Tumor fibroso solitario. dos casos adicionales con implicaciones urológicas

Abstract

Solitary fibrous tumour is a well defined pathological entity originally described as a tumour of the pleura, but the occurrence of this neoplasm has increasingly been described at other sites. At present the development of these tumours is recognized as possible in virtually all anatomical sites. The rarity of this type of pathology has not allowed up to the present time clarification of the histogenesis, clinical behaviour, treatment and prognosis of these tumours. Differential diagnosis becomes important, especially in extra-thoracic sites so as not to mistake them for much more aggressive mesenquimal tumours. Two additional cases of this neoplasm are presented, one of them responsible for obstructive uropathy, accidentally found in a patient suffering renal trauma. The second tumour was located in the spermatic cord. A review of the theme is presented based on the available literature.

Tumor fibroso solitario extrapleural de localización inusual

“…El TFSE es un tumor mesenquimal infrecuente, incluido dentro de los sarcomas de partes blandas. Se presenta en adultos de mediana edad, sin diferencias significativas respecto al sexo 3 . Su presentación clínica es inespecífica y en la mayoría de los casos secundaria al efecto de masa del tumor.…”

“…La mayor parte de los TFSE se comportan de modo benigno, aunque en la actualidad se prefiere considerarlos como de comportamiento clínico incierto, ya que un porcentaje variable, entre el 13% y el 23%, han demostrado ciertas características de agresividad debido a su efecto de masa o por metástasis a distancia. El pronóstico es imprevisible, ya que el TFSE puede recurrir o metastatizar, incluso en ausencia de criterios de malignidad 3 .…”
