I would add some immunohistochemical stains to further investigate the nature of the malignant cells present: Cam5.2 and Ck7 to rule out metastatic carcinoma; S100, Melan A and HMB45 to rule out metastatic melanoma. I would also like to see some photos of positive GFAP stain. This challenging case is not straight forward as I thought.

There is necrosis and cytologic atypia in more cellular areas in this neoplasm, consistent with malignancy. 该肿瘤在细胞丰富的区域有坏死和非典型性，应该是一恶性肿瘤。Some cells have clear cytoplasm, while others are in solif nests. 有些细胞的胞浆透明，另一些细胞呈实性细胞巢。I would consider this as a metastatic carcinoma, and possible primary origins include lung and kidney. 我考虑可能是转移性癌，可能原发于肺或肾。
