## 一句话结论
卵巢旁囊肿（paraovarian cysts）很可能起源于中肾管（mesonephric ducts）和副中肾管（paramesonephric ducts）的退化残余。

## 病变描述（中文）
卵巢旁囊肿（paraovarian cysts）很可能起源于中肾管（mesonephric ducts）和副中肾管（paramesonephric ducts）的退化残余。卵巢旁囊肿与卵巢不相连；它们位于卵巢邻近的卵巢系膜（mesovarium）或输卵管系膜（mesosalpinx）内（Figure 1、Figure 2、Figure 3、Figure 4）。卵巢旁囊肿由扁平、立方或柱状上皮衬覆，上皮可具有纤毛。可见囊肿与卵巢系膜内的卵巢旁结构相连。囊壁内是否存在平滑肌不定。

## 诊断与分级建议（NTP 共识，中文）
卵巢旁囊肿应予以诊断，但作为背景性病变发生的囊肿无需分级。对于卵巢旁囊肿，诊断应包含囊肿类型/部位作为修饰词（即 Ovary, Paraovarian tissue - Cyst）。如果认为囊肿与处理相关，可对其进行分级以充分描述处理效应。如适用，诊断中可包含“双侧（bilateral）”和“multiple”这两个术语。

## 英文原文 · Comment
Paraovarian cysts likely arise from vestigial remnants of the mesonephric and paramesonephric ducts. Paraovarian cysts are not connected to the ovary; they are adjacent to the ovary in the mesovarium or mesosalpinx ( Figure 1 , Figure 2 , Figure 3 and Figure 4 ). Paraovarian cysts are lined by flattened, cuboidal or columnar epithelium, and the epithelium may be ciliated. A connection to paraovarian structures in the mesovarium may be seen. The presence of smooth muscle in the wall of the cyst is variable.

## 英文原文 · Recommendation
Paraovarian cysts should be diagnosed, but cysts occurring as background lesions need not be graded. In the case of paraovarian cysts, the diagnosis should include the type of cyst/location as a modifier (i.e., Ovary, Paraovarian tissue - Cyst). 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.
