扩张Dilation · 精囊 · 雄性生殖系统 · NTP ntp-0481
诊断要点:扩张应记录并分级。如果双侧精囊均受累,诊断应限定为双侧(双侧(bilateral)),严重程度分级由受累更严重的精囊确定。
病变描述
精囊扩张(dilation of seminal vesicles)表现为腺体因分泌物质而膨胀(Figure 1、Figure 2)。上皮细胞和乳头状皱襞变扁平并减少(箭头,Figure 1、Figure 2)。扩张可能与阻塞有关,并可能导致分泌物浓缩(inspissation)。精囊扩张通常与年龄较大相关。
诊断与分级建议(NTP 共识)
扩张应记录并分级。如果双侧精囊均受累,诊断应限定为双侧(双侧(bilateral)),严重程度分级由受累更严重的精囊确定。

Comment:
Dilation of seminal vesicles consists of distension of the gland with secretory material ( Figure 1 and Figure 2 ). The epithelial cells and the papillary folds are flattened and reduced (arrows, Figure 1 and Figure 2 ). Dilation may be associated with obstruction and may lead to inspissation. Seminal vesicle dilation is usually associated with older age.
Recommendation:
Dilation should be recorded and graded. If both seminal vesicles are involved, the diagnosis should be qualified as bilateral and the severity grade determined by the more severely affect seminal vesicle.
