Trichomegaly induced by topical tacrolimus for the treatment of periorbital vitiligo: A brief report of a new adverse effect.

Abstract

Trichomegaly is a known adverse effect of systemic administration of cyclosporine but is less commonly associated with systemic tacrolimus or with topical calcineruin inhibitors. In this report, we describe the first case, to our knowledge, of trichomegaly due to long-term use of topical tacrolimus for periocular vitiligo.
