Canine transmissible venereal tumor also known as transmissible venereal tumor, contagious venereal tumor, transmissible lymphosarcoma, transmissible venereal sarcoma and infectious granuloma. This tumor commonly affects the external genitalia in dogs of both sexes but More incidences in females are occurring as compared to males. The clinical signs of the genital system include serosanguineous vaginal discharge, cutaneous discharge, protrusion of neoplastic lesions, intermittent or continuous skin lesions, swelling of the genital area, excessive licking of the genital region and pain. The tumor initially is small and its color varies from pink to red, subsequently transforming into a large, ulcerated and infected mass. Over time, the volume of the tumor increases and the lesions develop into fragile, hyperemic, bleeding, multilobular and cauliflower resembling masses. A Sarabi bitch, 18 months old, was referred to the hospital of faculty of Shahid Chamran University in Ahvaz, suffering from serosanguineous vaginal discharge for the past three months. During examinations, the size of the vagina was normal and the discharge was observed to be red in color. CBC and biochemistry tests indicated a decrease in red blood cells and hematocrit level, along with an increase in fibrinogen. In the vaginal cytology sample, red blood cells, large and small intermediate cells and TVT round cells were observed. After multiple assessments, a diagnosis of transmissible venereal tumor (TVT) was confirmed. However, due to the owner’s lack of follow up, treatment was not completed.
