In a study on cytopathological analysis of samples submitted for tumour diagnosis, papilloma was diagnosed in 48 dogs, which accounted to an incidence of 0.85% of the total tumours diagnosed in dogs during the period. Breed, sex and age wise analysis revealed the highest incidence in non descript and Labrador retrievers, with a male predominance and peak occurrence in the 1–5 year age group. Cytologically, the smears showed individual to clustered neoplastic cells of polyhedral to hexagonal shape resembling normal squamous epithelial cells and characterized by pink to purple cytoplasm and round to oval nuclei which were consistent with papilloma. Histopathology demonstrated classic finger like papillary projections of hyperplastic squamous epithelium overlying a fibrovascular connective tissue core, pronounced spinous (prickle) cell layer hyperplasia and hyperkeratosis with round to oval, vesicular nuclei.
