XXXX : Is preoperative biopsy always mandatory?

@entity808 @entity1 @entity353 @entity548 @entity5 @entity425 @entity1142 @entity4847
INTRODUCTION: @entity808 is the term given to @entity5 arising from Schwann cells of any nerve @entity4847 . It may arise in the retroperitoneum, where it can attain enormous sizes and cause considerable diagnostic and therapeutic difficulties. A variety of incapacitating symptoms may arise, depending on its size alone and the related contagious organs. PRESENTATION OF CASE: A 71-year-old female, who was incapacitated by a giant abdominal mass, associated with @entity353 , immobility, general @entity425 and @entity1142 . Radiologically, the presence of a huge @entity5 was confirmed. A preoperative tissue diagnosis was entertained but omitted, and we resorted to direct surgical excision instead. During surgery, significant @entity548 from the surrounding lumbar vessels was encountered, but it was controlled and the @entity5 was excised intact. Histopathologically, it showed the histologic features of @entity808 . DISCUSSION: In the @entity1 presented here, who was rendered immobile by the @entity5 , total excision or at least debulking seemed appropriate, regardless of any biopsy result. CONCLUSION: The diagnosis of @entity808 and its variant " @entity808 " should be considered when a huge @entity5 is encountered. Although CT guided biopsy may be helpful in reaching a preoperative diagnosis, this might not change the decision for the need of total @entity5 excision or at least debulking, in the presence of incapacitating symptoms. With large @entity5 , the possibility of perioperative exanginating @entity548 should be remembered and the necessary precautions activated.
