Plain-English summary
A 25-year-old female yellow-naped Amazon parrot was brought in for a chronic, raised, ulcer on her left thigh. The vet found that the ulcer was caused by a type of infection called mycobacteriosis, which can also affect humans. The parrot was treated with antibiotics and anti-inflammatory medication, and after two weeks, the ulcer had healed. However, similar lesions appeared again on her right leg 14 months later, but the tests showed no signs of the infection. This case highlights the importance of monitoring for recurring skin issues in birds.

Abstract
An approximately 25-year-old, female, yellow-naped Amazon parrot () was evaluated for a chronic, raised, ulcerative mass on the lateral aspect of the left thigh. Histopathology of an excisional biopsy revealed severe, chronic, multifocal-to-coalescing, ulcerated dermal and subcutaneous granulomas. No infectious organisms were observed on Ziehl-Neelsen or Gomori methenamine silver stains. The parrot was treated with oral sulfamethoxazoletrimethoprim and meloxicam. When reexamined 2 weeks later, the biopsy site had healed. Surgical biopsies were resubmitted 14 months after the original presentation due to recurrence of similar ulcerative lesions on the right leg. Histopathology revealed a similar inflammatory pattern, and hematoxylin-eosin, Ziehl-Neelsen, and silver stains on the biopsy samples were all negative. A Fite-Faraco stain revealed rare acid-fast bacilli throughout the lesion. Tissue polymerase chain reaction test was negative forand. Mycobacterial culture and subsequent genotyping revealed.is a significant cause of mycobacteriosis in humans and, therefore, should be considered a potential zoonotic organism. This report describes an unusual primary cutaneous presentation of avian mycobacteriosis.
