Cytological Diagnosis and Treatment of Transmissible Veneral Tumor in Dog- A Case Study

Abstract

Canine transmissible venereal tumor (CTVT), also known as canine transmissible venereal sarcoma (CTVS), stickers sarcoma and infectious sarcoma is a benign reticuloendothelial tumor of the both male as well as female dog that mainly affects the external genitalia. This tumor was found in male 4 years old Labrador dog. Anamnestic data revealed normal body vitals including temperature of 102oC and pulse of 80/minute, except spontaneous bleeding from prepuce and the presence of serosanguinous bloody discharge in the urine since last 6 months. Upon clinical examination, a multilobular typical cauliflower shaped tumerous mass was located on the base of the penile bulb, which actually caused sanguinous discharge. The sample material for cytological diagnostics were taken with the help of impression method and three cytological impression smears were prepared and stained with wrights Giemsa for diagnostic purpose. Results were suggestive of presence of high cellularity, presence of tumor cells which were large round cells with round nucleus, coarse and reticulated chromatin, abundant and lightly basophilic cytoplasm and multiple punctate cytoplasmic vacuoles, all conclusive of the cytological diagnosis of CTVT. After surgical resuction of the mass, medicinal therapy was started by vincrystine sulphate @0.025mg/kg BW along with Rantidine, Avil and multivitamin on weekly basis.
