“…This is the first report of a primary ureteral giant cell tumor in a dog. Similar to previous cases of ureteral tumors, this dog was presented with clinical signs associated with ureteral obstruction causing hydroureter and hydronephrosis . There were a few cytologic criteria of malignancy, and histologic evaluation illustrated that the mesenchymal neoplasm was covered with transitional epithelium and had minimal association with local tissue, suggesting that the tumor was slow‐growing.…”

An 8-year-old male neutered Pomeranian dog was presented to the Veterinary Teaching Hospital at Oregon State University for surgical treatment of hydronephrosis of the left kidney and a left cranial abdominal mass. A primary ureteral mass was found during exploratory surgery, and the mass was resected and ureteral anastomosis was performed. Cytologic evaluation of the mass revealed 3 distinct cell populations, including a large number of multinucleated giant cells, a moderate number of thin spindle-shaped cells, and cohesive clusters of transitional epithelial cells. The cytologic diagnosis was giant cell sarcoma. The diagnosis was confirmed by histologic examination, and immunohistochemical staining was performed. The spindle-shaped cells and multinucleated giant cells were both immunoreactive for vimentin and spindle-shaped cells for S-100. Tumor cells did not express wide-spectrum cytokeratin, broad-spectrum muscle actin, smooth muscle actin, sarcomeric actin, desmin, BLA36, Mac 387, synaptophysin, neuron-specific enolase, glial fibrillary acid protein, or von Willebrand factor. These findings are most consistent with an anaplastic sarcoma with giant cells. This is the first case report of a primary ureteral giant cell sarcoma in a dog.

Pólipos em vesícula urinária de um cão - relato de caso

et al. 2011

Pólipos são formações benignas raramente encontradas no aparelho urinário tanto na medicina veterinária como na medicina humana. A etiologia ainda não foi identificada, mas acredita-se que ocorra por infecção recorrente do trato urinário, caracterizando uma doença chamada de cistite polipóide. Descreve-se no presente artigo um caso de pólipo vesical em cadela castrada Cocker Spaniel de 11 anos com histórico de hematúria há dois anos. Foi identificada infecção urinária por Serratia spp e ao exame ultrassonográfico observou-se duas massas pedunculadas irregulares em face cranioventral e espessamento da parede vesical. O animal foi submetido à cistectomia parcial para remoção das massas onde foram observadas várias outras pequenas formações próximas à mesma região. O exame histopatológico confirmou o diagnóstico de pólipos vesicais. Para o tratamento da doença, além da excisão cirúrgica, a infecção deve ser tratada adequadamente. O prognóstico é bom, porém casos de recidivas podem ocorrer especialmente quando a remoção é feita apenas a partir da mucosa vesical. Palavras-chave: Infecção do trato urinário, pólipo vesical, cães DOI: 10.5433/1679 Abstract Polyps are benign formations rarely found in the urinary tract both in veterinary medicine and human medicine. The etiology was not identified, but it is believed to occur by recurrent infection of the urinary tract, characterizing a disease called polypoid cystitis. It was described in this report a case found in a neutered 11 years-old bitch Cocker Spaniel with a history of hematúria for two years. It was identified a urinary infection by Serratia spp and the ultrassond examination showed two irregular pedunculated masses in the cranioventral portion and thickening of the bladder wall. The animal was underwent parcial cystectomy to remove the masses where it was observed other small formations near the same region; the material was referred to histopathological examination to confirm the diagnosis of bladder polyps. For treatment of disease, in addition to surgical excision, the infection should be treated properly. The prognosis is good, but cases of recurrence may occur especially when the removal is made only from the bladder mucosa.

“…Secondary ureteral involvement of bladder or renal tumours is more common. There are 17 reported cases of primary ureteral tumours, including leiomyoma, leiomyosarcoma, sarcoma, spindle cell sarcoma, giant cell sarcoma, mast cell tumour, transitional cell carcinoma, fibropapilloma and fibroepithelial polyp . The common presenting clinical signs include polyuria, polydipsia, pollakiuria, nocturia, haematuria, urinary incontinence and urinary tract infection .…”

However, in some of the reported cases the dog was presented only with clinical signs that were not suggestive of urinary tract disease, such as lethargy, exercise intolerance, pyrexia, anorexia, weight loss, abdominal pain and vomiting …”
