OBJECTIVE: The purpose of this meta-analysis was to evaluate the association between cyclooxygenase-2 (Cox-2) expression and skin cancer. MATERIALS AND METHODS: We searched the databases of PubMed, CNKI, and WANFANG to find the case-control studies associated with Cox-2 expression and skin cancer. The association between Cox-2 expression and skin cancer was demonstrated by odds ratio (OR) and its 95% confidence interval (95% CI). The publication bias was evaluated by funnel plot and Egger's line regression test...

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. Conventional diagnosis of BCC requires invasive biopsies. Recently, a high-definition optical coherence tomography (HD-OCT) technique has been developed, which provides a non-invasive in vivo imaging method of skin. Good agreements of BCC features between HD-OCT images and histopathological architecture have been found. Therefore it is possible to automatically detect BCC using HD-OCT. This paper presents a novel BCC detection method that consists of four steps: graph based skin surface segmentation, surface flattening, deep feature extraction and the BCC classification...

The authors address the entity of cutaneous lymphadenoma. Although considered benign, cutaneous lymphadenoma can be easily misdiagnosed as basal cell carcinoma because of its close clinical and histological resemblance. This entity is rare and controversial both in terms of its histogenesis and the various diagnostic terms assigned to it throughout the literature. While rare, cutaneous lymphadenoma should be considered in the differential of any facial nodule or papule in addition to the more common basal cell carcinoma, nevi, cysts, and appendiceal tumors...

BACKGROUND: The best way to approach surgically removed basal cell carcinoma with positive histopathological margins is a controversial issue. Some authors believe that the more appropriate treatment is an immediate reoperation while others prefer a periodic follow up. The rates of recurrence are variable in literature, between 10% and 67%. OBJECTIVE: To define the recurrence rate of basal cell carcinoma with positive margins after surgery. Secondarily, identify morphological aspects that can suggest a more frequent tumoral recurrence...

BACKGROUND: Basal cell carcinoma is the malignant tumor most often diagnosed in the National Campaign for Skin Cancer Prevention (NCSCP). Little is known about the profile of these lesions compared to the profile of lesions diagnosed by conventional routes of public dermatological care. OBJECTIVE: To identify if basal cell carcinomas identified in prevention campaigns and referred to surgery are smaller than those routinely removed in a same medical institution...

Cancer patients may be at decreased risk of Alzheimer's disease. This hypothesis is best developed for non-melanoma skin cancer (NMSC), but supportive epidemiological data are sparse. We therefore conducted a nationwide cohort study of the association between NMSC and Alzheimer's disease (main outcome) and all-cause dementia. Using Danish medical databases, we identified adults diagnosed with NMSC between 1 January 1980 and 30 November 2013 (n = 216,221) and a comparison cohort of five individuals matched to each NMSC patient by sex and birth year (n = 1,081,097)...

James Q Del Rosso
Ingenol mebutate is available as a topical gel formulation approved for the treatment of actinic keratosis. Two different concentrations are available for treatment of actinic keratoses at specific anatomic sites with the advantages of short durations of therapy and limited "down time" related to visible inflammation as compared to other topical agents. Due to the various modes of action of ingenol mebutate, it has also been used for treatment of disease states other than actinic keratosis. This manuscript discusses the suggested modes of action of ingenol mebutate and reviews publications on the use of ingenol mebutate gel for cutaneous disorders other than actinic keratosis, including squamous cell carcinoma in-situ, basal cell carcinoma, actinic cheilitis, anogenital warts, and others...

Secondary cutaneous amyloidosis refers to clinically unapparent amyloid deposits within the skin in association with a pre-existing skin condition or skin tumors, such as basal cell carcinoma, porokeratosis, solar elastosis, Bowen's disease, and mycosis fungoides. A 70-year-old woman presented with a 6-month history of asymptomatic multiple yellowish plaques on both legs. She had been diagnosed with mycosis fungoides 7 years ago and was treated with psoralen and ultraviolet A radiation (PUVA) therapy, narrow-band ultraviolet B (UVB) therapy, and acitretin for 5 years...

A 63-year-old woman presented with a large, ulcerokeratotic mass in her right lower eyelid that had grown over the last 2 months in a burn scar. She had experienced a thermal burn involving both inferior periorbital areas 35 years ago and received medical treatment. The lesion was excised with wide margins. The histologic diagnosis was squamous cell carcinoma. No recurrence was observed during a 22-month follow up. In the previous literature, a total of 10 cases of eyelid burn scar neoplasm, of which 9 were basal cell carcinoma, have been reported...

