Introduction: Keratoacanthoma (KA) and squamous cell carcinoma (SCC) are two cutaneous conditions with morphological resemblance, which can complicate the diagnosis in some cases. Using immunohistochemistry staining of biomarkers could be beneficial in resolving this obstacle.
Objectives: We investigated a variety of biomarkers assessed in different studies in order to find the most important and helpful biomarkers for differentiation between SCC and lesions capable of spontaneous regression.
Methods: MEDLINE via PubMed and Google Scholar database were used to identify relevant literature up to 15 June 2022. The aim of our analyses was to determine the capability of biomarkers to distinguish between SCC and lesions capable of spontaneous regression using calculated individual and pooled odds ratios (OR) and 95% confidence intervals (CI) and I tests.
Results: Six potential biomarkers were CD10 with pooled OR= 0.006 (95% CI: 0.001-0.057) and I=0%; COX-2 with pooled OR=0.089 (95% CI: 0.029-0.269) and I=17.1%; elastic fibers with pooled OR= 6.69 (95% CI: 2.928-15.281) and I=0%; IMP-3 with pooled OR=0.145 (95% CI: 0.021-1.001) and I=44.5%; P53 with pooled OR=0.371 (95% CI: 0.188-0.733) and I=55.9%; AT1R with OR=0.026 (95% CI: 0.006-0.107).
Conclusions: We suggest the utilization of the following IHC biomarkers for discrimination between lesions with spontaneous regression such as KA and SCC: CD10, COX-2, and elastic fibers.

Background: Dermatomyositis is a chronic inflammatory condition affecting muscles and skin, often associated with an increased risk of cancer. Specific autoantibodies, including anti-TIF1 (Transcription Intermediary Factor 1), have been linked to this risk. We present a case of dermatomyositis in a male patient positive for anti-TIF1 antibodies, subsequently diagnosed with squamous cell carcinoma of the tonsil, a novel association not previously documented.

The objective of this retrospective observational study was to estimate the prevalence of actinic keratosis (AK) in individuals aged ≥ 40 years in France, to describe the characteristics of affected patients, and to describe treatments. A representative panel of 20,000 households with ≥ 1 member aged ≥ 40 years were invited to participate. Participants who reported AK lesions diagnosed by a physician were eligible.

Background: This study aimed to explore the relationship of cervical tumor lesion location (CTLL) with bilateral parametrial involvement (PI) and pelvic lymph node metastasis (LNM).
Methods: The study retrospectively analyzed the clinicopathologic and imaging data of patients with cervical squamous cell carcinoma (SCC) retrieved from multiple centers. According to the CTLL, patients were allocated to three groups: a middle one third group, a unilaterally dominant group, and the entire-region group.
TP53 Wild-type, HPV-independent Anal Growth/(intra)Epithelial Lesion (ANGEL): a Potential Precursor of Anal Squamous Cell Carcinoma.

Human papillomavirus (HPV) underpins approximately 90% of squamous cell carcinomas (SCC) of the anus and perianal region. These tumors usually arise in association with precursor lesions such anal intraepithelial neoplasia/ high-grade squamous intraepithelial lesion (AIN 3/ HSIL), whereas a small subset of HPV-negative cancers may harbor mutations in TP53. Recently, vulvar lesions termed differentiated exophytic vulvar intraepithelial lesion/vulvar acanthosis with altered differentiated (DEVIL/VAAD) have been recognized as HPV-independent, TP53 wild-type precursors for vulvar carcinoma; however, analogous anal lesions have not been described.

Anal HPV infection can cause squamous intraepithelial lesions (SILs), which are precursors of anal squamous cell carcinoma (SCC). The early detection of HPV infections and improvement of effective screening programmes are, therefore, essential to prevent progression from pre-cancerous lesions to SCC, especially in people living with HIV (PLWH), who represent a population at higher risk of HPV infection and associated lesions. Among prevention strategies, HPV vaccination is relevant too, but its efficacy in persons already infected by HPV is still debated.
