PURPOSE: The purpose of the study was to evaluate the characteristics of sebaceous gland carcinoma (SGC) of the ocular adnexae, which is due to a high variability in clinical, histological and immunohistochemical characteristics often challenging to diagnose. METHODS: Records of six patients with SGC were reviewed, who underwent surgical excision and who were histologically diagnosed with SGC. For comparison, there were specimens from four patients with basal cell carcinoma (BCC) and four patients with squamous cell carcinoma (SCC)...

Malignant changes arising on the previously traumatized or chronically inflamed skin are defined as Marjolin ulcers. They can develop on many different lesions but frequently they are detected on burn scars. Histopathologically, Marjolin ulcers are mostly diagnosed as squamous cell carcinoma and they need special attention when especially located on the lower extremities. In this study, 63 patients treated for Marjolin ulcers between January 2000 and March 2015 were evaluated according to etiology, histological differentiation, primary tumor size, patient age and anatomical localization...

Dusingize et al. used a prospective observational cohort study to demonstrate a decreased risk of basal cell carcinoma and an increased risk of squamous cell carcinoma among smokers. This association disappeared after stratifying for skin screening visits, demonstrating the important role of detection bias. In the absence of randomized clinical trials, well-designed and critically analyzed observational studies can provide similarly valuable evidence.

PURPOSE OF REVIEW: Recent advances in the treatment of eyelid tumors have centered on the excision, evaluation of margins, role of sentinel lymph node biopsy, and adjunctive/adjuvant systemic and radiation therapy. The purpose of this review is to elaborate on these advances. RECENT FINDINGS: Mohs excision of basal cell carcinoma and squamous cell carcinoma continues to provide the greatest success in complete excision of the cancer, especially in those cases of high-risk disease including medial canthal location and recurrent disease...

BACKGROUND: Recent studies have indicated that serum levels of squamous cell carcinoma antigen (SCCA) 1 and 2 induced by type 2 cytokines such as IL-4 and IL-13, are increased in patients with atopic dermatitis (AD). However, no clinical studies have analyzed serum levels of SCCA2 in larger series of AD patients or their association with various clinical characteristics. This study was performed to clarify whether serum levels of SCCA2 are associated with disease severity and clinical phenotypes of adult AD patients...

BACKGROUND: Jeju Island is geographically and socioeconomically distinct from the mainland of South Korea. Thus, the presentation and management of non-melanocytic skin cancers (NMSC) of the head and neck may differ from those in other regions of the country. We compared the clinical characteristics and treatment modalities of NMSC on Jeju Island with the findings of similar regional studies. METHODS: Patient data, including age, sex, diagnosis, tumor site, treatment, and recurrence, were obtained from the medical and pathology records of patients diagnosed with NMSC between January 2010 and June 2015...

REVIEW

Papillomaviruses (PVs) cause disease in both dogs and cats. In dogs, PVs are thought to cause oral papillomatosis, cutaneous papillomas and canine viral pigmented plaques, whereas PVs have been rarely associated with the development of oral and cutaneous squamous cell carcinomas in this species. In cats, PVs are currently thought to cause oral papillomas, feline viral plaques, Bowenoid in situ carcinomas and feline sarcoids. Furthermore, there is increasing evidence that PVs may also be a cause of cutaneous squamous cell carcinomas and basal cell carcinomas in cats...

Photodynamic therapy (PDT) is an effective treatment for actinic keratoses and early skin cancers, and the only office procedure to control field cancerization. Procedure-associated pain limits widespread PDT use and by early termination of treatment can decrease overall therapeutic efficacy. Here we review and assess reported interventions on PDT-associated pain, in order to identify the most promising methods to manage treatment-associated pain and identify focus for future studies. Literature search was performed using MEDLINE, EMBASE, and the Cochrane Library by two independent reviewers to select publications that assessed and compared pain quantitatively during PDT treatment for actinic keratoses, basal cell carcinomas, and/or in situ squamous cell carcinomas...

Non‑melanoma skin cancer (NMSC) is the most common form of cancer worldwide, comprising 95% of all cutaneous malignancies and approximately 40% of all cancers. In spite of intensive efforts aimed towards awareness campaigns and sun‑protective measures, epidemiological data indicate an increase in the incidence of NMSC. This category of skin cancers has many common environmental triggers. Arising primarily on sun‑exposed skin, it has been shown that ultraviolet radiation is, in the majority of cases, the main trigger involved in the pathogenesis of NMSC...

