左心室肥大

左心室肥大

图示:左心室肥大
并不是所有的组织体积增大的病变都属于肿瘤。为了适应高血压时过重的压力负荷左心室发生了这种变化。心肌纤维数量没有增加,体积增大了,但结构正常。

Any increase in tissue size is not necessarily neoplasia. Here is an example of left ventricular cardiac hypertrophy in which there has been an increase in the size of the myocardial fibers in response to an increased pressure load from hypertension. With hypertrophy, the cells increase in size, but the cells do not increase in number. Except for being larger, the cells are normal in appearance.
