OBJECTIVE: To review the experience with the diagnosis and treatment of @entity5 . METHODS: Between 1986 and 1996, 7 @entity1 with @entity5 were analysed. RESULTS: Compared with benign @entity1911 of @entity10163 , the malignant one usually exceeded 7.0 cm in diameter, irregular in shape, invading the surrounding tissue and the normal structure of the effected @entity10163 disappeared. Bleeding and @entity39 area were seen in @entity5 mass, even seemed as a @entity5409 with thick wall. In some @entity1 , blood @entity2922 and urine VMA significantly elevated without @entity101 . The separating phenomenon and progressive @entity353 , accelerated ESR were characteristics of @entity5 . CONCLUSIONS: In some @entity1 with @entity5 , histological findings are not consistent with their biological behaviors. Follow-up studies is mandatory in @entity5 as well as in benign one. Recurrence and/or @entity3 after operation often occur in @entity1 with @entity5 . In addition to early diagnosis and surgery, radiotherapy of @entity5 bed and systematic chemotherapy should be emphasized.
