cutaneous squamous cell

Philip R Cohen
Basal cell carcinoma is the most common skin cancer. Myoepithelial cells are specialized epithelial cells. Basal cell carcinoma with myoepithelial differentiation is a rare tumor. A 71-year-old man with a basal cell carcinoma with myoepithelial differentiation that presented as an asymptomatic red papule of two months duration on his forehead is described. Including the reported patient, this variant of basal cell carcinoma has been described in 16 patients: 11 men and five women. The patients ranged in age at diagnosis from 43 years to 83 years; the median age at diagnosis was 66 years...

Activated cancer-associated fibroblasts (CAFs) and fibroblasts that have undergone the epithelial-mesenchymal transition (EMT) in cancer stroma contribute to tumor progression and metastasis. However, no reports have investigated the CAF phenotype and its clinicopathological relevance in cutaneous malignant tumors, including basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma (MM). Here, we investigated the CAF phenotype in cutaneous malignant tumors based on their histology and immunohistochemical expression of CAF-related markers, including adipocyte enhancer-binding protein 1 (AEBP1), podoplanin, platelet derived growth factor receptor α (PDGFRα), PDGFRβ, fibroblast activating protein (FAP), CD10, S100A4, α-smooth muscle actin (α-SMA), and EMT-related markers (Zeb1, Slug and Twist)...

The aim of the present study was to identify the potential autophagy-related genes and to explore the underlying molecular mechanisms involved in cutaneous squamous cell carcinoma of head and neck (cSCCHN) by bioinformatics analysis. The Gene Expression Omnibus (GEO) series GSE86544 was downloaded from the GEO database. The primary data was generated from cSCCHN with clinical perineural invasion (PNI) and cSCCHN without PNI, and was further analyzed in order to identify differentially expressed genes (DEGs)...

BACKGROUND: Tumour stroma consists of a heterogeneous population of fibroblasts and related mesenchymal cells, collectively dubbed cancer-associated fibroblasts (CAFs). These CAFs are key players in cancer invasion of cutaneous squamous cell carcinoma (SCC). As we have shown earlier, papillary and reticular fibroblasts (Pfs and Rfs, respectively) have distinct effects on epidermal and dermal homeostasis, but their role in cancer invasion and epithelial-to-mesenchymal transition (EMT) remains to be determined...

Cutaneous Squamous Cell Carcinoma (cSCC) is the second most common type of non-melanoma skin cancer in white-skinned populations. cSCC is associated with sun exposure and aging, which is concomitant with an accumulation of senescent cells in the skin. The involvement of senescent cells in carcinogenesis has been highlighted in several cancer types and an interaction between cSCC cells and senescent cells is proposed, but still little explored. Tumor-associated effects are mostly attributed to the senescence-associated secretory phenotype (SASP)...

Metastases to the parotid gland are the commonest cause of parotid malignancies in many regions of the world including Australia. The most common etiology of these metastases is head and neck cutaneous squamous cell carcinoma (HNcSCC) followed by melanoma of the head and neck. This article focuses on the management of the aforementioned pathologies including Merkel cell carcinoma (MCC).

Malignant transformation is associated with aberrant N-glycosylation, but the role of protein N-glycosylation in cancer progression remains poorly defined. β4-integrin is a major carrier of N-glycans and is associated with poor prognosis, tumorigenesis, and metastasis. Here, N-glycosylation of β4-integrin contributes to the activation of signaling pathways that promote β4-dependent tumor development and progression. Increased expression of β1,6GlcNAc-branched N-glycans was found to be co-localized with β4-integrin in human cutaneous squamous cell carcinoma tissues, and that the β1,6GlcNAc residue was abundant on β4-integrin in transformed keratinocytes...

BACKGROUND: Narrowband-ultraviolet B (NB-UVB) is widely used for the treatment of several dermatological diseases. A cutaneous carcinogenic effect has been hypothesized, but not proved. METHODS: We retrospectively reviewed the data of patients treated with NB-UVB between January 1998 and December 2013 at the Dermatology Unit of our University Hospital, to evaluate the cutaneous carcinogenic risk of NB-UVB. RESULTS: 375 patients were included, each receiving a mean follow-up of 6...

BACKGROUND: In addition to the extent of atypical keratinocytes throughout the epidermis, actinic keratoses (AKs) are histologically characterized by downward directed basal layer expansion. It is not known if this growth pattern correlates with the risk of developing invasive squamous cell carcinoma (iSCC). OBJECTIVE: To characterize the prevalence of downward directed basal layer expansion of AKs adjacent to iSCC. METHODS: The epidermis overlying and adjacent to iSCCs was assessed histologically...

Radiation oncologists are increasingly tasked with the management of elderly patients with non-melanoma skin cancer, unsuitable for surgical intervention due to inoperable lesions and/or poor performance status. In this cohort, hypofractionated radiotherapy, delivered either daily, alternative daily or once weekly is highly effective. A systematic literature search was conducted of PUBMED, MEDLINE and EMBASE databases using the algorithm ('radiotherapy' OR 'radiation therapy' OR 'brachytherapy') AND ('hypofraction' OR 'hypofractionated' OR 'hypofractionation') AND ('skin neoplasms' OR 'carcinoma' OR 'malignancy') AND ('skin' OR 'epidermis' OR 'epidermal' OR 'cutaneous')...
