导管凝结物Duct Concretion · 唾液腺 · 消化系统 · NTP ntp-0234
诊断要点:唾液腺导管中的凝结物只要存在就应诊断。除非分级能揭示处理效应,否则无需分级。继发性病变,如扩张、炎症和纤维化,除非严重程度需要,否则无需单独诊断。
病变描述
凝结物(导管腔内物质的矿化)不常发生,但最常见于年龄较大的动物,作为背景性病变。它们可能与萎缩同时出现。凝结物或异物可导致导管扩张、炎症和纤维化。
诊断与分级建议(NTP 共识)
唾液腺导管中的凝结物只要存在就应诊断。除非分级能揭示处理效应,否则无需分级。继发性病变,如扩张、炎症和纤维化,除非严重程度需要,否则无需单独诊断。

Comment:
Concretions (mineralization of material in the ductular lumen) occur infrequently but are most commonly seen in older animals as a background lesion. They may be seen with atrophy. Concretions or foreign bodies can lead to duct dilation, inflammation, and fibrosis.
Recommendation:
A concretion in a salivary duct should be diagnosed whenever present. They need not be graded unless grading would divulge a treatment effect. Secondary lesions, such as dilation, inflammation, and fibrosis, need not be diagnosed separately unless warranted by severity.
