Abstract


A male Japanese spitz (3 years) was brought at Himalayan Animal Rescue Trust (HART), Pokhara with a complaint of swollen gums and loss of appetite. A lobulated tumorous mass was seen at the gingival region on physical examination. Diagnosis and treatment of condition detected in the dog was the major objective. Impression smear of tumor cell was prepared and was observed under oil immersion microscope (100x). Microscopic examination shows the presence of vacuolations within the cytoplasm and the condition was diagnosed to be CTVT. Chemotherapy was performed using the most effective cytostatic agents I.e. Vincristine sulphate (once a week, I/v). The chemotherapy was repeated for 3 doses till the tumor gets completely regressed. The condition was resolved after third session of chemotherapy. Myelosuppression and gastrointestinal effects like vomiting are the major complications of using vincristine.
