The fine structure of the stomal component of cystosarcoma phyllodes was compared with that of intracanalicular fibroademona, leiomyoma and leiomyosarcoma. The stromal cells of fibroadenoma was intermediate between fibroblasts and smooth muscle cells and may be designated as myofibroblasts. The stromal cells of cystosarcoma phyllodes have fulfilled the ultrastructural criteria for smooth muscle cells. Therefore, cystosarcoma phyllodes should be regarded as smooth muscle tumors or those of myoepithelial origin.
将叶状囊肉瘤的间质成分的精细结构与管内纤维腺瘤、平滑肌瘤及平滑肌肉瘤的精细结构进行了比较。纤维腺瘤的间质细胞介于成纤维细胞和平滑肌细胞之间,可称为肌成纤维细胞。叶状囊肉瘤的间质细胞符合平滑肌细胞的超微结构标准。因此,叶状囊肉瘤应被视为平滑肌肿瘤或肌上皮起源的肿瘤。
