Pseudomonas aeruginosa is usually isolated from chronic skin ulcers such as bed sores, but it can rarely cause cellulitis and, more rarely, facial cellulitis.1- 4 While P aeruginosa has low to moderate virulence in healthy patients, in immunocompromised subjects, such as those with neutropenia, it acts as an opportunistic pathogen with severe and life-threatening complications. We report the case of a previously healthy woman who was seen with an ecthyma gangrenosum and severe facial cellulitis following carbimazole-induced agranulocytosis.
