[Effective treatment of recurrent keratoacanthoma using methotrexate]

Three patients, two men aged 54 and 72 years, respectively, and a woman aged 52 years, were treated successfully for (recurrence of a) keratoacanthoma with methotrexate. Since the sixties 11 patients with recurrent keratoacanthoma treated with methotrexate have been described. Dose schedules were widely different and dosages were in general high, resulting in more or less severe side effects. The patients now presented were treated according to the Weinstein schedule, with small doses and during a short period, which minimises the adverse effects.
