A three year old nulliparous Boerboel bitch presented with complaints of fever and inappetence six weeks after an elective caesarean section was diagnosed with an extrauterine foetus. A per-cutaneous abdominal ultrasound revealed a foetal sac showing a well-developed skeletal structure and the absence of foetal movement or heartbeat. During laparotomy, a foetal sac containing a dead foetus was located between the spleen and the stomach. The foetal sac was excised following ligation of its mesenteric attachment to the spleen. The previously operated uterus was observed to have involuted but revealed a small bud observed on the middle portion of the left uterine horn. The histological findings of the foetal sac revealed fibro-adipose tissue with numerous congested vessels. It was concluded that the Boerboel bitch had a secondary abdominal ectopic pregnancy and recommended that owing to the difficulty of diagnosing the condition before or during routine elective caesarean surgery, post-operative abdominal ultrasound would have been instructive.

A five-month-old female Boerboel puppy presented with a rapidly expanding fibrous growth around the canine tooth of the right maxilla was diagnosed as having acanthomatous ameloblastoma based on findings from skull radiography, cytology of fine needle aspiration, biopsy and histopathology of resected growth. Lateral radiograph of the skull revealed moderate osteolysis of the maxilla with presence ofun-erupted maxillary canine teeth. Cytology of fine needle aspirate from the growth showed clusters of epithelial cells that were  hyperchromatic and showing palisade arrangement. The mass was surgically resected using diathermy instrument following general anaesthesia using combination of intramuscular injection of xylazine (0.5mg/kg), and intravenous injection of propofol (4mg/kg). Post-operative management included Ibuprofen suspension (100mg) administered for 3-days, intravenous vincristine (0.5mg/m2 ) once weekly and oral cyclophosphamide (50mg) was administered twice weekly for six weeks. Histopathology of the growth showed odontogenic epithelium embedded in pulp ectomesenchyme. Features of odontogenic epithelium include palisading epithelium with anti-basilar nuclei and centrally located cells having features of stellate reticulum. This is probably the first reported case of acanthomatous ameloblastoma in a Boerboel puppy that was successfully managed.
