Merkel Cell Carcinoma [ MCC ], also called neuroendocrine cancer, is a rare type of disease in which
malignant (cancer) cells are found on or just beneath the skin and in hair follicles. Merkel cell carcinoma usually appears as firm,
painless, shiny lumps of skin. These lumps or tumors can be red, pink, or blue in color and vary in size from less than a quarter of an
inch to more than two inches.
Merkel cell carcinoma is usually found on the sun-exposed areas of the head, neck, arms, and legs. This type of cancer occurs mostly in
whites between 60 and 80 years of age, but it can occur in people of other races and ages as well.
