Cytomorphology of Transmissible Venereal Tumors in Male and Female Non-descript Dogs: A Case Report

Abstract

Transmissible venereal tumors are among the most common skin tumors in dogs, frequently encountered in clinical practice. It is mainly transmitted through coitus and most commonly occurs in young, sexually mature dogs. Two dogs, a 7-year-old non-descript male and a 2-year-old non-descript female dog, were presented to the Department of Veterinary Gynaecology, Institute of Veterinary Sciences and Animal Husbandry, SOA (DU), Bhubaneswar, with a history of cauliflower-like growth in the prepuce of the male dog and vagina in the female dog. Fine needle aspiration biopsy (FNAB) was performed, and a Giemsa-stained smear was examined. Cytological examination revealed typical round- to slightly polyhedral-shaped cells with the presence of distinct, clear cytoplasmic vacuoles, often referred to as punctuate vacuolation, along with the presence of numerous neutrophils. Based on the cytological diagnosis, appropriate therapeutic management was initiated, and both cases responded well.
