Premalignant and Malignant Mucosal lesions: Clinical and Pathological Findings Part II. Premalignant and malignant mucosal lesions.

J Am Acad Dermatol 2018 Nov 14. Epub 2018 Nov 14.

Department of Dermatology, Boston University School of Medicine, Boston, MA. Electronic address:

Part 2 of this 2-part continuing medical education series discusses the clinical and histopathologic features of common premalignant and malignant lesions of the oral cavity. It is imperative for dermatologists to be able to recognize suspicious lesions, determine biopsy need, counsel, and refer patients presenting with premalignant or malignant conditions appropriately. Given the higher rates of mortality and morbidity of oral mucosal malignancies due to late diagnosis, appropriate treatment with multidisciplinary care in a timely manner is essential to these neoplasms.

Cutaneous Mycobacterial Infections.

Clin Microbiol Rev 2018 Jan 14;32(1). Epub 2018 Nov 14.

Servicio de Dermatología y Departamento de Micología, Hospital General de México, Mexico City, Mexico.

SUMMARYHumans encounter mycobacterial species due to their ubiquity in different environmental niches. In many individuals, pathogenic mycobacterial species may breach our first-line barrier defenses of the innate immune system and modulate the activation of phagocytes to cause disease of the respiratory tract or the skin and soft tissues, sometimes resulting in disseminated infection. Cutaneous mycobacterial infections may cause a wide range of clinical manifestations, which are divided into four main disease categories: (i) cutaneous manifestations of infection, (ii) Buruli ulcer caused by and other related slowly growing mycobacteria, (iii) leprosy caused by and , and (iv) cutaneous infections caused by rapidly growing mycobacteria.

Human papillomavirus infection is not involved in esophageal verrucous carcinoma.

Hum Pathol 2018 Nov 10. Epub 2018 Nov 10.

Department of Medicine, Surgical Pathology Unit, University of Padua, Padua, Italy.

Verrucous carcinoma of the esophagus (VCE) is a rare variant of squamous cell cancer, with a puzzling clinical, etiological, and molecular profile. The etiological involvement of human papillomavirus (HPV) in the cancer's natural history is controversial. This study considers nine cases of VCE, focusing on patients' clinical history before surgery, histological phenotype, immunophenotype (EGFR, E-cadherin, cyclin D1, p16, and p53 expression), HPV infection, and TP53 gene mutational status (exons 5-8).

Background: Verrucous carcinoma (VC) accounts for 1-10% of cases of squamous cell carcinoma (SCC) in the oral cavity, and 75% of VC occur in the oral cavity. Only 3% of primary intraosseous squamous cell carcinomas (PIOSCC), which means SCC occurring primarily in the bone, are VC. Verrucous carcinoma arising from odontogenic cysts (OC) is very rare, with only seven cases reported to date. Read More

Unusual Clinical Presentations of Malignant Melanoma: A Review of Clinical and Histologic Features with Special Emphasis on Dermatoscopic Findings.

Am J Clin Dermatol 2018 Nov;19(Suppl 1):15-23

Department of Dermatology, Universidad del Desarrollo, Clínica Alemana, Manquehue Norte 1410, Vitacura, Santiago, Chile.

This review presents the main challenges encountered when diagnosing unusual variants of malignant melanoma with the aim of raising awareness to allow application of the most appropriate treatment strategies. Although these melanomas are often rare, their misdiagnosis potentially jeopardizes patients' health and survival, and has medicolegal implications. The clinical and histologic presentations of melanoma vary greatly, and assessment of uncommon melanomas can be difficult for practitioners because of their scarcity and resemblance to other dermatologic entities.

Sebaceous naevus (sebaceous hamartoma) is a congenital lesion mainly localized to the scalp, whose clinical and histologic diagnosis is generally easy. In the vast majority of cases, it is diagnosed at birth, but it can sometimes go unnoticed and give the impression to occur later. This lesion may be complicated by benign tumors or more rare malignancies. Read More

Purpose: CARD9 deficiency is an inborn error of immunity that predisposes otherwise healthy humans to mucocutaneous and invasive fungal infections, mostly caused by Candida, but also by dermatophytes, Aspergillus, and other fungi. Phaeohyphomycosis are an emerging group of fungal infections caused by dematiaceous fungi (phaeohyphomycetes) and are being increasingly identified in patients with CARD9 deficiency.

Proliferative verrucous leukoplakia (PVL) is a potentially premalignant lesion that undergoes malignant transformation in over 40% of cases. Its clinical homogeneity suggests that a single or a small number of molecular pathogenic pathways may exist. Using the Cochrane protocol for systematic reviews, we have looked at the reported evidence of the molecular aetiology and pathogenesis of PVL and compared it with that of conventional oral epithelial dysplasia (OED).

Aim of this review article is evaluate and summarize the state of the art of HPV-related uro-genital cancers, focusing on the potentially innovative methods for the diagnosis of infection that should be used to improve viral causative detection and prevent its diffusion through sexual intercourses.

Verrucous hemangioma and histopathological differential diagnosis with angiokeratoma circumscriptum neviforme.

An Bras Dermatol 2018 Sep-Oct;93(5):712-715

Dermatology Department and Public Health Dermatology Outpatient Clinic, Porto Alegre, Rio Grande do Sul State Health Department, Porto Alegre (RS), Brazil.

Verrucous hemangioma is a rare vascular skin disorder with an immune profile similar to vascular neoplasms, but with behavior and evolution of vascular malformations. Its main differential diagnosis is angiokeratoma circumscriptum neviforme, with an almost indistinguishable clinical presentation because both diseases appear as erythematous patches that evolve to violaceous plaques, becoming scaly and even verrucous, most commonly affecting the lower limbs. Histopathology is crucial for the correct diagnosis: while in angiokeratoma the vascular alterations are limited to the papillary dermis, verrucous hemangioma extends deep into the dermis, reaching the subcutaneous tissue.

The Role of Human Papillomaviruses and Polyomaviruses in BRAF-Inhibitor Induced Cutaneous Squamous Cell Carcinoma and Benign Squamoproliferative Lesions.

Centre for Cell Biology and Cutaneous Research, Blizard Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, United Kingdom.

Human papillomavirus (HPV) has long been proposed as a cofactor in the pathogenesis of cutaneous squamous cell carcinoma (cSCC). More recently, the striking clinico-pathological features of cSCCs that complicate treatment of metastatic melanoma with inhibitors targeting BRAF mutations (BRAFi) has prompted speculation concerning a pathogenic role for oncogenic viruses. Here, we investigate HPV and human polyomaviruses (HPyV) and correlate with clinical, histologic, and genetic features in BRAFi-associated cSCC. Read More
