## 一句话结论
舌内的囊性唾液腺导管（也称为舌下囊肿）衬以低立方上皮，与唾液腺导管一致（不同于唾液腺黏液囊肿，后者为充满唾液分泌物的囊性腔隙，但无上皮衬覆）。

## 病变描述（中文）
舌内的囊性唾液腺导管（也称为舌下囊肿）衬以低立方上皮，与唾液腺导管一致（不同于唾液腺黏液囊肿，后者为充满唾液分泌物的囊性腔隙，但无上皮衬覆）。唾液腺导管囊肿（Figure 1、Figure 2）可能充满淡嗜酸性液体，但该液体在制片过程中可能丢失，留下空囊肿。囊肿、扩张或黏液囊肿可能继发于创伤、唾液腺结石或小导管异物，被视为偶然发现。破裂的囊肿可能伴有炎症，常为肉芽肿性。它们在F344/N rat和B6C3F1 mouse中罕见。

## 诊断与分级建议（NTP 共识，中文）
舌内唾液腺导管囊肿和扩张无论何时出现均应诊断，但通常不分级。若病变小，诊断为扩张；较大的病变诊断为囊肿。若有相关炎症，除非炎症的严重程度需要，否则不单独记录炎症。

## 英文原文 · Comment
Cystic salivary ducts in the tongue (also known as ranulae) are lined by low cuboidal epithelium consistent with the salivary duct (as opposed to salivary mucoceles, which are cystic cavities filled with salivary secretions but not lined by an epithelium). Salivary gland duct cysts ( Figure 1 and Figure 2 ) may be filled with pale eosinophilic fluid, but the fluid can be lost in processing, leaving an empty cyst. Cysts, dilations, or mucoceles may occur secondary to trauma, salivary calculi, or ductular foreign bodies and are considered incidental findings. Ruptured cysts may be accompanied by inflammation, often granulomatous. They are rare in F344/N rats and B6C3F1 mice.

## 英文原文 · Recommendation
Whenever present, salivary duct cysts and dilations in the tongue should be diagnosed, but they are not generally graded. If the lesion is small, is diagnosed as dilation; larger lesions are diagnosed as cysts. If there is associated inflammation, the inflammation is not recorded separately unless warranted by severity.
