上皮性囊肿Cyst Epithelial · 卵巢 · 雌性生殖系统 · NTP ntp-0506
诊断要点：卵巢上皮性囊肿应当被诊断，但作为背景病变发生的囊肿无需分级。对于上皮性囊肿，诊断应包含囊肿类型作为修饰词（即，Ovary - Cyst, Epithelial）。
病变描述
上皮性囊肿（Epithelial cyst）（Figure 1、Figure 2）在小鼠中偶尔可见，在大鼠中罕见。这些囊肿被认为起源于卵巢表面上皮向下生长。囊肿内衬扁平、立方、柱状或鳞状上皮；鳞状上皮可能发生角化。内衬上皮可能与表面上皮相似。
诊断与分级建议（NTP 共识）
卵巢上皮性囊肿应当被诊断，但作为背景病变发生的囊肿无需分级。对于上皮性囊肿，诊断应包含囊肿类型作为修饰词（即，Ovary - Cyst, Epithelial）。如果认为囊肿与受试物相关，可对其进行分级以充分表征处理效应。如适用，诊断中可包含“双侧（bilateral）”和“multiple”这两个术语。

Comment：
Epithelial cysts ( Figure 1 and Figure 2 ) are seen occasionally in mice and are rarely seen in rats. These cysts are considered to arise from downgrowth of the surface epithelium of the ovary. The cysts are lined by flattened, cuboidal, columnar, or squamous epithelium; squamous epithelium may be keratinized. The lining epithelium may resemble that of the surface epithelium.
Recommendation：
Ovarian epithelial cysts should be diagnosed, but cysts occurring as background lesions need not be graded. In the case of an epithelial cyst, the diagnosis should include the type of cyst as a modifier (i.e., Ovary - Cyst, Epithelial). If the cysts are thought to be treatment related, they may be graded to fully characterize the treatment effect. If applicable, the terms "bilateral" and "multiple" may be included in the diagnosis.
