Summary: | In cattle, abdominal tumors leading to partial or total intestinal obstruction are rare. Here, it is described the clinico-pathological findings of two cows with intestinal obstruction by neoplasms. A crossbred cow presented apathy, weight loss, constipation, enophthalmos, ruminal and intestinal hypomotility, and abdominal distension in the right ventral quadrant. Pathological examination revealed bilateral ovarian teratoma. The other case was a cow that in the past 2 years had several episodes of squamous cell carcinoma in the third eyelid and vulva. During the 6 days prior to investigation, clinical signs of constipation and tenesmus were noted. Nodular and friable masses were located in the vulva, right third eyelid and cranially to the right kidney that were identified as poorly differentiated metastatic carcinoma of the adrenal cortex. To our knowledge, these are probably the first reports of ovarian teratoma and adrenal carcinoma causing clinical signs of intestinal obstruction in cattle.
RESUMO: Em bovinos, tumores abdominais que levam à obstrução intestinal parcial ou total são raros. Neste relato, descrevemos os achados clínico-patológicos de duas vacas com obstrução intestinal por neoplasias. Uma vaca mestiça apresentava apatia, perda de peso, constipação, enoftalmia, hipomotilidade ruminal e intestinal e distensão abdominal no quadrante ventral direito. O exame patológico revelou teratoma ovariano bilateral. O outro caso foi uma vaca que, nos últimos 2 anos, teve episódios de carcinoma de células escamosas na terceira pálpebra e vulva. Durante 6 dias antes da investigação, foram observados constipação e tenesmo. Massas nodulares e friáveis foram localizados na vulva, terceira pálpebra direita e cranial ao rim direito, que foram identificadas como carcinoma metastático pouco diferenciado do córtex adrenal. Ao nosso conhecimento, estes são os primeiros relatos de teratoma ovariano e carcinoma adrenal causando sinais clínicos de obstrução intestinal em bovinos. |
