Background:  It has been shown repeatedly that mast cells can promote or prevent cancer development and growth. If development and/or progression of a solid cancer is substantially influenced by mast cell activity, the frequencies of occurrence of solid cancers in patients with primary mast cells disorders would be expected to differ from the corresponding prevalence data in the general population. In fact, a recent study demonstrated that patients with systemic mastocytosis (i.e., a rare neoplastic variant of the primary mast cell activation disease) have increased risk for solid cancers, in particular melanoma and non-melanoma skin cancers...

BACKGROUND: Hydrochlorothiazide, one of the most frequently used diuretic and antihypertensive drugs in the United States and Western Europe, is photosensitizing and has previously been linked to lip cancer. OBJECTIVE: To examine the association between hydrochlorothiazide use and the risk of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). METHODS: From the Danish Cancer Registry, we identified patients (cases) with NMSC during 2004-2012...

This study presents, attenuated total reflection Fourier transforms infrared spectroscopy of dried serum samples in an effort to assess biochemical changes induced by non-Hodgkin's lymphoma and subcutaneous melanoma. An EL4 mouse model of non-Hodgkin lymphoma and a B16 mouse model of subcutaneous melanoma are used to extract a snapshot of tumor-associated alteration in the serum. The study of both cancer-bearing mouse models in wild types and their corresponding control types, emphasizes the diagnostic potential of this approach as a screening technique for non-Hodgkin lymphoma and melanoma skin cancer...

Asthma is a serious global health issue and the most prevalent chronic disorder among Danish pregnant women. Exacerbations of asthma during pregnancy have been associated with increased risk of adverse pregnancy and perinatal outcomes, and by that making asthma a potential serious medical condition during pregnancy. Monitoring of asthma every four to six weeks is recommended during pregnancy, although evidence is lacking that following this recommendation will improve pregnancy outcome and, not least, be beneficial for all pregnant women with asthma...

Following the publication of the results of a Phase III trial, the administration of oral nicotinamide has been widely advocated as effective in non-melanoma skin cancer chemoprevention in high-risk individuals. However, I performed a Bayesian analysis of the reported findings and show there is insufficient evidence to demonstrate its efficacy, highlighting the significant probability that the positive conclusions drawn will not be reproducible. Given the potential widespread use of oral nicotinamide, future position statements regarding its efficacy are likely to require higher standards of evidence...

Cutaneous human papillomaviruses (HPVs) are considered as cofactors for non-melanoma skin cancer (NMSC) development, especially in association with UVB. Extensively studied transgenic mouse models failed to mimic all aspects of virus-host interactions starting from primary infection to the appearance of a tumor. Using the natural model Mastomys coucha, which reflects the human situation in many aspects, we provide the first evidence that only UVB and Mastomys natalensis papillomavirus (MnPV) infection strongly promote NMSC formation...

REVIEW
Sebastian O Wendel, Nicholas A Wallace
While the role of genus alpha human papillomaviruses in the tumorigenesis and tumor maintenance of anogenital and oropharyngeal cancers is well-established, the role of genus beta human papilloviruses (β-HPVs) in non-melanoma skin cancers (NMSCs) is less certain. Persistent β-HPV infections cause NMSCs in sun-exposed skin of people with a rare genetic disorder, epidermodysplasia verruciformis. However, β-HPV infections in people without epidermodysplasia verruciformis are typically transient. Further, β-HPV gene expression is not necessary for tumor maintenance in the general population as on average there is fewer than one copy of the β-HPV genome per cell in NMSC tumor biopsies...

The tretinoin peel, also known as retinoic acid peel, is a superficial peeling often performed in dermatological clinics in Brazil. The first study on this was published in 2001, by Cuce et al., as a treatment option for melasma. Since then, other studies have reported its applicability with reasonable methodology, although without a consistent scientific background and consensus. Topical tretinoin is used for the treatment of various dermatoses such as acne, melasma, scars, skin aging and non-melanoma skin cancer...

