Background: Among the bacterial dermopathy the canine leproid granuloma (CLG) is a nodular pyogranulomatous disorder that affects the skin or subcutaneous tissue mainly in the dorsal face of ear pinna, head, and extremity of memberscaused by Mycobacterium spp. The pathogenicity is still not well clarified regarding the causative agent, which has notyet been completely typified, but phylogenetically, it is related to Mycobacterium tilburgii, M. simiae, and M. genavense,in Brazil, by the species M. murphy. The objective of this study is to report a case of canine leproid granuloma, throughcytology and histopathology, and present the therapeutic procedures until the regression of cutaneous lesion.Case: A 5-year-old Boxer breed, intac male weighing 32 kg, was assisted at the Veterinary Clinic of UNIFIMES, in MineirosCity, Mid-West Region of Brazil, GO, Brazil. The animal had 4 nodules in the ears with evolution of 30 days, with nopruritus and without previous treatment. During the physical exam, the animal had normal physiological parameters. Thecutaneous lesions were characterised by papules and alopecic nodules of firm to fibroelastic consistency, with progressiveincrease, located in the convex face of the ears. The fine needle aspiration puncture technique (FNAP) and histopathologyfor a definitive diagnosis was used, allowing the differentiation between inflammatory processes, infectious and neoplastic. Furthermore, blood was collected for hemogram and biochemical analysis for the assessment of renal and hepaticfunctions. In cytology, the stained blades by the Diff-quick stain in the microscopic exam had elevated cellularity, withseveral macrophages, and bacilliform structures in the negative image. Staining was also conducted....(AU)
