ABSTRACT
Background:
Cutaneous mycobacterioses show a worldwide distribution and manifest as three forms atypical mycobacteriosis, feline leprosy and cutaneous tuberculosis. Atypical cutaneous mycobacteriosis in cats is a rare disease commonly caused by fast-growing mycobacteria belonging group IV of the Runyon classification. This report describes for the first time an autochthonous case of atypical cutaneous mycobacteriosis in a cat from the municipality of Rio de Janeiro. Case A castrated female mongrel cat presented multiple ulcerated, exudative and alopecic lesions in different regions of the body. After sedation of the animal with 1% acepromazine hydrochloride (0.1 mg/kg) and 10% ketamine hydrochloride (10 mg/kg), clinical examination was performed and an exudate was collected from the ulcerated skin lesion for cytopathological analysis and mycological culture. The slide containing the lesion impression was stained by a rapid panoptic method. For fungal culture, material was collected with a sterile swab, seeded onto Sabouraud dextrose agar containing chloramphenicol and mycobiotic agar, and incubated at 25ºC. After antisepsis and asepsis, local anesthesia was performed with 2% lidocaine hydrochloride without vasoconstrictor and a 4 mm punch biopsy was collected from the lesion, fixed in 10% buffered formalin and sent for histopathological analysis. No fungal structures were detected by cytopathological or mycological analysis. Histopathological examination revealed ulcerated skin and the presence of a marked and diffuse pyogranulomatous infiltrate in the superficial and deep dermis, which also involving the subcutaneous tissue and underlying muscle tissue. Grocotts or PAS staining did not identify fungal structures. The Wade method was positive for acid-fast bacteria suggestive of Mycobacterium. Analysis of the hematological and biochemical profiles revealed no noteworthy alterations.(...)(AU)Palavras-chave
