Merkel cell carcinoma, also called neuroendocrine carcinoma of the skin or trabecular cancer, is a very rare type of skin cancer that forms when Merkel cells grow out of control.

How fast does Merkel cell carcinoma spread?

A lesion of metastatic MCC may appear as a 1-3 cm, flesh-colored to red-purple bump that feels firm, is deeper compared to the primary lesion, and grows rapidly over a period of 2-4 weeks.

Is Merkel cell cancer fatal?
