Merkel cell cancer, also known as Merkel cell carcinoma, is a rare and aggressive form of skin cancer that originates from Merkel cells, which are involved in touch sensation. It typically appears as a painless, firm, and rapidly growing nodule on sun-exposed skin, primarily affecting older adults and those with weakened immune systems. The cancer is often linked to the Merkel cell polyomavirus and excessive sun exposure. Due to its aggressive nature, it has a higher propensity for metastasis compared to other skin cancers.
