  • Pathology

Background:

  • Merkel cell tumors are rare neuroendocrine skin neoplasms originating from Merkel cells.
  • These tumors typically present as rapidly growing, painless nodules on sun-exposed skin.

Observation:

  • This report presents two unique Merkel cell tumor cases.
  • Case 1: A collision tumor involving Merkel cell carcinoma and basal cell carcinoma, a presentation previously unreported.
  • Case 2: A Merkel cell tumor on the digit of a black female, a rare occurrence in this demographic and location.

Findings:

  • The first documented instance of a collision tumor between Merkel cell carcinoma and basal cell carcinoma.
  • The second reported case of Merkel cell carcinoma in a black female, and the first occurring on a digit.
