case_images: Tomographic images of a French bulldog dog with an intranasal transmissible venereal tumor. (A) Sagittal image of the bone philtrum, (B) transverse image of the soft tissue philtrum, and (C) dorsal image of the bone philtrum. Presence of increased volume of soft tissue inside the right nasal cavity in the ventral aspect in the caudal half (yellow arrows); the nasal turbinates are not delimited.

case_images: Measuring approximately 2.8 cm in length x 1.3 cm in height x 1.7 cm in width, where, at the site of this increase in volume, the nasal turbinates were not delimited, possibly due to bone lysis secondary to the injury and discrete fluid content inside the right nasal cavity, rostral to the increase in volume mentioned, with the main differential diagnosis being a neoplastic process (Figure 1).
case_images: A and B-Rhinoscopy of a French bulldog with an intranasal transmissible venereal tumor shows the presence of a neoformation in the right and left choanae region, with an irregular and friable appearance, soft consistency, and reddish-white color (white arrows).

case_images: During rhinoscopic examination, a neoformation was observed in the region of the right and left choanae, with an irregular and friable appearance, soft consistency, and reddish-white coloration; the region mucosa was redder than normal (Figure 2).
case_images: Transverse tomographic images of the bone filter of a French bulldog with an intranasal transmissible venereal tumor before (A) and after 6 weeks of treatment with a weekly application of vincristine sulfate (B). Presence of amorphous soft tissue content with poorly defined limits, with markedly smaller dimensions after treatment (B) (yellow arrows).

case_images: However, in markedly smaller dimensions, in a subjective evaluation, approximately 10% of the previously delimited content (Figure 3).
case_images: Rhinoscopy of a French bulldog with an intranasal transmissible venereal tumor after 6 weeks of treatment with a weekly application of vincristine sulfate. Rhinoscopic examination revealed a neoformation in the ventral region of the choanae, with an irregular and friable appearance, soft consistency, and reddish-white coloration (white arrow). The neoformation is considerably smaller than the examination before treatment.
