Infectious Granuloma With Mycobacterium abscessus After Facial Injection of Botulinum Toxin: A Case Report

Abstract

Botulinum toxin injections have garnered increasing employment in facial rhytidectomy due to their demonstrable efficacy and safety profile. In this study, the authors present the case of a 39-year-old woman who manifested painful crimson nodules and multiple abscesses on her face, which manifested 1 week postinjection. Subsequent histopathological scrutiny unveiled the development of histiocytic granulomas accompanied by infiltrates of inflammatory cells, and microbiological investigation and polymerase chain reaction assays identified the causative agent as Mycobacterium abscessus.
