Capecitabine induced cutaneous hyperpigmentation: report of a case.

We report an unusual case of cutaneous and mucosal hyperpigmentation in a thirty-six year old African American woman who was receiving capecitabine chemotherapy for Stage IV breast carcinoma. Possible etiologies for the hyperpigmentation are discussed. To our knowledge, this is the first reported case of capecitabine associated cutaneous hyperpigmentation.
