[Inflammation of multiple seborrheic keratoses induced by chemotherapy with gemcitabine].

There are several common mucocutaneous adverse effects related to chemotherapy, either by direct cytotoxic action or by hypersensitivity to the drugs. The authors report inflammation in multiple seborrheic keratoses after chemotherapy with gemcitabine in a patient under treatment for pancreatic cancer. Moreover, they discuss the relative benignity of this event and warn about the need to correctly identify systemic chemotherapy-induced skin adverse effects.
