Diagnostic and Surgico-therapeutic Management of Perineal Tumour in Dogs

The benign perianal tumour form comprises more than 80% and is third most common tumour in male dogs. The present study was planned to record the cases of perineal tumour, their diagnosis and management. Their age, sex, breed, size of tumour and clinical history were recorded. Clinical, physical, radiographic and ultrasonographic examination of affected dogs were also done accordingly.

In uncastrated male dogs first castration was done 2-4 weeks before excision of tumour via open prescrotal castration method. Corrective surgery was performed for tumour excision in 9 dogs under general anaesthesia as per the standard technique. Two dogs diagnosed with venereal granuloma, were treated by using the chemotherapeutic protocol.

During the study of perineal affection, 11 cases of perineal tumour were recorded in intact male dogs. Indian Spitz breed was most commonly affected followed by other breeds. Varying size of perineal tumours were recorded along with anorexia, faecal and urinary incontinence. Radiographic examination and Ultrasonography were also done to determine the nature and extent of perineal swelling for accurate removable of growth without any complications.

In the haematological studies, there was significant decrease in neutrophil and increase in lymphocyte and monocyte count. Biochemical parameters indicated a non-significant decline. In cytological and histopathological analysis, it was confirmed that 5 dogs had perianal adenoma, 2 had perianal epithelioma, 2 had venereal granuloma, 1 had anal gland adenoma and 1 had adenocarcinoma. Perianal adenoma could be managed successfully by surgical excision with castration. Venereal granuloma growth in perineal region could be corrected successfully with chemotherapeutic protocol with good outcome.
