The patient underwent partial petrosectomy to completely remove the lesion as CT and MRI scans showed an infiltrative process. Squamous carcinoma was the final histological diagnosis. The patient was disease free at 1 year of follow-up after petrosectomy. In conclusion, if there are inconsistencies between clinical observation and histological report, additional tests should be performed to exclude the malignity of a lesion.

Analysis of Raman spectroscopy data with algorithms based on paraconsistent logic for characterization of skin cancer lesions. Analysis of the Raman data to obtain results in discrimination models is usually done with multivariate statistics based on principal component analysis PCA. In this work, we present a technique based on a non-classical logic called In this work, we present a technique based on a non-classical logic called paraconsistent logic PL.

The aim of this work is to use computational procedures capable of generating efficient expert systems to discriminate cutaneous tissue samples obtained by Raman spectroscopy. Data processing, pattern creation, and comparisons were performed using the set of paraconsistent algorithms SPA-PAL2v. The total number of samples was divided into four histopathological groups, with spectra of basal cell carcinoma BCC , 21 spectra of squamous cell carcinoma SCC , 57 spectra of actinic keratosis AK , and 30 normal skin NO spectra.

Two analyses were performed. Arnaldo Carvalho. Methylthioadenosine MTA inhibits melanoma cell proliferation and in vivo tumor growth. In the proposed work complete task is divided in three parts. First is preprocess and segment the image. After segmentation different features texture, color, higher order spectra HOS have been extracted. These extracted features are These extracted features are applied for for the classification. Performances of five different algorithms are compared in terms of accuracy, meantime, min-time and max-time.

The accuracy of the proposed technique is In the present work a dataset of images of melanoma is used for the classification in which for training and for testing. Fungi in the genus Malassezia are involved in skin disorders, including dandruff and seborrheic dermatitis, two commonly recurring scalp conditions that are often treated with selenium-containing materials.

The antifungal effects of SeS Both preparations were more effective against M. Post-antifungal effects were not observed for M. Brief exposure of Malassezia spp. Cutaneous horn in a sun-protected site harbouring unusual malignancy. Cutaneous horns are conical, circumscribed projections formed by desquamation and layering of keratin. Although they can appear on the skin anywhere on the body, they are most commonly seen on the sun-exposed surfaces, and are often Although they can appear on the skin anywhere on the body, they are most commonly seen on the sun-exposed surfaces, and are often associated with solar keratosis.

Cutaneous horns are most often benign, however they are a potential site of malignancy and may harbor premalignant or malignant lesions, the most common being squamous cell carcinoma, the causal relationship being straightforward and both squamous cell carcinoma and cutaneous horns can be equated with the common epithelial maker keratin. Other histological types of malignancies are not usually noted in conjunction with cutaneous horns.

Here we describe a patient with a cutaneous horn over the volar aspect of the right forearm, a sun-protected site, harbouring basal cell carcinoma, an infrequent finding.

Research on the biological activities of essential oilsin human skin cells is limited. This study first analyzed the effect of an essential oil blend EOB on 17 important protein biomarkers in cytokine-stimulated human dermal This study first analyzed the effect of an essential oil blend EOB on 17 important protein biomarkers in cytokine-stimulated human dermal fibroblasts. It significantly increased vascular cell adhesion molecule 1 levels and slightly increased the monocyte chemoattractant protein 1 and epidermal growth factor receptor production.

We then studied the effect of the EOB on the expression levels of 21, genes in the same cells. We found that the EOB markedly affected genome-wide gene expression. Further analysis revealed that the EOB pleiotropically regulated multiple signaling pathways in human cells including hepatic fibrosis activation, antigen presentation, mitotic roles of the polo-like kinase, and cyclin and cell cycle regulation. Many pathways significantly affected by the EOB are closely related to inflammatory and immune responses. The results suggest that the EOB may affect biological processes and global gene expression in human skin cells.

Further research into the underlying mechanism of action of the EOB is needed. Traditional and ethnobotanical dermatology practices in Africa. Africa has a well-established history of botanicals use. These include a vast array of compounds that can be used to treat The researchers were also able to find out information regarding the participants' intake of vitamin A thanks to detailed surveys that the participants in the two study groups had filled out once every 4 years, approximately. Based on their analysis, the researchers found that participants who were on the higher end of the spectrum, in terms of vitamin A intake, seemed to have a lower risk of cutaneous squamous cell carcinoma.

Most of the vitamin A in these cases came from food sources, especially vegetables, not from dietary supplements, the researchers add. While the researchers note that their findings are a good start, in terms of understanding whether dietary factors may influence the risk of skin cancer, they also admit that the study faced some limitations. In particular, the authors cite "the homogeneity of the study population," which was made up almost exclusively of educated, white healthcare professionals.

They say that for a more inclusive study with more generalizable results, researchers should look at a more diverse population. Also, one study author reports potential conflicts of interest, having worked as a consultant for biopharmaceutical companies AbbVie and Amgen, pharmaceutical companies Janssen, Merck, Novartis, and Pfizer, as well as the Centers for Disease Control and Prevention CDC.

Despite any potential drawbacks in the study methodology, the researchers conclude that their findings, so far, support the notion that having an adequate intake of vitamin A could help prevent the development of skin cancer:. Our data further support the contention that supplemental and dietary vitamin A may be beneficial in preventing [squamous cell carcinoma].

Black people can get skin cancer, though it is less likely to affect them than people with lighter skin. For darker-skinned people, it usually occurs…. Fitzpatrick skin typing is a way of classifying different types of skin. What does a person's Fitzpatrick skin type tell us about their skin? Being able to recognize these diseases can result in early treatment and a better outlook. A rash can indicate mild irritation, or it could be a sign of skin cancer.
