The most common tumor of the western world is comprised of forms of non-melanoma skin cancers, previously known as keratinocyte carcinomas (KCs) The purpose of this study was to determine de incidence of non-melanoma skin tumors and the relationship between histopathological risk factors in patients with skin cancers. The study was composed from 332 cases of skin malignancies for which clinical and histopathological aggressivity factors were statistically analyzed through comparison tests and also stored digitally. For basal cell carcinoma (BCC) statistical analysis indicated significant relationships between pT category and gender, tumor size, ulceration, depth of invasion and positive resection limits. For squamous cell carcinoma (SCC) statistical analysis indicated significant relationships between pT category and tumor size, depth of invasion and positive resection limits. Clinical and histological analysis of certain characteristics of the above-mentioned skin cancers is an essential step in documenting and improving both prognosis and therapy standards.

This case report describes the presence of an acquirednaevus of Ito on a 78-year-old Dutch male. Naevus of Ito is a blue-grey discolouration that most commonly presents on Asian individuals during childhood. It is exceedingly rare for this naevus to occur later in life in a non-Asian individual.

Significance: Melanoma's rising incidence demands automatable high-throughput approaches for early detection such as total body scanners, integrated with computer-aided diagnosis. High-quality input data is necessary to improve diagnostic accuracy and reliability.
Aim: This work aims to develop a high-resolution optical skin imaging module and the software for acquiring and processing raw image data into high-resolution dermoscopic images using a focus stacking approach.

Mast cell tumors (MCTs) are the most common skin neoplasms in dogs and exhibit highly variable biological behavior. Metastasis primarily affects the lymph nodes, though less frequently, MCTs can infiltrate the spleen, liver, peripheral blood, and bone marrow. Flow cytometry of fine needle aspirate samples represents a non-invasive diagnostic procedure that has shown promise for detecting and quantifying mast cells in primary tumors and lymph nodes.

Introduction: Skin cancers primarily affect people of White ethnicity and lighter skin tones, but people of other ethnicities may face diagnostic delays and experience higher mortality, reflecting existing inequities in healthcare. This is the first study showing incidence data from the National Disease Registration Service (NDRS) cancer registry in England for skin cancers stratified by the seven broad ethnic groups.
Methods: We used data from NDRS from 2013-20 to analyse melanoma, acral lentiginous melanoma (ALM), basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), cutaneous T-cell lymphoma (CTCL), and Kaposi sarcoma (KS).
