It was first described by Cyril Toker in 1972 who called it trabecular carcinoma. Later, it was named after the Merkel cells (specialized pressure receptor cells in the epidermis) as these are histologically and immunophenotypically like MCC tumor cells. MCC is most common in the 7th to 9th decades of life and frequently arises on chronically sun-exposed skin of the head and neck (>40%). Immunosuppression is also a risk factor with higher rates in patients with hematological malignancy, HIV, and iatrogenic immunosuppression.
