Reactive angioendotheliomatosis presenting as cellulitis.

Reactive angioendotheliomatosis (RAE) is a diagnostically challenging condition characterized by multiple possible clinical presentations, which makes diagnosis challenging. We present a rare case of RAE mimicking cellulitis in a 74-year-old woman with a valvular disease and also end-stage renal disease, for which she was being treated with haemodialysis.
