## 一句话结论
鳞状上皮囊肿（Squamous epithelial cyst）（Figure 1、Figure 2）偶见于大鼠的子宫颈，较少见于阴道。

## 病变描述（中文）
鳞状上皮囊肿（Squamous epithelial cyst）（Figure 1、Figure 2）偶见于大鼠的子宫颈，较少见于阴道。它们类似于皮肤中所见的表皮囊肿，囊壁由复层鳞状上皮构成，中央腔内可含有角化物质及数量不等的炎性细胞。这些囊肿有时为双侧性。这些囊肿必须与局灶性（focal）坏死或脓肿相鉴别，后两者均无上皮衬覆。它们可能起源于遗迹结构。鳞状囊肿必须与子宫的鳞状化生相鉴别，后者见于远离子宫颈的子宫体部或子宫角内。

## 诊断与分级建议（NTP 共识，中文）
发生于子宫颈的鳞状囊肿应诊断为Uterus, Cervix - Cyst, Squamous（在NTP研究中，子宫颈被归类为子宫的一个亚部位）。囊肿无需分级，除非分级有助于表征处理效应。继发于囊肿的炎性改变不应单独诊断，除非其严重程度足以支持单独诊断。

## 英文原文 · Comment
Squamous epithelial cysts ( Figure 1 and Figure 2 ) are occasionally seen in the cervix and less frequently in the vagina of rats. They resemble epidermal cysts seen in the skin and have a wall of stratified squamous epithelium, and they may have a central lumen of keratin and variable numbers of inflammatory cells. These cysts are sometimes bilateral. These cysts must be distinguished from focal necrosis or abscess, neither of which would be lined by epithelium. They may arise from vestigial structures. Squamous cysts must be differentiated from squamous metaplasia of the uterus, which is observed within the body away from the cervix or in the horns of the uterus.

## 英文原文 · Recommendation
Squamous cysts occurring in the cervix should be diagnosed as Uterus, Cervix - Cyst, Squamous (in NTP studies, the cervix is classified as a subsite of the uterus). Cysts need not be graded unless grading would help characterize a treatment effect. Inflammatory changes secondary to the cyst should not be diagnosed separately unless warranted by severity.
