Carcinosarcomas are rare but aggressive neoplasms commonly described in organs such as the breast, urinary bladder, uterus, liver, and lungs. Histopathologically, they are characterized by the presence of malignant epithelial and mesenchymal components. The exact histogenesis of carcinosarcomas remains unknown and is debated in the literature. Primary carcinosarcomas of the skin are uncommon. To our knowledge, 20 cases of primary cutaneous carcinosarcoma have been described in the world literature. Most of these tumors were seen on the head and neck region of older individuals, both male and female. Microscopically, the more common carcinoma component is a squamous cell carcinoma followed by basal cell carcinoma, whereas the most common sarcoma component is an osteosarcoma. We report an example of this rare entity and speculate on its histogenesis in the skin.

Scleromyxedema (SM) is a rare primary cutaneous mucinosis characterized by systemic papules and scleroderma-like manifestations, often associated with monoclonal gammopathy. We present the case of a 37-year-old male with SM who developed yellowish plaques on the neck and back over three years. Histopathological examination revealed mucin deposition, fibroblast proliferation, and fibrosis, supporting the diagnosis.

Skin serves as the first-order protective barrier against the environment and any significant disruptions in skin integrity must be promptly restored. Despite significant advances in therapeutic strategies, effective management of large chronic skin wounds remains a clinical challenge. Dermal fibroblasts are the primary cell type responsible for remodeling the extracellular matrix (ECM) in wound healing.

Unlabelled: A 3D in vitro model of innervated skin would be a useful tool in dermatological research to study the effect of different chemicals and compounds on the sensory properties of skin. Current innervated skin models are limited in composition and often composed of ex vivo skin explants and/or animal-derived material. In this study, our aim was to develop a human innervated skin model with a better biomimicry composition for in vitro research.

The purpose of this phase I study was to define the safety and efficacy of botensilimab (BOT), an Fc-enhanced anti-cytotoxic lymphocyte-association protein-4 antibody, plus balstilimab (BAL), an anti-PD-1 antibody, in advanced sarcomas.
Methods: BOT was administered intravenously (IV) at 1 mg/kg or 2 mg/kg once every 6 weeks in combination with BAL IV at 3 mg/kg once every 2 weeks for up to 2 years.

Lymphomatoid papulosis (LyP) is currently categorized as a primary lymphoproliferative disorder that follows a chronic, recurrent clinical course. The diagnosis of LyP is mainly based on clinical presentation and histopathological correlation. Six subtypes of LyP have been described and recognized, each with different histological features and sometimes distinct clinical presentations.
