Be watchful for any new or changing lesions on your skin and look out for these warning signs. If you've been treated for a previous MCC, pay close attention to the site and the surrounding region When this carcinoma spreads to the body, it metastasizes deep down to the bones and underlying tissues. It goes first to the lymph nodes and travels to adjacent tissues. If the carcinoma metastasize deeply, it is now harder to treat and can lead to death. Pictures of Merkel Cell Carcinoma

Merkel cell carcinoma (MCC) is a rare primary cutaneous neoplasm known for its propensity to develop early regional and distant metastasis. Fewer than 400 cases occur annually in the United States. MCC ranks as the most deadly of cutaneous malignancies, with a fatality rate of approximately 25%. Because of its aggressive nature, MCC is often resistant to surgery, radiation, and chemotherapy.
