The Tooth

In this in case that, the histopatolgico examination of the tumoral mass disclosed to proliferation of round cells the fusiformes with relation nucleus-cytoplasm 1/1, contends eosinoflico cytoplasm and little delimited, round, vesiculoso and central nucleus, I contend one the two nuclolos. Cells I contend up to three nuclei had been observed and figures of mitose were gifts in the ratio of one for field of 40X. The cells organized in whirlwinds composites for interlaced and not delimited beams of cells. Studies retrospective epidemiologists who take in account the tumors diagnosised in dogs, demonstrate that the incidence of this neoplasma varies of 1,3% the 1.5% (10,11). Amongst neoplasmas you pray, fibrossarcoma represents 11.11% of the diagnosised cases (5). However, exactly being less common the extra-verbal localizations for this neoplasma, the tooth of this clinical case presented the tumoral mass in the member previous right, in the region of the olecrano, being this important data for the establishment of distinguishing disgnostic futures of other patologias that attend a course with increase of volume of this region (osteossarcomas, condrossarcomas, higroma). The advanced age, the invasion and the tumoral return are compatible with what he was described for other authors (1,2,3,4,5).

However, in the gift in case that the animal presented metstase tumoral in linfonodo regional, what he is rare in animals with fibrossarcoma isolated (1,3). However this type of metstase was cited also by other authors (6). Studies tell that it does not have tumorais returns exactly after passed months of the amputation (with ample surgical edge) and that this neoplasma does not invade the fabric sseo (2). is often quoted as being for or against this. In the clinical case presented, exactly after 8 months of the last surgical procedure the patient meets without return signals or metstase and during the macrocospic examination of the amputated member was evident that the sseas structures were preserved. CONCLUSION Being based on the findings of this study, we conclude that it is possible to treat surgically, since that respected the surgical edges, fibrossarcomas little differentiated, making possible the complete recovery of the patient.
