Plain-English summary

A 9-year-old Boston terrier was brought to the vet with skin bumps and lesions caused by a rare infection from a type of bacteria called Mycobacterium goodii. The dog also had Cushing's disease, which can lead to skin problems. The vet treated the infection with antibiotics doxycycline and ciprofloxacin for about 9 months, while also managing the Cushing's disease with mitotane therapy. After treatment, the dog showed no signs of the infection for 14 months, indicating a successful outcome.

Abstract

Abstract A 9-year-old Boston terrier was diagnosed with multifocal, nodular panniculitis caused by an organism belonging to the Mycobacterium smegmatis group by histological evaluation and bacteriological identification. The mycobacterial species was identified by direct gene sequence analysis and confirmed to be Mycobacterium goodii. Treatment using doxycycline and ciprofloxacin was successfully implemented for the mycobacterial panniculitis over a period of 9 months. Concurrent pituitary-dependent hyperadrenocorticism (Cushing's disease) was also identified using routine diagnostic methods and mitotane therapy was implemented. There was follow-up for 14 months after cessation of antimicrobial therapy with no recurrence of mycobacterial infection. Although cutaneous infections are frequently recognized as complications of canine pituitary-dependent hyperadrenocorticism, concurrent mycobacterial panniculitis due to any rapidly growing mycobacterium has not previously been reported. This is the first confirmed case of mycobacterial panniculitis due to M. goodii infection in a dog and also the first of any rapidly growing mycobacterial infection in a dog with concurrent endogenous Cushing's disease.
