Primary angiosarcoma of the breast is a rare malignant tumor. We report a case of breast primary cutaneous angiosarcoma in a patient with a strong family history of malignancy. For definitive diagnosis, a tissue biopsy is needed, with immunostaining for the presence of blood vessel endothelial markers CD31 and CD34. Total mastectomy is the preferred method of surgical treatment. Chemotherapy has not been shown to increase overall survival, but in some instances it may improve local control and disease-free survival. Surgery combined with radiation may increase local control, but patients at high risk of recurrence may benefit from adjuvant treatment as well. We discuss the potential benefits from various treatments for primary cutaneous breast angiosarcoma.

Merkel cell carcinoma (MCC) is diagnosed through histopathological and immunohistochemical examination of biopsies from skin or other organs. Its distinguishing features include perinuclear dot-like staining with Cytokeratin 20 (CK20) and detection of Merkel cell polyomavirus (MCPyV) using various methods. However, CK20 and MCPyV negative MCC cases have been reported at varying rates.

Background: Primary tumor thickness is important for prognosis of melanoma patients. To enhance prevention and quantify the true burden of melanoma, better understanding of thickness patterns and associated characteristics is crucial. Previous studies have been limited to report trends and address risk factors of thickness in specific melanoma subtypes in the Greek population.

Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a type of skin T-cell lymphoma with a favorable prognosis. Some patients may experience recurrence, but systemic involvement is rare. Some studies suggest that systemic progression is associated with poor prognosis.

Introduction: Inflammasomes NLRP1 (NLR family pyrin domain containing 1) and NLRP3 are pivotal regulators of the innate immune response, activated by a spectrum of endogenous and exogenous stressors, including ultraviolet radiation (UVR). The precise molecular mechanisms underlying the activation of these inflammasomes remain unclear. Furthermore, the involvement of interleukin-33 (IL-33) in UVR-induced skin carcinogenesis is not well defined.

Introduction: Little is known about the day-to-day variability of different skin microcirculation parameters, and how this variability is influenced by age and sex. The aim was to examine the day-to-day variability of microcirculatory parameters in relation to age and sex.
Methods: The cutaneous microcirculation was measured using a fiber optic probe integrating laser Doppler flowmetry (LDF) and diffuse reflectance spectroscopy (DRS) to measure oxygen saturation, red blood cell (RBC) tissue fraction, speed-resolved and conventional perfusion.
