Plain-English summary
A 7-year-old female Labrador retriever was diagnosed with a rare type of kidney cancer called leiomyosarcoma after showing signs of illness. The tumor was found in her right kidney and was examined under a microscope, revealing abnormal cells that were densely packed and had unusual shapes. This type of cancer is not common in dogs, and the findings were confirmed through various tests. Unfortunately, the abstract does not provide information on the treatment or outcome for this dog.

Abstract
A leiomyosarcoma that occurred in the right kidney of a dog (7-year-old female Labrador retriever) was studied pathologically. On histological examination, tumour cells were spindle-shaped, the cell density was high, and complex fasciculated tumour cells showing longitudinal and transverse cross-sections were observed. Both ends of the nuclei were rounded, the nucleoli were clear and many images of nuclear division were observed. Immunohistochemically, tumour cells reacted intensely with anti-vimentin antibody and anti-actin smooth muscle antibody, and mildly with anti-desmin antibody. On electron microscopy, the nuclei of tumour cells were rounded at both ends and elongated elliptically, and a large number of microfibrils with focal density and dense patches were observed in the cytoplasm. This is a case report of a very rare leiomyosarcoma of the dog kidney.
