Mixed mammary gland tumors are the most frequent canine mammary gland neoplasms with a high incidence rate among females, however, there is paucity of studies that describe their clinic-pathological presentations and management approaches. This case evaluated the clinic-pathological data and management of mixed mammary gland tumors. A 10-year-old Lhasa Apso bitch weighing 11.4kg was referred to the University of Jos Veterinary Teaching Hospital with a ventral abdominal mass. Clinical examination revealed an enlarged left inguinal mammary gland with two palpable masses. The inguinal region was aseptically prepared for surgery and anesthesia achieved by the administration of 1% atropine sulphate (Atropine® - Shanxi Shuguang Pharmaceutical Co., Ltd., Qixian, China) and Chlorpromazine as preanesthetics and 50mg/mL Ketamine hydrochloride (Jawa ketamine® - Swiss Parenterals Ltd, Gujarat, India) + 2% Xylazine (Alfasan, Woerden-Holland) as induction and maintenance anesthetics. The glandular, connective/fibrous and fatty tissues of the mammary gland were carefully dissected to achieve the complete excision of the encapsulated mammary tumour masses before the reconstruction of the resulting defect. Postoperatively, penicillin and streptomycin, piroxicam, vitamin B complex, dexamethasone, vincristine sulphate and ivermectin were administered. The excised masses histologically presented numerous tubules with some containing mucin. Also there were the presence of acini with neoplastic epithelial cells and myoepithelial cells, cartilage and bony trabeculae. Surgical debulking with adjunctive immuno-chemotherapy was curative for the mixed mammary gland tumours in this bitch.
