[Leg ulcers in patient affected by polycythemia vera in treatment with hydroxycarbamide. Case report].
Leg ulcers are a frequent and serious complication of polycythemia vera (PV). They are caused by a synergic action of vascular, neurological and infectious physiopathologic mechanisms. Furthermore, cytostatic therapies commonly employed to control the myeloproliferative disease negatively interfere on the development of granulation tissue, slowing down the recovery of the ulcer. We describe the case of a 70 years old woman with PV, who had calcaneous and perimalleolar ulcers. They were so painful that they made it almost impossible for her to sleep and walk normally. These ulcers were particularly resistant to common topical therapy. Further and accurate investigations showed that these ulcers were a complication of hydroxycarbamide therapy employed and they were not a complication of the ematologic disease. Leg ulcers during hydroxycarbamide therapy are a relatively frequent but underestimated condition. Pathogenesis is bound to numerous factors, i.o. cellular damage and tissutal hypoxia, consequent of drug induced macroerythrosis. In our patient drug substitution and prosecution of topic therapies allowed the recovery of the leg ulcers, particularly serious for both, extensiveness and symptoms.
