多卵卵泡Follicle Polyovular · 卵巢 · 雌性生殖系统 · NTP ntp-0512
诊断要点:卵巢,卵泡 - 多卵母细胞(Ovary, Follicle - Polyovular)在出现时应予以诊断,但不必进行严重程度分级。
病变描述
单个卵泡可能彼此紧密相邻(Figure 1)。这些卵泡每一个都含有一个卵母细胞。多卵母细胞卵泡(polyovular follicle)由单个卵泡构成,内含两个卵母细胞,每个卵母细胞各有其自身的细胞核、透明带(zona pellucida)和颗粒细胞层(Figure 2)。多卵母细胞卵泡偶尔作为背景性发现可见,但在 NTP 的一项亚慢性研究中,其曾在小鼠中被记录为与处理相关的发现。
诊断与分级建议(NTP 共识)
卵巢,卵泡 - 多卵母细胞(Ovary, Follicle - Polyovular)在出现时应予以诊断,但不必进行严重程度分级。

Comment:
Individual follicles may be closely adjacent to each other ( Figure 1 ). Each of these follicles contains one oocyte. A polyovular follicle comprises a single follicle containing two oocytes, each with its own nucleus, zona pellucida, and layer of granulosa cells ( Figure 2 ). Polyovular follicles are occasionally seen as a background finding but have been recorded as a treatment-related finding in mice in one subchronic NTP study.
Recommendation:
Ovary, Follicle - Polyovular should be diagnosed when present, but severity grading is not necessary.
