title: [Bilateral leg ulcers with pathologic evidence of small vessel vasculitis by skin biopsy during hydroxyurea therapy of chronic myelogenous leukemia].
abstract: We report a 45-year-old male with chronic myelogenous leukemia (CML) who experienced skin ulcers of the left lateral malleolus and dorsum of both feet. He had been treated with hydroxyurea (HU) for 2 years. His leg ulcers improved after HU was discontinued. Skin biopsy of the ulcerated lesion revealed that the lesion is compatible with small vessel vasculitis, but circulating immune complexes (C1q, anti-C3d antibody) were negative. Although the precise mechanism of the skin ulcer is unknown, we must take into consideration the skin changes were secondary to hydroxyurea therapy in myeloproliferative disorders.
