Background: Large recurrent phyllodes breast tumors are often malignant. Therefore, when taking the surgical decision, a simple mastectomy and immediate reconstruction must be considered. Case presentation: The patient, aged 40 years, with benign tumor in left breast, having recurrence 2 years after, 4–7 cm conglomerate masses, was subjected to skin-reducing mastectomy, silicone mammary implant...

Summary : Skin melanoma is one of the deadliest among human skin tumors, and surgery remains first main method in its combined treatment. Despite seemingly radical nature surgical interventions patients with primary melanoma, frequency locoregional recurrence metastasis high. The question impact treatment on evolution microenvironment unclear. Aim to investigate dynamics polarization tumor-asso...

In this study, the effects of combining ursolic acid + resveratrol, for possible combined inhibitory effects on skin tumor promotion, were evaluated. Ursolic acid, resveratrol, and the combination of ursolic acid + resveratrol were applied topically prior to 12-O-tetracanoylphorbol-13-acetate (TPA) treatment on mouse skin to examine their effect on TPA-induced signaling pathways, epidermal hype...

Although it is well known that the majority of human cancers occur as the result of exposure to environmental carcinogens, it is clear that not all individuals exposed to a specific environmental carcinogen have the same risk of developing cancer. Considerable evidence indicates that common allelic variants of low-penetrance, tumor susceptibility genes are responsible for this interindividual v...

background and purpose: skin cancer is one of the most common types of cancer. several studies suggest a high incidence of skin cancer in most countries. timp-2 is the tissue inhibitor of matrix metalloproteinase and exist in both cancer and normal cells. the aim of this study was to investigate the expression of timp-2 gene in patients with skin cancer and evaluating the association between th...

Epidermal Langerhans cells (LC) are an integral component of the skin immune system as they initiate immune responses to a variety of antigens, including tumor antigens. When skin is exposed to carcinogenic doses of ultraviolet-B irradiation, chemical carcinogens or tumor promoters there is a significant reduction of LC density. This causes the skin to be immunocompromised and provides an oppor...

Cancer-associated fibroblasts (CAFs) are a key component of the tumor microenvironment and play an important role in disease progression treatment outcome. Here we used single-cell transcriptomics, CNV analysis, situ stainings to elucidate yet unresolved intra-tumoral CAF heterogeneity melanoma, basal squamous cell carcinoma. We identified three major subtypes, with their presence being indicat...

Tissue-resident memory T (TRM) cells have emerged as key players and potential immunotherapeutic targets in antitumor immunity. However, the study of TRM within TME has been hampered by a lack adequate tumor models. Cell lines injected subcutaneously do not contain same biological cues tumors arising from dermis epidermis, while most other models known tumor-specific antigen to track immune res...

Retinoic acid, a potent inhibitor of mouse skin tumor promotion by 12-O-tetradecanoylphorbol-13-acetate, fails to inhibit tumor formation by the complete carcinogen, 7, 12-dimethylbenz[a]anthracene (DMBA). To obtain further clues about the nature of the mechanism of the carcinogenic process as well as the mechanism of the effect of retinoic acid on tumor promotion, the effect of retinoic acid a...
