Several malignant lesions have been reported in association with tattoos, including basal cell carcinomas, squamous cell carcinomas and melanoma. We report a keratoacanthoma arising in a recent tattoo. A 60-year-old woman presented with a tumor on her right leg, over an area of red pigment in a professional tattoo. Histological analysis confirmed the clinical diagnosis of keratoacanthoma. Although the association between malignancy and tattoos is very uncommon dermatologists and dermatologic surgeons should be attentive to this possibility.

Immune checkpoint blockade (ICB) has significantly improved the survival for many patients with advanced malignancy. However, fewer than 50% of patients benefit from ICB, highlighting the need for more effective immunotherapy options. High-dose interleukin-2 (HD IL-2) immunotherapy, which is approved for patients with metastatic melanoma and renal cell carcinoma, stimulates CD8 T cells and NK cells and can generate durable responses in a subset of patients.

Introduction: Adenoid basal cell carcinoma is a rare cervical malignancy which is indolent in nature but resembles more commonly occurring aggressive malignancies.
Cases: Here we describe three cases of cervical adenoid basal cell carcinoma. All patients had a history of cervical dysplasia with high-risk HPV.

Current approaches to oral cancer diagnosis primarily involve physical examination, tissue biopsy, and advanced computer-aided imaging techniques. However, despite these advances, patient survival rates have not significantly improved. Hence, there is a critical need to develop minimally invasive tools with high sensitivity and specificity to improve patient survival and quality of life.

The article explores celery-derived extracellular vesicles (CDEVs), characterized by high cellular uptake, low immunogenicity, and high stability, as a therapeutic strategy for antitumor nanomedicines. The methods employed in this study include cell experiments such as co-culture, Western Blot, and flow cytometry. experiments were conducted in C57BL/6 tumor-bearing mice subcutaneously injected with Lewis lung carcinoma (LLC) cells.
