AI Article Synopsis

  • Cutaneous squamous cell carcinoma (SCC) is a prevalent type of skin cancer in the U.S., with a focus on its genetic factors.
  • This study is the largest meta-analysis of SCC, examining over 19,000 cases and nearly 700,000 controls across six international groups.
  • Researchers identified eight new genetic variants linked to SCC and confirmed previously known ones, highlighting the importance of genes involved in skin regulation, immune response, and skin cell differentiation in the disease's risk.

Article Abstract

Cutaneous squamous cell carcinoma (SCC) is one of the most common cancers in the United States. Previous genome-wide association studies (GWAS) have identified 14 single nucleotide polymorphisms (SNPs) associated with cutaneous SCC. Here, we report the largest cutaneous SCC meta-analysis to date, representing six international cohorts and totaling 19,149 SCC cases and 680,049 controls. We discover eight novel loci associated with SCC, confirm all previously associated loci, and perform fine mapping of causal variants. The novel SNPs occur within skin-specific regulatory elements and implicate loci involved in cancer development, immune regulation, and keratinocyte differentiation in SCC susceptibility.

Cutaneous squamomelanocytic tumor (SMT) is a very rare cutaneous malignancy, composed of a dual phenotypic population of both malignant melanocytes and keratinocytes, intimately intermingled together. Herein, we report a new case of a SMT occurring in an 82-year-old man, located on the scalp. Histopathology revealed a mixed population consisting of squamous cell carcinoma and melanoma within the same lesion, also confirmed using immunohistochemical staining for high molecular-weight cytokeratins (HMWCKs) and Melan-A.

Human papillomaviruses (HPV) from the genus beta have been implicated in the development of cutaneous squamous cell cancer in and organ transplant patients. In contrast to alpha-high-risk HPV, which cause ano-genital and oropharyngeal cancers, beta-HPV replication is not well understood. The beta-HPV49 transcriptome was analyzed by RNA sequencing using stable keratinocyte cell lines maintaining high levels of extrachromosomally replicating E8- genomes, which can be established due to a lack of the viral E8^E2 repressor protein.

Considering the increasing use of immune checkpoint inhibitors in cancer treatment, our aim is to report a rare cutaneous immune-related adverse event induced by PD-1 inhibitor pembrolizumab and provide a brief overview of pembrolizumab-induced subacute cutaneous lupus erythematosus (SCLE) cases in the literature. We report a 67-year-old woman with oropharyngeal squamous cell carcinoma who developed SCLE during treatment with pembrolizumab. After 18 weeks (sixth cycle) of pembrolizumab immunotherapy, a widespread pruritic erythematous rash evaluated as grade 3 immune-related adverse event appeared primarily on the patient's limbs.

Background: Reconstruction of head and neck defects following tumor excision is one of the most challenging surgeries due to multiple reasons, such as associated cosmetic and functional impairments. The three-dimensional aspect of the defect makes it more difficult. Although in modern settings, microvascular surgery is preferred in many conditions, it requires the presence of resources and expertise.
