Merkel cell carcinoma is a rare form of skin cancer. It is usually very aggressive and metastasizes rapidly with a high mortality rate.

We discuss an unusual presentation of 65-year-old female who presented with anemia secondary to blood loss from an exceptionally large fungating axillary mass due to metastatic Merkel cell carcinoma requiring multiple transfusions.
