Early diagnosis of malignant skin cancer from images is a significant part of the cancer treatment process. One of the principal purposes of this research is to propose a pipeline methodology for an optimum computer-aided diagnosis of skin cancers. The method contains four main stages. The first stage is to perform a preprocessing based on noise reduction and contrast enhancement. The second stage is to segment the region of interest (ROI). This study uses kernel fuzzy C-means for ROI segmentation. Then, some features from the ROI are extracted, and then, a feature selection is used for selecting the best ones. The selected features are then injected into a support vector machine (SVM) for final identification. One important part of the contribution in this study is to propose a developed version of a new metaheuristic, named neural network optimization algorithm, to optimize both parts of feature selection and SVM classifier. Comparison results of the method with 5 state-of-the-art methods showed the approach's higher superiority toward the others.

Background: Keratoacanthoma is a relatively rare skin tumor, with vulvar keratoacanthoma being even more uncommon. Although the majority of keratoacanthomas exhibit a benign course, a subset of cases may show features of malignant potential, such as marginal invasion and recurrence.
Case: An 82-year-old female presented with a rapidly growing exophytic lesion on the left vulva, measuring 1.

Microcystic adnexal carcinoma (MAC) is a rare, slow-growing, locally aggressive malignant, and recurring appendageal tumor. Prolonged UV exposure, immunosuppression, and radiotherapy are a few frequently associated risk factors. MAC classically presents as an asymptomatic skin coloured plaque on the face.

Numerous clinical trials have established that various biologic and oral small-molecule therapies are efficacious in patients with psoriasis. However, as there are limited head-to-head trials, healthcare providers may compare results across multiple trials when providing treatment recommendations. Direct comparisons among agents are challenging because psoriasis trials differ in terms of study design, patient population, and data analysis methodologies.

Adjuvants play a central role in enhancing the immunogenicity of otherwise poorly immunogenic vaccine antigens. Combining adjuvants has the potential to enhance vaccine immunogenicity compared with single adjuvants, although the cellular and molecular mechanisms of combination adjuvants are not well understood. Using the influenza virus hemagglutinin H5 antigen, we define the immunological landscape of combining CpG and MPLA (TLR-9 and TLR-4 agonists, respectively) with a squalene nanoemulsion (AddaVax) using immunologic and transcriptomic profiling.

Multinucleate cell angiohistiocytoma (MCAH) is a rare benign cutaneous entity. It classically presents as slowly progressive erythematous to violaceous papules on the distal extremities of middle-aged or elderly women. The entity may clinically resemble granuloma annulare, lichen planus, and several cutaneous vascular proliferations.
