Results: The patient presented non-painful, non-pruritic ulcerated lesions, hyperkeratosis and alopecia of the rostral and pelvic limbs, accompanied by nasal discharge and sialorrhea. The animal was subjected to cytopathology, histology and radiography, in addition to biochemical and hematological tests, which were inconclusive.
