Development of metastatic Merkel cell carcinoma following the excision of same‐sided recurrent auricular melanoma

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 patient with the history of recurrent malignant melanoma of the right pinna and subsequent excision. Three years following the excision of melanoma, he presented with a lesion to the right forehead as well as a right‐sided neck mass that were found to be metastatic Merkel cell carcinoma.
