Plain-English summary
A 10-year-old male Beagle was brought to the vet after experiencing two months of intermittent vomiting and abdominal pain. Imaging tests suggested a splenic tumor, but during surgery, the vet found a large mass on the greater omentum (a fold of tissue in the abdomen) along with fluid buildup. The mass was diagnosed as leiomyosarcoma, a type of cancer, after examining the tissue. The dog underwent surgery to remove the tumor, which is a significant step in treating this condition.

Abstract
A 10-year-old castrated male Beagle dog was presented with a 2-month history of intermittent vomiting and abdominal pain. The dog was referred to the Veterinary Teaching Hospital at Iwate University for further evaluation, and a splenic tumour was suspected on the basis of ultrasonography and computed tomography. Surgery identified a large, solid, light-pink mass on the greater omentum with blood-coloured ascites in the abdominal cavity, and resection was performed. Microscopically, the mass comprised spindle-shaped tumour cells and scattered osteoclast-like giant cells. Most spindle-shaped cells were positive for vimentin, desmin, and smooth muscle actin (α-SMA), whereas osteoclast-like giant cells were positive only for vimentin. On the basis of histopathological and immunohistochemical findings, a diagnosis of leiomyosarcoma was made. To the best of our knowledge, this represents the first report of leiomyosarcoma associated with osteoclast-like giant cells developing from the greater omentum in a dog.
