Tegafur is a fluoropyrimidine analog of fluorouracil with a similar spectrum of antitumor activity. It is used in the treatment of advanced gastrointestinal neoplasms. Tegafur seems to have a lower rate of hematologic toxicity than fluorouracil and has been used as an alternative oral therapy to intravenously administered fluorouracil. The most common side effects are nausea and vomiting. Although some cases of cutaneous toxic effects have been reported,1,2 in most clinical studies with oral tegafur they are only referred to as ''dermatitis'' or pigmentation and no other details are given.
We report a case of palmoplantar keratoderma resulting from a chronic acral erythema due to oral tegafur. To our knowledge, this cutaneous reaction has not been previously reported as a side effect of tegafur therapy.
