5 Facts you should know about

Merkel cell carcinoma

Merkel cell carcinoma (MCC) usually presents as a firm nodule (up to 2 cm diameter) or mass (>2 cm diameter)

They are flesh-colored, red, or blue tumors typically, vary in size from 0.5 - 5 cm in diameter - and often enlarge rapidly

Although MCC may arise almost anywhere on the body, it is most commonly found in sun-exposed areas such as the head, neck, or extremities

Merkel-cell cancers tend to invade locally, infiltrating the underlying subcutaneous fat, fascia, and muscle, and typically metastasize early in their natural history

It is more common in people over 60 years old, Caucasian people, and males