Sun exposure is the main cause of squamous (SCC) and basal cell carcinoma (BCC) although pattern and amount differ by cancer type, and sun sensitivity is the major host risk factor. Our study investigated risk factors and residential ambient UV in a population-based sample of Australian 45 and Up Study participants: 916 BCC cases, 433 SCC cases, 1224 controls. Unconditional logistic regression models adjusting for key covariates demonstrated 60% increased BCC risk and 2-fold increased SCC risk with sun sensitivity, and 3- and 4-fold increased risk respectively with solar keratoses...

This article focuses only on margin analysis of the cutaneous malignancy of the skin. It discusses basal cell carcinoma, squamous cell carcinoma, and cutaneous melanoma. The management of the neck and distant disease are beyond the scope of this article, but it answers what is the appropriate surgical margin when excising these skin tumors, whether frozen sections are accurate for the analysis of these tumors, and treatment algorithm and rationale for a positive resection margin.

Importance: Persons with human immunodeficiency virus (HIV) have a 2.8-fold higher risk than HIV-uninfected persons of nonmelanoma skin cancer (NMSC), defined as basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Individuals with a prior NMSC history are at increased risk for subsequent NMSC, but the magnitude of risk and its relation to HIV disease-related factors, including CD4 count and viral load (VL), are unknown. Objective: To better understand how laboratory markers currently used to evaluate HIV disease progression may be associated with subsequent NMSC risk...

Adenosquamous carcinoma (ASC) of the gallbladder is a rare malignant tumor that is characterized by a coexisting of glandular and squamous components. In a case of ASC, we performed hotspot multigene mutational profiling of 164 hotspot regions of eleven cancer-associated genes (AKT1, APC, BRAF, CTNNB1, KIT, KRAS, NRAS, PDGFRA, PIK3CA, PTEN and TP53) in the two microdissected components. Both tumor phenotypes resulted characterized by a p.E542K point mutation in the PIK3CA gene, whereas adenocarcinoma component revealed also a TP53 Q331* homozygous stop mutation...

We investigated the expression of FOXC2, PinX1, Ki-67 and Cyclin D1 in cutaneous cell carcinoma. We collected 30 cutaneous squamous cell carcinoma (SCC), 30 cutaneous basal cell carcinoma (BCC) and 30 normal skin tissues. The protein expression and gene expression of FOXC2, endogenous telomerase-inhibiting gene PinX1, Ki-67 and Cyclin D1 was measured by immunohistochemistry (IHC) and semi-quantitative reverse transcription polymerase chain reaction (RT-PCR), respectively. In SCC and BCC tissues, the positive rate of protein expression and mRNA level of PinX1 were both significantly lower than those in normal tissues...

BACKGROUND: In considering skin cancer, a number of factors - including effectiveness, simplicity of treatment, cost, and aesthetic outcomes - are important to ensure patient satisfaction. There are several existing interventions, such as electrodessication and curettage, excision, Mohs surgery, radiation therapy, cryotherapy, and topical/oral treatments. Laser therapy has emerged as a new promising alternative that should be explored. OBJECTIVE: To review the dermatologic literature on the use of laser therapy in the treatment of skin cancer...

The nose is a critically important aesthetic and functional portion of the face. We can explore nasal defects following trauma or tumor resections. Reconstructive techniques based on primary closure, skin graft, local flap, regional flap and microvascular free tissue transfer provides an algorithmic framework applicable to any reconstructive problem. From 2010 to 2016, 33 patients were treated with nasal reconstruction. Malignant tumor resection was the main cause of nasal defect. The most common tumor resected was BCC (basal cell carcinoma) followed by SCC (squamous cell carcinoma)...

AIMS: Terminal deoxynucleotidyl transferase (TdT) is a DNA polymerase expressed in immature, normal and neoplastic, lymphoid or hematopoietic cells and in neuroendocrine carcinomas, like Merkel cell carcinoma and small cell carcinoma. It has not yet been described in cells of epithelial origin. After observing TdT immunoreactivity in normal sebaceous glands we analyzed its spectrum of expression in cases of sebaceous cell hyperplasia and sebaceous cell neoplasms. METHODS & RESULTS: Twelve cases of sebaceous gland hyperplasia (SGH), and three cases of other benign lesions, namely, sebaceoma, sebaceous adenoma and sebaceous nevus, along with four archived cases of sebaceous cell carcinomas (SC) were collected and stained with TdT antibody...

Non-melanoma skin cancer (NMSC), including basal cell and squamous cell carcinomas, is the most common form of neoplasm. The incidence of NMSC is increasing worldwide. The cure rate is high with early detection and appropriate treatment. Visual examination is the first screening tool used by clinicians, but it is sometimes not sufficient to discriminate benign from malignant lesions. Skin biopsy with histopathology is the gold standard for differential diagnosis; however, this procedure is invasive and occasionally painful...
