Plain-English summary
A group of Boxer dogs in Brazil developed skin problems known as canine leproid granuloma, which showed up as bumps, plaques, and sometimes ulcers, mainly on their ears. The diagnosis was confirmed through skin samples that revealed the presence of certain bacteria. While the exact cause was linked to a new type of mycobacterium, the study found no clear connection between the amount of bacteria and the severity of the skin lesions. Treatment details weren't specified, but understanding the condition can help veterinarians provide better care for affected dogs.

Abstract
Thirty-eight cases of canine leproid granuloma were diagnosed between 2000 and 2008. Diagnosis was based upon clinical and histopathological findings and the presence of acid-fast bacilli in skin sections. The clinical lesions were localized predominantly on the pinnae and included papules, plaques and nodules, with or without ulceration. Boxer dogs were the breed most affected. Histopathological findings included nodular to diffuse pyogranulomatous, lymphoplasmocytic inflammatory infiltrates, with or without necrosis, localized in the dermis or subcutaneous tissue. The bacillary loading and morphology were variable among the lesions analysed. There was no significant correlation between bacterial load and histopathological pattern, dominant type of inflammatory infiltration or the amount of necrosis or giant cells. No correlation was observed between giant cells and histopathological pattern. In the majority of cases where a PCR-based assay was done, a novel mycobacterium species as the main aetiological agent was identified, as reported in previous studies.
