Hematruia tumors, aswell as mesenchymal tumors have been described, beside the strange capacity hematurua induce different neoplasms in a same animal Tokarnia et al. We also preferred to use the term transitional or squamous carcinoma with areas of pseudo-glandular differentiation to the one of carcinoma of transitional cells with lumen similar to the gland, used by AFIP Murphy et al.

At the same time, previously described lesions have been reclassified adopting the more complete nomenclature currently used in human medicine. Most of nezootica received fragments were collected at enzooticx from several parts of the bladder, mainly from areas that presented macroscopic alterations; therefore areas of the bladder without evident macroscopic lesions, but with possible significant microscopic alterations, were excluded from this study.

Gabriel I ; Glaucia D. The changes found in the bladder of the animals were divided into neoplastic and non-neoplastic; the last ones were subdivided into inflammatory, hyperplastic and metaplastic.

The relationship between EMS and RS, physicochemical test and complementary chemical tests were evaluated.

Non-regenerative anemia was detected in How can we help you? The elucidation of the cause s of this “barrier against metastases” and their relationship with the chemical carcinogenesis induced by the ptaquiloside may be of interest in future studies that aim to combat cancer in man and animals.

Therefore these findings do not allow a simple correlation between this type of inflammation and some metaplastic or specific neoplastic alterations or with a specific protective alteration against tecidual infiltration of the neoplasia or metastases. Tumors of the urinary system, p.
