Merkel Cell Carcinoma

Merkel cell cancer is also known as neuroendocrine cancer of the skin, or trabecular cancer. Characterized by firm, shiny skin lumps, this rare cancer develops on or just beneath the skin and in the hair follicles. Merkel cell cancer most often is found on sun-exposed areas of skin, such as the neck and head. The cancer mostly affects white people over the age of 50. The cause of the cancer is unknown, but it is believed to be related to both sun exposure and suppression of the immune system.
