Abstract
The samples suspected for Transmissible Venereal Tumour (TVT) are regularly being received from
Teaching Veterinary Complex (TVC) to centralized clinical laboratory and Department of Veterinary pathology
for cytological and histopathological examination, respectively. A survey study of canine TVT was made from
the past five years from 2015 to 2019 based on cytology and histopathology data. Among the total number of
320 samples, 221 samples were from female and 99 samples were from male dogs. Though the occurrence was
recorded between 1 to 10 years, the higher incidence was recorded from 4 to 5 years followed by 3 to 4 years
of age. Breedwise incidence showed that the Non-Descriptive dogs are mostly affected with TVT followed by
Chippiparai and the lower incidence was recorded in Spitz. Cytological diagnosis is a rapid and simple field
diagnostic techniques for confirmation of TVT. The cytological picture exhibited sheets of discrete round to
polyhedral cells with coarse to reticulate chromatin, hyperchromatism, multiple nucleoli and mitotic figures.
These cells had basophilic cytoplasm with varied numbers of punctuate vacuoles. Histopathology of TVT
tissue sections showed sheets of round cells with vesicular nucleus, thin fibrovascular stroma and numerous
mitotic figures.
