Skin cancer

Chau Yee Ng, Hsi Yen, Hui-Yi Hsiao, Shih-Chi Su
Skin is the largest human organ, our protection against various environmental assaults and noxious agents. Accumulation of these stress events may lead to the formation of skin cancers, including both melanoma and non-melanoma skin cancers. Although modern targeted therapies have ameliorated the management of cutaneous malignancies, a safer, more affordable, and more effective strategy for chemoprevention and treatment is clearly needed for the improvement of skin cancer care. Phytochemicals are biologically active compounds derived from plants and herbal products...

Nanoformulations derived from fine porous ZnO quantum dot nanoparticles (QD NPs) can offer strong potential medical applications; especially in cancer therapy. ZnO QD NPs was synthesized by sol-gel hydrothermal process, fast cold quenching and further smart surface functionalization methods to obtain ultrasmall size (1-4 nm) NPs. ZnO nanopolymer, a wetting agent, PEG co-solvent and water/oil emulsion stabilizer were considered in our nanofluid formulation. The resulting nanofluid was characterized by SEM, FTIR, photoluminescence, band gap energy, zeta potential and UV-Vis spectroscopy...

The skin cancers of the head and neck district are localized mostly on the nose, which, by being in the center of the mid-face, has an important aesthetic role. Therefore, many reconstructive techniques have been studied; among them regional skin flaps appeared the most suitable since they guaranteed the oncological radicality as well as a good aesthetic outcome. In this paper, we present our experience with the use of the Zitelli bilobed flap, which is defined as a double transposition flap for the reconstruction of the nose defects...

Fusarium species have emerged as responsible for a broad spectrum of infections, including superficial, locally invasive and disseminated ones, especially in the hospital environment. Since there are few reports of invasive and disseminated fusariosis in children, the aim of this study was to report four cases of nosocomial infection caused by this microorganism in children with cancer hospitalized in a public children's hospital located in Brazil. Two of these patients were female and two were male. All patients presented febrile neutropenia, while three patients had acute lymphocytic leukemia and one patient had Wilms' tumor as underlying disease...

Persistent genus β-HPV (human papillomavirus) infection is a major co-factor for non-melanoma skin cancer in patients suffering from the inherited skin disease epidermodysplasia verruciformis (EV). Malignant EV lesions are particularly associated with HPV type 5 or 8. There is clinical and molecular evidence that HPV8 actively suppresses epithelial immunosurveillance by interfering with the recruitment of Langerhans cells, which may favor viral persistence. Mechanisms how persistent HPV8 infection promotes the carcinogenic process are, however, less well understood...

Lung cancer is the most frequently diagnosed non-skin cancer and has a high mortality rate. Skin metastases that manifest as visceral malignancies are rare. Cutaneous metastasis from lung cancer has been observed in only 0.22%-12% of cases and is rarely the first manifestation of lung cancer. The histopathological features of metastases are occasionally difficult to distinguish from those of primary cutaneous tumors, despite the rigorous application of useful techniques, particularly immunohistochemistry. We report 3 asymptomatic cases of men who presented with solitary periumbilical, sacral, and scalp metastasis as the first manifestation of an underlying malignant lung tumor...

Here we report the case of a 77-year-old woman with a huge cancer of the right breast for which size was measured on computed tomography in our hospital preoperatively and in other hospital 3 years earlier. During the 3-year untreated interval, the tumor grew from 4 cm to 13 cm in maximum diameter, and the tumor-volume doubling time (TVDT) was calculated as 209 days. The patient underwent mastectomy with axillary lymph node dissection, with the large skin defect covered by autologous skin graft. The pathological diagnosis was pure mucinous carcinoma (MC) of the breast with a low MIB-1 index, no vessel invasion, and no lymph node metastasis...

OBJECTIVE: To describe occurrences of mortality due to cervical cancer in Recife (PE), in northeastern Brazil. METHOD: This was a time-series ecological study using data from the Mortality Information System (SIM) regarding the total number of deaths due to cervical cancer (C53 ICD10) that occurred between 2000 and 2012. RESULTS: It was observed that the risk of death due to this form of cancer was higher among women over 60 years of age, those of mixed skin color (53...

Obesity is a leading risk factor for post-menopausal breast cancer, and this is concerning as 40% of cancer diagnoses in 2014 were associated with overweight/obesity. Despite this epidemiological link, the underlying mechanism responsible is unknown. We recently published that visceral adipose tissue (VAT) releases FGF2 and stimulates the transformation of skin epithelial cells. Furthermore, obesity is differentially associated with many epithelial cancers, and this mechanistic link could be translational. As FGF2 and FGFR1 are implicated in breast cancer progression, we hypothesize that VAT-derived FGF2 plays a translational role in promoting adiposity-associated mammary epithelial cell transformation...

Merkel cell carcinoma (MCC) is a rare but aggressive skin cancer with frequent metastasis and death. MCC has a mortality rate of 30%, making it more lethal than malignant melanoma, and incidence of MCC has increased almost fourfold over the past 20 years in the USA. MCC has long been considered to be an immunogenic cancer because it occurs more frequently in immunosuppressed patients from organ transplant and HIV infection than in those with immunocompetent. Chronic UV light exposure and clonal integration of Merkel cell polyomavirus (MCPyV) are two major causative factors of MCC...

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...

Background: The submental island flap (SIF) is a pedicled flap based upon the submental artery and vein. Its utility in reconstruction following ablative head and neck procedures has been applied to various subsites including skin, lip, buccal mucosa, retromolar trigone, parotidectomy defects, and tongue. We review our experience using the SIF for reconstruction following tumor ablation. Methods: This prospective case series with medical record review includes consecutive patients undergoing SIF reconstruction following ablative surgery for malignancy at a single tertiary care facility between November 2014 and November 2016...

Electrochemotherapy is an emerging local treatment for the management of superficial tumors and, among these, also chest wall recurrences from breast cancer. Generally, the treatment of this peculiar type of tumor requires the coverage of large skin areas. In these cases, electrochemotherapy treatment by means of standard small size needle electrodes (an array of 0.73 cm spaced needles, which covers an area of 1.5 cm2 ) is time-consuming and can allow an inhomogeneous coverage of the target area. We have previously designed grid devices suitable for treating an area ranging from 12 to 200 cm2 ...

Importance: Skin cancer is the most common type of cancer in the United States. Although invasive melanoma accounts for only 2% of all skin cancer cases, it is responsible for 80% of skin cancer deaths. Basal and squamous cell carcinoma, the 2 predominant types of nonmelanoma skin cancer, represent the vast majority of skin cancer cases. Objective: To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on behavioral counseling for the primary prevention of skin cancer and the 2009 recommendation on screening for skin cancer with skin self-examination...
