A canine mast cell tumor (MCT) is a common type of skin cancer in dogs that arises from mast cells, which are part of the immune system and play a role in allergic responses. These tumors can vary widely in appearance, from small, benign-looking lumps to large, ulcerated masses. They most frequently occur on the skin, but can also be found in internal organs. Diagnosis of canine mast cell tumors (MCTs) involves both identifying the tumor and determining its grade and potential to spread. The primary aim of the current study is to identify, incidence, occurrence and grading mast cell tumors of clinical samples submitted to Dept. of Veterinary Pathology. Veterinary College, Bengaluru. This study demonstrated relationship between Patnaik and Kiupel grading system and phenotypic traits, age and location of canine MCTs confirming the complex biological nature of this tumour.
