Adriamycin Chemotherapy Melanoma Or Medication?

Melanoma or Medication? - adriamycin chemotherapy

I am in a patient with breast cancer. I just finished 4 rounds of adriamycin and cytoxan chemotherapy. I started the taxol Friday. There are about a month ago I noticed a dark spot on my left finger. Now it is dark brown and extends into the nail a little. Not in the nail underneath. He also developed the same spots on the tongue. Cytoxan side effects can the blackening of the nails, but can range from a nail or nail changes are isolated all? Do you think that either of chemotherapeutic agents?
