Use of topical rapamycin in acral pseudolymphomatous angiokeratoma of children (APACHE): A report of two cases and review of the literature

Abstract Acral pseudolymphomatous angiokeratoma of children (APACHE) is a rare, benign disease characterized clinically by multiple, asymptomatic, erythematous papules in the acral regions. We report APACHE in a 12‐year‐old girl with erythematous‐violaceous papules on the lateral dorsum of her foot and toes, and a 3‐year‐old girl with erythematous papules on the plantar aspect of her foot. Topical rapamycin ointment improved the lesions and both patients tolerated the medication well. Topical rapamycin appears to be a potentially efficacious, well‐tolerated, non‐invasive therapy in APACHE, although further studies are needed.
