Perianal (Hepatoid) Gland Adenoma in Labrador Dog: Its Diagnosis and Surgical Management

Abstract

A six year old male Labrador dog weighing 45 Kg was presented with a complaint of external growth in perianal region reported from past one year of presentation to Teaching Veterinary Clinical Complex, MVC, Mumbai. Clinically dog showed haematochezia, constipation and tenesmus. Fine needle aspiration cytology of the perianal growth as well as the impression smear taken from growth when stained with Leishman stain showed oval to polygonal cells with round nucleus and abundant pink cytoplasm and indicated perianal gland adenoma. The growth was removed by surgical extirpation under general anaesthesia using xylazine (0.5 mg/Kg b. wt) and ketamine (5mg/ Kg b. wt) and maintained by diazepam (0.5 mg/kg b. wt.). Surgical intervention was carried out by incising the base of tumor and dissecting surrounding structures after ligation of blood vessels. Internal muscle layer and fascia was sutured by chromic cat gut No.0 by simple continuous pattern and externally cross mattress pattern with nylon. Post-operative management was carried out with Ceftriaxone (@ 15.25 mg/kg b. wt.) and meloxicam (0.2mg/kg b. wt. intramuscularly). The weight of growth was 150 grams and had dimensions of 6.5 cm by 4 cm. Histopathological examination confirmed hepatoid gland adenoma with features of round to oval cells with round nucleus and abundant cytoplasm with cells arranged in sheets surrounded by fibrous connective tissue. The, present communication reports a case of Hepatoid gland adenoma in male Labrador dog and its surgical management.