REVIEW
J A C Verkouteren, K H R Ramdas, M Wakkee, T Nijsten
Basal cell carcinoma (BCC) is the most common cancer in white-skinned individuals with increasing incidence rates worldwide. Patients with BCC place a large burden on healthcare systems, because of the high incidence and the increased risk of synchronous and metachronous BCCs and other ultraviolet radiation (UVR) related skin cancers (i.e. field cancerization). As a result, the disability-adjusted life years and healthcare costs have risen significantly in recent decades. BCC is a complex disease, in which the interplay between UVR, phenotype (UVR-sensitive) and genotype (somatic mutations and germline mutations/polymorphisms) fulfils a key role in the aetiopathogenesis...

Basal cell carcinoma is the most frequent cutaneous neoplasm, with slowly progressive nature and locally invasive behavior. Despite the low metastatic potential, local tissue destruction and disfigurement caused by the tumor can be large if not eradicated in time by early diagnosis and treatment. Both genetic predisposition and exposure to environmental risks are involved in the pathogenesis of the malignant transformation in BCC. The total number of nonmelanocytic skin cancers is a risk factor for recurrence of previous tumor, on the one hand, as well as for the formation of new ones, on the other...

BACKGROUND: Skin cancer is one of the most common cancers in the UK. Patients with suspicious skin lesions are assessed clinically with/without dermoscopy, and lesions still considered suspicious are then surgically removed or have the diagnosis confirmed by a punch biopsy. AIM: To evaluate the diagnostic accuracy of the in vivo VivaScope(©) reflective confocal microscopy (RCM) system, a noninvasive technology designed to provide a more accurate presurgical diagnosis, leading to fewer biopsies of benign lesions, or to provide greater accuracy for lesion margins...

There is uncertainty about the risk of developing non-melanoma skin cancer (NMSC), including basal cell carcinoma and squamous cell carcinoma (SCC), in patients with atopic dermatitis (AD) treated with oral immunosuppressive drugs. A total of 557 patients with AD treated with these drugs in the University Medical Center Utrecht and Groningen, the Netherlands, were analysed. NMSC after oral immunosuppressive treatment was reported in 18 patients (3.2%). The standardized incidence ratio for developing SCC was 13...

Li-Fraumeni syndrome (LFS) is a rare autosomal dominant disorder caused by a mutation in the p53 gene. Melanoma is considered to be a rare, controversial component of LFS. The aim of this study is to describe the utility of systematic screening for melanoma in patients with LFS and atypical mole syndrome. Two 28-year-old identical twin sisters with LFS and atypical moles were monitored by physical examination, total-body digital photography and dermoscopy be-tween 2006 and 2014. A total of 117, predominantly dark-brown, reticular naevi were identified on case 1 and 105 on case 2...

Approximately, 140 million people worldwide live permanently at high altitudes (HAs) and approximately another 40 million people travel to HA area (HAA) every year for reasons of occupation, sports or recreation. In India, whole of Ladakh region, part of Northwest Kashmir, Northern part of Sikkim and Tenga valley of Arunachal are considered inhabited areas of HAA. The low quantity of oxygen, high exposure of ultraviolet (UV) light, very low humidity, extreme subzero temperature in winter, high wind velocity, make this region difficult for lowlanders as well as for tourists...

BACKGROUND: We previously characterized in salivary adenoid cystic carcinoma (ACC) a novel population of cancer stem cells (CSCs) marked by coexpression of 2 stemness genes, sex-determining region Y (SRY)-related HMG box-containing factor 10 (SOX10) and CD133. We also reported that in ACC and basal-like breast carcinoma (BBC), a triple-negative breast cancer subtype, expression of SOX10 similarly demarcates a highly conserved gene signature enriched with neural stem cell genes. On the basis of these findings, we hypothesized that BBC might be likewise driven by SOX10-positive (SOX10(+))/CD133(+) cells with neural stem cell properties...

GATA3, as a transcription factor, is associated with estrogen receptor (ER) expression and necessary for luminal cell differentiation in mammary glands. Association of GATA3 expression with clinicopathological parameters, molecular subtypes of tumors, disease free survival (DFS) and overall survival (OS) for breast carcinoma patients were evaluated in this study. We immunohistochemically stained GATA3, CK5/6, EGFR, CK14 and vimentin on tissue microarray blocks of 457 invasive breast carcinomas. Tumors are sub-classified as luminal A, luminal B, HER2 expressing, basal-like and null type according to their hormonal status with cerbB2, CK 5/6 and EGFR expressions...

Most of the in vitro studies using liver cell lines have been performed under atmospheric oxygen partial pressure (21% O2). However, the oxygen concentrations in the liver and cancer cells are far from this value. In the present study, we have evaluated the influence of oxygen on 1) the tumor cell lines features (growth, steady-state ROS levels, GSH content, activities of antioxidant enzymes, p66 Shc and SOD expressions, metalloproteinases secretion, migration, invasion, and adhesion) of human hepatocellular carcinoma cell lines, and b) the response of the cells to an oxidant stimulus (aqueous leaf extract of the V...
