We came across two young dogs without a history of laparotomy in which intra-abdominal membranous structures were found during ovariohysterectomy. The membranous structures made ovariohysterectomy difficult; greater omental hypoplasia was suspected. A similar condition has been reported in humans without a history of laparotomy; however, it has not been reported in veterinary medicine. It was unclear whether either or both membranous structures and suspicion of greater omental hypoplasia in this case were congenital or secondary. It is important to report such cases because similar cases are likely to exist potentially.

A 13-year-old casted male LaPerm cat was admitted to the Tokyo Animal Medical Center, because of continuous vomiting. Despite initial treatment with intravenous crystalloid fluid and maropitant, the clinical condition of the cat did not improve. Abdominal ultrasonography revealed a hyperechoic nodule in the left pancreatic lobe. In addition, fasting serum gastrin levels were indicative of hypergastrinemia. These findings led to the clinical diagnosis of pancreatic gastrinoma. After diagnosis, a proton pump inhibitor was administered and a left-sided pancreatectomy was performed. At the time of the last follow-up, the clinical signs were well controlled for three years. To the best of our knowledge, this is the first case report of successful curable resection of feline pancreatic gastrinoma with a clinical diagnosis using ultrasonography and fasting serum gastrin evaluation.

An 11-year-old female cat weighing 3.3 kg presented with hemorrhages from a small nodule on the free edge of the left third eyelid. As the nodule had rapidly expanded and was suspected as a malignant tumor, it was removed surgically 60 days later using a semiconductor laser scalpel. The nodule, oval in shape, was 9 mm in length and 4 mm in maximum width. Histopathologically, the nodule was diagnosed as squamous cell carcinoma. Postoperatively, toceranib was administered orally every other day from day 16 to day 76 and β-glucan was administered daily since the early stage of the presentation until day 161. The cat remained in good condition and tumor-free on postoperative day 578.
