Microscopic examination can show tumor cells with a characteristic abnormal elongated shape, called spindle cells.

镜检可看到典型的异常细长形状的肿瘤细胞，叫做梭形细胞。

And immunohistochemical staining of biopsy specimens can detect the presence of LANA-1 within the spindle cells and confirming the diagnosis.

活检样本的免疫组化染色可在梭形细胞中检测到LANA-1，从而确认诊断。

Diagnosis is made with biopsy of lesions and microscopic examination which can detect spindle cells and also with immunohistochemical staining which detect the presence of LANA-1.

可通过病灶组织活检，镜检发现梭形细胞以及免疫组化染色检测出LANA-1进行确诊。

There are mirror neurons; there are spindle cells (also called von Economo neurons) which play a role in the expression of empathy and the processing of social information.
