Merkel Cell Carcinoma

Merkel cell carcinoma is a rare but aggressive form of skin cancer that originates from Merkel cells, which are touch-sensitive cells located in the skin. It often appears as a rapidly growing, painless, firm, and shiny or bluish lump, usually on sun-exposed areas like the face or neck. The cause is linked to sun exposure and a virus called Merkel cell polyomavirus. Because it can spread quickly, early diagnosis and treatment—typically surgery, radiation, or chemotherapy—are essential for better outcomes. Regular skin checks are important for early detection, especially for those at higher risk.
