A case of ovarian dysgerminoma is reported. Both histology and cytology showed cells with distinctive anisokaryosis and large, sometimes bizarre, nucleoli as the most striking feature. A lymphocytic infiltration was present. Electron microscopy showed large convoluted nucleoli, structures resembling so-called "annulated lamellae" and glycogen particles, features that are typical of a germ-cell tumor. The cytologic, histologic and ultrastructural investigations revealed a dysgerminoma; that diagnosis was not certain on the frozen sections.
报告了一例卵巢无性细胞瘤。组织学和细胞学检查均显示，细胞具有明显的核大小不等及大的、有时形态怪异的核仁，这是最显著的特征。存在淋巴细胞浸润。电子显微镜检查显示有大的卷曲核仁、类似所谓“环层板”的结构及糖原颗粒，这些特征是生殖细胞肿瘤的典型表现。细胞学、组织学及超微结构检查均显示为无性细胞瘤；在冰冻切片上诊断尚不明确。
