Merkel-cell carcinoma
Merkel-cell carcinoma (MCC) is a rare and aggressive type of skin cancer that usually appears as a flesh-colored or bluish-red nodule, often on your face, head or neck. Merkel-cell carcinoma is also called neuroendocrine carcinoma of the skin.
Causes[edit | edit source]
MCC is believed to be caused by a combination of factors, including long-term sun exposure and a weakened immune system. The Merkel cell polyomavirus (MCPyV) is also associated with most cases of MCC.
Symptoms[edit | edit source]
The most common symptom of MCC is a fast-growing, painless nodule (bump) on your skin. The nodule may be skin-colored or may appear in shades of red, blue or purple. Most often, the nodule will appear on a sun-exposed area, such as your face, neck or scalp.
Diagnosis[edit | edit source]
Diagnosis of MCC often involves a skin biopsy, where a sample of the suspicious skin is removed and examined under a microscope. Other tests, such as imaging tests and sentinel lymph node biopsy, may also be used to determine the extent of the cancer.
Treatment[edit | edit source]
Treatment options for MCC include surgery, radiation therapy, and chemotherapy. In some cases, a combination of these treatments may be used. Immunotherapy is a newer treatment option that uses the body's immune system to fight the cancer.
Prognosis[edit | edit source]
The prognosis for MCC varies greatly depending on the stage of the disease at diagnosis. Early detection and treatment can significantly improve the prognosis.
