Gottron's papules-like eruption developing under hydroxyurea therapy.

A 57-year-old white female developed a Gottron's papules (GP)-like eruption, without any of the other clinical or laboratory signs of dermatomyositis (DM). She was under hydroxyurea treatment for chronic myeloid leukemia at the time. Skin biopsy was compatible with seborrheic keratosis. Conditions presenting with GP but unrelated to DM are reviewed, with emphasis on hydroxyurea-induced skin lesions.
