Merkel cell carcinoma (MCC) is a rare neuroendocrine malignancy of the skin that is highly aggressive and often metastasizes early. MCC is diagnosed based on histopathological findings and is most commonly treated with surgical resection, which may be accompanied by chemotherapy and/or radiation. This report describes a 55-year-old male with history of recurrent malignant melanoma of the right pinna and subsequent excision. Three years following the excision of melanoma, he presents with a lesion to the right forehead as well as a right-sided neck mass that were found to be metastatic Merkel cell carcinoma. Although there have been reports describing the development of second cancers following the treatment of MCC, the development of MCC after the treatment of other malignancies has not been well-described. Merkel cell carcinoma remains a highly aggressive and frequently metastatic malignancy that should not be overlooked, especially when developed after the diagnosis and treatment of other primary cutaneous malignancies such as melanoma.
