Abstract: Canine melanoma is a malignant cancer that originates from melanocytes, the pigment-producing cells in dogs. This neoplasm manifests in various anatomical locations, such as the oral cavity, skin, digits, and mucocutaneous junctions. In this specific study, the identification of tumours involved the utilization of both cytological and histopathological techniques. Cytological assessments encompassed the use of Fine Needle Aspiration Cytology (FNAC) and impression smears, applied to both palpable and non-palpable tumour masses. Cytological smears revealed anisocytosis, anisokaryosis, and brownish-black intracytoplasmic pigments. Histopathology revealed densely packed spindle-shaped melanocytes and epithelial cells forming pigmented islands, accompanied by the presence of giant cells and mitotic figures. Canine melanoma poses a significant health threat, with diverse clinical presentations so timely diagnosis and treatment of melanoma is necessary.
