Abstract

The study was aimed at diagnosing transmissible venereal tumour (TVT) initially using cytological techniques and later the results were compared with routine histopathology. Two Spitz and one Labrador bitches with tumour masses of about 4-7.5 cm in diameter seen on the vagina and vulva were used as material for the study. Fine needle aspiration cytology (FNAC) with various cytological stains and routine histopathology with haematoxylin and eosin (H&E) staining were performed. Grossly, the tumour masses appeared irregular, cauliflower like and had a tendency to bleed. Cytologically, the tumour yielded a homogenous, sheet-like high cellular mass. Cytoplasm with punctate vacuoles, anisokaryosis with anisonucleoliosis and coarse to reticulate nuclear chromatin were prominent features. Histopathology showed sheets of round cells with nuclear and cytoplasmic variations. The study concluded that cytology could be used as a quick, rapid, field diagnostic technique in combination with histopathology for the diagnosis of TVTs.
