Multidrug-resistant Nocardia pseudobrasiliensis presenting as multiple muscle abscesses

Vimalkumar Veerappan Kandasamy et al. BMJ Case Rep. .

Abstract

A 79-year-old Caucasian man presented with multiple leg abscesses due to Nocardia pseudobrasiliensis. He was on chronic steroid therapy for myasthenia gravis. We present the difficulties in diagnosis and treatment of this rare organism. N. pseudobrasiliensis is a new emerging species that was previously thought to belong to the N. brasiliensis species. The distinction between the two species is extremely important given the different antibiotic susceptibility pattern and association of N. pseudobrasiliensis with more invasive and disseminated disease.
