A prospective study was conducted on twenty five cutaneous growths from various breeds of cattle were assessed for cellular proliferation by employing AgNORs (Argyrophilic Nucleolar Organizing Regions) staining method. Histochemical assessment of AgNORs revealed a significantly higher count in malignant neoplasms in comparison to benign neoplasms. The AgNOR counts in cutaneous and teat papillomas ranged from 1.98 to 2.68 with an average count of 2.33. The NOR counts was highest in squamous cell carcinoma (6.12), followed by melanoma (3.24), fibroma (3.16) and trichoepithelioma (2.31).
