Treatment of Keratoacanthoma: Is Intralesional Methotrexate An Option?

Abstract

The results from the present retrospective study show that intralesional MTX injection is an effective treatment option for KAs. The authors propose that intralesional MTX injection with initial debulking of the KA should be used as a first line of treatment when KAs present on the extremities, in cosmetically sensitive areas and in elderly patients with multiple comorbities.
