Merkel cell tumor: two cases

Merkel cell tumors are rare skin lesions that arise from the Merkel cell in the dermal layers. The two cases presented in this report are important in that they add more information to the literature than previously had been recognized. The first case discusses a collision tumor with a basal cell carcinoma. This is the first such report of this type of collision tumor. The second report is of a black female with a Merkel cell tumor of her finger. The case is unusual in that it is only the second time that a black female is reported to have this disease and the first time that it is reported on a digit. A review of the literature accompanies these case reports.
