Plain-English summary
An 11-year-old male Labrador retriever was brought in because he was having trouble urinating, a condition known as oliguria. An ultrasound showed a mass in his urinary bladder, so the veterinarian performed surgery to remove it. The mass was identified as a ganglioneuroma, a type of tumor made up of nerve cells. After the surgery, the dog was able to urinate normally again, indicating a successful outcome.

Abstract
An 11-year-old male Labrador retriever presented with chronic oliguria. Ultrasonography findings revealed a protruding mass at the neck of the urinary bladder. A cystotomy was performed, and the mass was removed by ligation with surgical sutures. Histopathological examination revealed conspicuous foci with a variable number of ganglion cells in the tumor and abundant interwoven bundles of schwannian cells with fine fibers. The ganglion cells were positive for neuron-specific enolase and neurofilament. The schwannian cells were positive for vimentin, S-100 protein, and glial fibrillary acidic protein. Thus, according to the classification of tumor with neuronal cell differentiation, the urinary tumor was diagnosed as a ganglioneuroma.
