Dermatological Toxicity of Hydroxycarbamide

Abstract

Hydroxycarbamide is an antitumor agent mainly used for treatment of Ph-negative myeloproliferative disorders and sickle cell disease. The development of skin ulcers is a rare but serious adverse event in long-term antitumor therapy. Hydroxycarbamide-induced ulcers are often multiple and bilateral, and usually occur in the lower legs, although they can occur in other regions of the body. The ulcers are smallsized and shallow with sharp margins and yellow fibrine-covered base. They cause constant severe, difficult to treat pain which is a characteristic sign. The drug withdrawal usually leads to spontaneous healing of ulcers. Regular dermatologic screening must be obligatory for all the patients receiving hydroxycarbamide. The present paper provides a literature review on dermatological toxicity of hydroxycarbamide and a clinical case description.
