Ultrastructure of 10 adenolymphomas of parotid gland were studied. The neoplastic epithelium consists of "oncocytes" which are arranged in pseudostratified pattern. Their cytoplasm is almost totally packed with a large numbers of hypertrophic mitochondria showing a variety of peculiar forms. The amount and alteration of the mitochondria gradually increase in the order of pyramidal cell, common columnar cell and degenerated columnar cell. This might be a process of transposition representing degeneration due to metabolic disorder in the tumor. The obvious alterations of mitochondria are found in the cases with not only "hot" nodule but also "cold" nodule shown in the studies of 99mTc scintigraphy. There seems no relationship between "hot" nodule and alteration of mitochondria.
对10例腮腺腺淋巴瘤的超微结构进行了研究。肿瘤上皮由呈假复层排列的“嗜酸性细胞”组成。其细胞质几乎完全充满了大量形态各异的肥大线粒体。线粒体的数量和改变按照锥体细胞、普通柱状细胞和变性柱状细胞的顺序逐渐增加。这可能是一个转位过程，代表肿瘤中代谢紊乱导致的变性。在99mTc闪烁扫描研究中显示不仅有“热”结节而且有“冷”结节的病例中发现了线粒体的明显改变。“热”结节与线粒体改变之间似乎没有关系。
