What is Merkel Cell Carcinoma?
Merkel cell carcinoma is an aggressive form of skin cancer that usually appears as a flesh-coloured or bluish- or purplish-red nodule, often on the skin of the face, head, neck, or less often on the legs or arms, though it may occur anywhere. Its name comes from the fact that these cancer cells are derived from the normal Merkel cells in the skin associated with sensation of touch. These normal, non-cancerous Merkel cells were first described in 1875 by German physician, Friedrich Sigmund Merkel (Ramahi, et al., 2013).
