Plain-English summary
A 3-year-old male Bichon Frise was brought to the vet because he was feeling very tired, not eating, and had blood in his urine. An ultrasound showed a small, irregular mass in his bladder. After further tests, the vet diagnosed it as a paraganglioma, a type of tumor. The treatment plan would typically involve surgery to remove the tumor, but the specific outcome isn't mentioned. If your dog shows similar symptoms, it's important to consult your veterinarian for a thorough examination.

Abstract
A 3-year-old male Bichon Frise developed lethargy, anorexia and haematuria. B-scan ultrasonography examination revealed a small, irregular, soft-textured mass in the bladder. Histopathologically, there was an incomplete fibrous pseudocapsule around the tumour tissue and although there was clear demarcation from the surrounding tissue, there was invasion of the capsule. Tumour cells proliferated in nests or cords of variable size, separated by fibrovascular tissue. The neoplastic cells were immunopositive for chromogranin A, synaptophysin and neuron-specific enolase, and electron microscopy revealed that they contained cytoplasmic secretory granules. On the basis of these findings, the tumour was diagnosed as a primary paraganglioma of the urinary bladder.
