Granulosa cell tumours are uncommon ovarian tumours in the bitch and are rare in speyed bitches. This case report describes two cases of granulosa cell tumour in bitches that were speyed at less than 1-year-of-age. Both animals presented with persistent vulval bleeding. Although the majority of granulosa cell tumours are large enough to be palpated by the time of presentation, both tumours were relatively small. Granulosa cell tumour is a possible complication of incomplete ovarian excision at the time of ovariohysterectomy. In cases of granulosa cell tumour in previously speyed bitches, with no evidence of metastases, tumour resection should be curative. Ovaries should be double-checked at the initial ovariohysterectomy to ensure all normal ovarian tissue has been excised.

Medical records for 79 dogs with confirmed splenic hemangiosarcoma (HSA) following splenectomy were reviewed for information regarding either the presence or absence of macroscopic liver lesions and the histopathological characteristics of the liver. Only 29 of 58 dogs (50%) with grossly abnormal livers had HSA metastasis. No dogs with grossly normal livers had metastasis detected on liver pathology. Gross lesions in the liver such as multiple nodules, dark-colored nodules, and active bleeding nodules were highly associated with malignancy. For the dogs in this study, performing biopsy in a grossly normal liver was a low-yield procedure in dogs with splenic HSA.

The prognosis for ulnar osteosarcoma in this population was no worse and may have been better than the prognosis for dogs with osteosarcoma involving other appendicular sites. Partial ulnar ostectomy was associated with a low complication rate and good to excellent function and did not compromise survival time. Telangiectatic or telangiectatic-mixed histologic subtype was a negative prognostic factor for survival time. The efficacy of chemotherapy requires further evaluation.

Case summaryA 10-month-old domestic shorthair cat was evaluated for severe esophagitis and protracted vomiting and regurgitation secondary to a sliding (type I) hiatal hernia. The hernia and concurrent upper airway obstruction (nasopharyngeal polyp) were diagnosed with a multi-modality approach, including thoracic and abdominal radiographs, abdominal ultrasound, computed tomography and endoscopy. Following unsuccessful attempts at medical management, lower esophageal incompetence was successfully treated by employing a combination of surgical techniques, including herniorrhaphy, esophagopexy and modified (floppy) Nissen fundoplication.Relevance and novel informationA multi-modality imaging approach was valuable in completely assessing the extent of this cat’s disease. Although an untraditional approach, the authors report herein the first clinical description of the use of combined surgical techniques with the floppy Nissen fundoplication technique (an antireflux procedure) in a cat. This procedure was used as a first-line surgical technique in this cat with severe lower esophageal incompetence, and may be a viable option for cases non-responsive to other therapeutic interventions. Further investigation of this surgical technique is warranted.
