date, pathognomonic dermoscopic criteria of NA have not yet been described: the absence of classical criteria of other scalp diseases in addition to a major neovascularization with on-focus arborizing vessels and erosions or ulcerations may help the clinician to suspect a diagnosis of secondary alopecia. Dermatologists should pay more attention to these rare forms of secondarism because in exceptional cases, a simple alopecia of the scalp can hide a new, relapsing or metastatic neoplasia

Pattern of response of unresectable and metastatic cutaneous squamous cell carcinoma to programmed death-1 inhibitors: A review of the literature

Cutaneous squamous cell carcinoma (cSCC) is the second most frequent nonmelanoma skin cancer (NMSC). The majority of in situ cSCC [cSCC (Tis)] can be cured surgically, while local advanced and metastatic ones require other treatments, but there are no therapies approved by U.S. Food and Drug Administration (FDA). Available treatments for these stages included radiotherapy, chemotherapy as cisplatin, but responses to these treatments are usually of short duration. Programmed death-1 (PD-1) inhibitors (pembrolizumab, nivolumab, and cemiplimab) are an innovative immunologic treatment that now has been shown to be useful for the treatment of advanced cSCC. Nowadays, data about the response rate with the use of PD-1 inhibitors in cSCC are still few and, especially, the duration of the response after the start of treatment is short. Moreover, the number of cases is too small to express the beneficial effects of these treatments, although most data reported in the literature show quite good response rates. This review focused on some of the studies and associated results through an interesting research on search engines of all the cases about these systemic drugs, analyzing effects and side effects, and the research has been conducted considering published cases since March 2016 to October 2019

Benign dermatoses of the male genital areas: A review of the literature

The male genitalia are a common site of dermatoses. Patients with penile diseases often delay or avoid medical care due to anxiety and embarrassment. In this narrative review, we describe some of the main benign dermatoses localized to male genital, focusing on their epidemiology, clinical and dermoscopic features, as well as available therapies

Drug induced longitudinal melanonychia and transverse muerhcke's lines.

We describe the case of a 60 years old woman, who came to our attention in November 2017. She was worried about a "dark line" which had recently developed on the second finger nail of the right hand. The patient had a medical history of infiltrating ductal carcinoma of the breast and she had received in the Spring of 2017 six courses of adjuvant chemotherapy with Docetaxel and Cyclophosphamide, later in October 2017 she had started a hormonal therapy with Letrozole.

Is There More Than One Road to Nevus-Associated Melanoma?

The association of melanoma with a preexisting nevus is still a debated subject. Histopathological data support an associated nevus in approximately 30% of all excised melanomas. The annual risk of an individual melanocytic nevus becoming malignant is extremely low and has been estimated to be approximately 0.0005% (or less than 1 in 200,000) before the age of 40 years, to 0.003% (1 in 33,000) in patients older than 60 years. Current understanding, based on the noticeable, small, truly congenital nevi and nevi acquired early in life, is that the first develops before puberty, presents with a dermoscopic globular pattern, and persists for the lifetime, becoming later a dermal nevus in the adult. In contrast, acquired melanocytic nevi develop mostly at puberty and usually undergo spontaneous involution after the fifth decade of life. The purpose of this review is to analyze the data of the literature and to propose, on the basis of epidemiological and clinical-dermoscopic characteristics, a new model of melanogenesis of nevus-associated melanoma
