Hand-foot hyperpigmentation skin lesions associated with combination gemcitabine-carboplatin (GemCarbo) therapy.
Gemcitabine (Gemzar) is a nucleoside analogue used as a cytotoxic agent for the treatment of various carcinomas: pancreatic cancer, bladder cancer, breast cancer, and non-small-cell-lung cancer. Carboplatin, a DNA alkylating agent, is used alongside with gemcitabine in a regimen known as GemCarbo chemotherapy to treat several different types of cancer, most commonly lung cancer. We report an unusual case of hand-foot hyperpigmentation after the use of GemCarbo therapy on a man with stage IV non-small cell lung carcinoma. Physical examination revealed hyperpigmented lesions that were approximately 1-2 mm in diameter, of brown/purple discoloration localized to the palmar surface of his hands and the dorsum of his feet. A rapid plasma reagin blood test, used for the screening of syphilis was nonreactive. Discontinuation of both agents resulted in the dramatic disappearance of the lesions over the course of 2 weeks. In this report, we describe, to our knowledge, the first case of hand-foot hyperpigmentation that has been reported with the use of either of these 2 agents.
