At present, choice of treatment for skin melanoma depends on empirical data on efficacy of medication. Individual treatment may be promoted if certain markers of sensitivity to chemotherapy are evaluated. We studied frequencies of expression of marker sensitivity to fluoropyrimidin [(FPd) (-1)], TS(-)0 and TS(-). TS(-/+) was reported in 36.1%. Sensitivity to platinum drugs [EPCC1(-) - 64.4%], taxotere drugs- [beta = tubulin(-) -72.7%], cyclooxygenase inhibitors [COX2(+)] - 8.9%, mutant tyrosokinase inhibitors [c = kit(+)] - 21.4%, PDGFR = beta(+) -35.5%. Marker expression in tumor tissue was heterogenous. Data on molecular-genetic characteristics of tumor may be used to individualize choice of drugs, dosage and to lower risk of toxicity. Use of cytostatics should be evaluated in clinic for their efficacy in skin melanoma with due consideration of prognostic markers.

Objectives: Cutaneous adnexal carcinomas (CACs) are rare skin cancers with no established treatment guidelines. Given the limited data, this study aims to explore the characteristics and outcomes of patients with CAC treated with radiation therapy (RT).
Methods: Patients diagnosed with CAC between 2000 and 2020 who received RT were included.

Background: Sunburn and intermittent sun exposure elevate melanoma skin cancer risk. Sun protection behaviours, including limiting sun exposure, seeking shade, wearing protective gear, and using sunscreen, help mitigate excessive sun exposure. Smartphone apps present a promising platform to enhance these behaviours.

From the Department of Plastic Surgery, Hull University Teaching Hospitals, East Riding of Yorkshire, United Kingdom.
Biodegradable temporizing matrix (BTM) is a synthetic biodegradable dermal matrix that helps develop a non-skin graft amenable wound bed (eg, over tendon or bone) into a graftable wound bed, by acting as an inert scaffold for angiogenesis and formation of granulation tissue. There is currently a paucity of evidence to encourage its use in scalp defects following skin malignancy excision. This retrospective analysis aimed to evaluate the utility of BTM in this patient subset.

Psoriasis and psoriatic arthritis are chronic inflammatory conditions that constitute a significant global health burden due to their prevalence and impact on quality of life. A deeper comprehension of psoriasis and psoriatic arthritis pathogenesis has recently led to the emergence of novel classes of biologics targeting the IL-23/Th17 pathway. The specific role of interleukin-12, -23, and -17 in cancer as either promoters or inhibitors is under investigation in various studies.

Background: In malignant melanoma, liver metastases significantly reduce survival, even despite highly effective new therapies. Given the increase in metabolic liver diseases such as metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated steatohepatitis (MASH), this study investigated the impact of liver sinusoidal endothelial cell (LSEC)-specific alterations in MASLD/MASH on hepatic melanoma metastasis.
Methods: Mice were fed a choline-deficient L-amino acid-defined (CDAA) diet for ten weeks to induce MASH-associated liver fibrosis, or a CDAA diet or a high fat diet (HFD) for shorter periods of time to induce early steatosis-associated alterations.
