The clinical signs and histopathological features of a primary extragenital canine transmissible venereal tumour (TVT) are described in a 5 months old spayed male spitz dog subcutaneous 4×2.7 cm oval shape alopecic nodule was located on the caudoventral region of the right flank. The prefemoral and inguinal lymph nodes were not involved (FNA procedure). Cytologically, tumour cells were intermediate in size with a moderate amount of cytoplasm, and the nuclei were immature with finely reticular chromatin. The nucleus to cytoplasmic ratio was large. The cytoplasm was lightly to heavily basophilic and contained distinct small vacuoles at the periphery. On the basis of these characteristics, a diagnosis of TVT was made and confirmed by histological investigations. The skin bump was surgically excised and in his annual check up there were no skin bump or other forms of TVT.
