Plain-English summary
A 14-year-old domestic shorthair cat was brought in for urinary incontinence and inappropriate elimination that had been happening for five months. An ultrasound showed a mass in the urinary bladder, which was surgically removed through a partial cystectomy. Tests confirmed that the mass was a malignant peripheral nerve sheath tumor, a rare type of cancer. The cat's condition was unusual as this type of tumor had not been previously reported in the bladder of cats or other pets.

Abstract
A 14-year-old domestic shorthair cat presented with a 5-month history of urinary incontinence and inappro-priate elimination. Ultrasonography revealed a well-marginated, vascular mass of mixed echogenicity ex-tending from the dorsal wall of the urinary bladder into the lumen. Partial cystectomy was performed for re-moval of the urinary bladder mass; histopathological evaluation revealed a spindle cell neoplasm with a prominent palisading pattern. Histomorphologic features and immunohistochemical demonstration of vimentin, glial fibrillary acidic protein and S-100 protein, combined with negativity for smooth muscle actin and desmin were consistent with malignant peripheral nerve sheath tumour. This case report describes a novel location of malignant peripheral nerve sheath tumour; to the authors' knowledge, the bladder has not been described as a site of origin in the cat or any other domestic species.