Among childhood cancer survivors (CCSs), non-melanoma skin cancer (NMSC) is the most common type of second malignancy. Morbidity related to the development of NMSC in this group of patients may be sometimes unpredictable and difficult to manage. We present the case of a 49-year-old female who was a CCS and developed giant superficial basal cell carcinomas (sBCCs) over the previously irradiated field of the scalp. BCC involved the atrophic skin overlying the catheter of the peritoneal cerebral shunt that was set there for the management of hydrocephalus...

Non-melanoma skin cancer (NMSC) is a common reason for outpatient primary care visits. Uninsured patients may be at a higher risk for NMSC due to lack of access to health care and a possible increased risk of sun exposure due to insecure housing. The true incidence of NMSC in this population is unknown. In order to determine the population's incidence of NMSC we performed a retrospective chart review on all patients (n = 656) seen at the Lubbock Impact Free Clinic from July 1, 2014 through July 30, 2015. This highlighted an increased incidence of NMSC in our uninsured population (1...

Melanoma incidence is increasing. We evaluated risk of melanoma death after diagnosis of non-melanoma skin cancer (NMSC). We followed 77,288 female American nurses from the Nurses' Health Study from 1986 to 2012. We used Cox proportional hazards models to determine the hazard ratio (HR) of lethal and non-lethal melanoma diagnosis and melanoma death, according to personal NMSC history. Among melanoma cases, we examined the HR of melanoma death and the odds ratio (OR) of melanoma with a Breslow thickness ≥ 0...

Scientific publications place much emphasis on postoperative outcomes such as recurrence, but little attention to patients' satisfaction. The purpose of this evaluation was to find out patients' reported outcomes after their initial consultation, treatment, and follow-up appointments for non-melanoma skin cancer of the head and neck. We used an adapted version of the European Organisation for Research and Treatment of Cancer (EORTC) validated questionnaire for patients' satisfaction to collect data prospectively from consenting patients between September and December 2015...

We report 85 lesions of non-melanoma skin cancer in 58 patients, representing 9% of the minor surgical workload of a single general practitioner. Cases were studied in order to describe pathology, management and outcomes. Eighteen percent of lesions were referred, mainly because of central facial site and larger size. Of the lesions treated in the surgery, all but four were treated surgically. Quantitative margins of lateral and deep excision were reported for 50% and 30% of specimens respectively. Lateral histological margins of clearance were narrower for head and neck lesions...

BACKGROUND: Cutaneous leishmaniasis is distributed worldwide, including Brazil. Its several clinical forms need to be distinguished from other dermatoses. Clinical similarities and lack of a gold standard diagnostic tool make leishmaniasis-like lesions a challenging diagnosis. OBJECTIVES.: To report the final diagnosis of patients primarily suspected of having American tegumentary leishmaniasis (ATL). METHODS.: A retrospective cross-sectional study was conducted on the basis of medical records of 437 patients with clinical suspicion of ATL, registered in electronic hospital system between 1980 and 2013...

Although rates of late-stage melanoma are rising in Hispanics, particularly those living in high ultraviolet light environments, little is known about the prevalence of sun protective behaviors in Hispanic children. We analyzed baseline data including frequency of sunburn, sun protective behaviors, level of U.S. acculturation, and skin phototype from a cross-sectional survey of 2003 Hispanic elementary school children in Los Angeles, California, who participated in a skin cancer prevention intervention. Although the Hispanic children reported frequently engaging in some sun protective behaviors, they also had a high rate of sunburn (59%) that exceeded previous national estimates for non-Hispanic white children (43%)...

Metastases are involved in most cancer deaths. Evidence has suggested that cancer cell detachment from primary tumors might occur largely via the mechanism of epithelial-mesenchymal transition (EMT) activated by epigenetic events, but data addressing other possible triggers of detachment, particularly genetic mutations, have been limited. Using the Profile study of cancer genomics at Dana-Farber Cancer Institute, we examined somatic mutations in the EMT genes CDH1 in 5,106 primary carcinomas and CTNNB1 in 7,578 primary carcinomas across 13 anatomic sites: urinary bladder, breast, colon/rectum, endometrium, esophagus, kidney, lung, ovary, pancreas, prostate, skin (non-melanoma), stomach, and thyroid...
