A case of Rhabdomyosarcoma(Sarcoma botryoides) of Bladder in a Child
Sarcoma botryoides, which is a variant of embryonal type of rhabdomyosarcoma, is rare tumor. The embryonal rhabdomyosarcoma arise histogenetically from the tissue derived from the mesenchyme of the urogenital ridge. Grossly, they assume a lobulated or grapelike appearance whence comes the name "botryoid" sarcoma. We have recently experienced a case of sarcoma botryoides of the bladder and prostate in a 6-year-old toy who was admitted to Han Yang University Hospital on September 19, 1979. The bladder was filled with multiple, soft, polypoid, gray nodules. On section, the cut surface of the tumor mass has shown translucent and gelatinous appearance. Microscopically, the tumor mass has shown a loose textured area and compactness. The transitional epithelium on the bladder was intact and a cambium layer of Nicholson was present just beneath the mucous membrane. The neoplastic cells were spindled, oval and rarely multinucleated. No striation was found on the Phosphotungustic acid hematoxylin stain.
