BACKGROUND: Mohs micrographic surgery (MMS) is the gold standard for treatment of high-risk skin cancers. There has been an upward trend in the use of this procedure as demonstrated by data from Medicare and the National Ambulatory Medical Care Survey. OBJECTIVE: To assess interest in MMS among members of the general public as measured by number of online searches, and how that interest has changed over time. MATERIALS AND METHODS: Google Trends was used to plot interest in search terms including "Mohs surgery," "basal cell carcinoma," "squamous cell carcinoma," "melanoma," and "skin cancer" from January 1, 2004, to November 30, 2016...

Cancer is a major cause of illness in Australia and therefore ongoing monitoring of cancer in Australia is important. This study sources data from the Australian Institute of Health and Welfare (AIHW) and reports actual number of cases diagnosed and deaths, for all cancers combined and selected cancers, from 1982 to 2013 for incidence and from 1982 to 2014 for mortality, with projections to 2017 for both. It is estimated that 134 174 new cases of cancer (excluding basal and squamous cell carcinomas of the skin) will be diagnosed in 2017...

MDM2, an E3 ubiquitin ligase, is a potent inhibitor of the p53 tumor suppressor and is elevated in many human cancers that retain wild-type p53. MDM2 SNP309G is a functional polymorphism that results in elevated levels of MDM2 (due to enhanced SP1 binding to the MDM2 promoter) thus decreasing p53 activity. Mdm2(SNP309G/G) mice are more prone to spontaneous tumor formation than Mdm2(SNP309T/T) mice, providing direct evidence for the impact of this SNP in tumor development. We asked whether environmental factors impact SNP309G function and show that SNP309G cooperates with ionizing radiation to exacerbate tumor development...

An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation...

BACKGROUND: Skin cancer patients are primarily at increased risk of developing subsequent skin cancers of the same type. Shared risk factors might also increase the occurrence of a different type of subsequent skin cancer. OBJECTIVE: To investigate risks of different skin tumor combinations after a first melanoma, squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). METHODS: All melanoma and SCC patients included in the national Netherlands Cancer Registry (NCR) and all BCC patients included in the regional Eindhoven Cancer Registry (ECR) between 1989 and 2009 were followed until diagnosis of a subsequent different skin cancer (melanoma, SCC or BCC), date of death or end of study...

Basal cell carcinoma (BCC) is the most common type of skin cancer, with rising incidence rates primarily attributed to an aging population and ultraviolet radiation exposure. While the majority of BCCs are localized and respond to standard therapies, a very small minority of these tumors become locally destructive or metastasize. These advanced BCCs may not be amenable to localized treatment with surgery and/or radiation therapy. Most BCCs result from mutations in key receptors in the Hedgehog (HH) signaling pathway...

BACKGROUND: Basal cell carcinoma (BCC) is the most common type of skin cancer with growing incidence rates. Photodynamic therapy (PDT) is a frequently used treatment, especially for superficial BCC (sBCC). Two topical photosensitizing agents are currently used to treat sBCC: 5-aminolevulinic acid (ALA) and its methyl-ester (MAL). Previous research showed a high efficacy of ALA-PDT using a 2-fold fractionated illumination scheme in which two light fractions of 20 and 80 J/cm2 are delivered, four and six hours after ALA application...

Inflammation is an important component of numerous cancers and chronic diseases and many inflammatory mediators have been shown to have potential prognostic roles. Tumor-infiltrating mast cells can promote tumor growth and angiogenesis, but the mechanism of mast cell activation is unclear. Early studies have shown that immunoglobulin free light chains (FLC) can trigger mast cell activation in an antigen-specific manner. Increased expression of FLC is observed within the stroma of many human cancers including those of breast, colon, lung, pancreas, kidney, and skin...

Importance: Protective effects of UV-B radiation against nonmelanoma skin cancer (NMSC) are exerted via signaling mechanisms involving the vitamin D receptor (VDR). Recent studies have examined single-nucleotide polymorphisms (SNPs) in the VDR, resulting in contradictory findings as to whether these polymorphisms increase a person's risk for NMSC. Objective: To examine whether the polymorphisms in the VDR gene are associated with the development of NMSC and the demographic characteristics of the participants...

Basal cell carcinoma (BCC) is the most common periocular skin cancer and can lead to significant morbidity. We assess the effectiveness of vismodegib, a first-in-class Hedgehog signaling pathway inhibitor, in the management of periocular and orbital BCCs based on clinical response, tolerability, and orbital content preservation. All patients with periocular or orbital BCCs who met criteria for vismodegib treatment were recruited prospectively between May 2012 and 2014 from 2 hospitals. Patients received oral vismodegib (150 mg daily) until disease progression, unacceptable toxicity, or withdrawal...

Basal cell carcinoma (BCC) is the most common skin cancer, mostly affecting areas of the skin exposed to UV radiation. Though metastasis is rare, the tumour may be locally invasive with a high recurrence rate. Pathophysiology involves neoplastic transformation of the pluripotent cells of the epidermis and follicular epithelium. 'Field fire BCC' is an uncommon type of BCC, showing concomitant crusting, ulceration and scarring which spreads peripherally with a central area of regression.

Nonmelanoma skin cancer is the most common cancer in humans, comprising mainly basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). BCC proliferation is highly dependent on the Hedgehog signaling pathway. We aimed to investigate a panel of anticancer drugs with known activity against skin cancer for their therapeutic potential in localized, enhanced topical treatment of SCC and BCC. Cytotoxicity profiles for vismodegib, 5-fluorouracil (5-FU), methotrexate (MTX), cisplatin, bleomycin, and vorinostat were established in terms of half maximal inhibitory concentration values in a panel of immortalized keratinocytes (HaCaT), BCC (UWBCC1 and BCC77015), and SCC (A431 and SCC25) cell lines...
