恶性畸胎瘤:胚胎癌、也可见畸胎瘤肿块


更大的睾丸肿瘤,主要由胚胎癌组成,但散在质硬的白色区域在组织学上是畸胎瘤。因此,这个睾丸肿瘤是胚胎癌和畸胎瘤的混合体(往往叫做恶性畸胎瘤)。胚胎癌比精原细胞瘤侵袭性更强。AFP(甲胎蛋白)通常升高。
Here is an even larger testicular neoplasm. It is composed mostly of embryonal carcinoma, but there are scattered firmer white areas that histologically are teratoma. Thus, this testicular neoplasm is mixed embryonal carcinoma plus teratoma (sometimes called teratocarcinoma). Embryonal carcinoma is more aggressive than seminoma. The alpha- fetoprotein is often elevated.
