Plain-English summary
A 10-year-old male Shih Tzu was brought to the vet because he was urinating blood. Tests showed a mass in his bladder, and after surgery to remove part of the bladder, it was found to be a rare type of cancer called leiomyosarcoma. Fortunately, the dog has been doing well for 29 months after the surgery, with no signs of the cancer returning or spreading. This case highlights the importance of checking for bladder masses and getting a proper diagnosis to guide treatment.

Abstract
A 10-year-old intact male Shih Tzu dog presented with hematuria. Double-contrast cystography revealed a polypoid filling defect at the apex of the urinary bladder. Ultrasonography revealed a heterogeneously hypoechoic intramural mass with minimal vascular flow beneath the submucosal layer. After partial cystectomy, a well-demarcated bladder leiomyosarcoma was diagnosed on histopathology. The patient was alive and well without any clinical signs, recurrence, or metastasis at the 29-month follow-up after the surgical removal of the bladder mass. Leiomyosarcoma should be considered as a differential diagnosis if mass-like lesions are observed in the urinary bladder, although this type of malignancy is rare in canines. Histopathological confirmation is important for predicting prognosis and determining further medical plans.
