RESUMO

O tumorsolitário fibroso é uma neoplasia rara, derivada de células mesenquimatosas que necessita para o diagnóstico definitivo do recurso à análise imuno-histoquímica. A maioria destes tumores é benigna, sendo o tratamento de eleição, quer para as variantes benignas quer malignas, a ressecção cirúrgica completa. No entanto, por estarem descritas recidivas locais e/ou à distância, devem manter-se estes doentes sob vigilância apertada, sendo inadequado encarar estas lesões como definitivamente benignas. Os autores fazem uma breve revisão da clínica, características radiológicas, achados histológicos e opções terapêuticas e relatam dois casos clínicos, discutindo as diferenças entre eles.

ABSTRACT

Solitary fibrous tumor is a rare neoplasm derived from mesenchymal cell. To achieve a diagnosis and to differentiate from others neoplasm immunohistochemical analysis is needed. The majority of these tumours are benign, and complete surgical resection remains the mainstay of therapy for both the benign and malignant variants. However, there are cases of local and distant recurrences, so patients should have a close follow-up and it is far incorrect to look at this lesion as definitely benign. The authors review clinical presentation, radiological features, histological findings, and treatment options for this tumor and report two clinical cases discussing the differences between them.
