导管囊肿Duct Cyst · 唾液腺 · 消化系统 · NTP ntp-0235
诊断要点:导管囊肿应当诊断,但一般不进行分级,除非囊肿大小存在与处理相关的影响。如果存在导管上皮的鳞状化生(squamous metaplasia),应当单独诊断并分级。
病变描述
唾液腺导管囊肿(salivary gland duct cyst)往往累及一条或少数几条导管,通常呈圆形轮廓(Figure 1),而唾液腺的导管扩张(ductular dilation)通常更为弥漫(累及多条导管),且导管往往呈不规则轮廓(见 Salivary Gland - Duct - Dilation)。囊肿可能由结石、创伤或异物阻塞导管所致。导管扩张和导管囊肿在 NTP 啮齿类动物研究中不常见。
诊断与分级建议(NTP 共识)
导管囊肿应当诊断,但一般不进行分级,除非囊肿大小存在与处理相关的影响。如果存在导管上皮的鳞状化生(squamous metaplasia),应当单独诊断并分级。相关链接:Salivary Gland - Duct - Dilation

Comment:
Salivary gland duct cysts tend to involve one or a few ducts and usually have a circular profile ( Figure 1 ), whereas ductular dilation of salivary glands is typically more generalized (involving multiple ducts), and the ducts tend to have an irregular profile (see Salivary Gland - Duct - Dilation ). Cysts may be caused by obstruction of a duct by calculi, trauma, or foreign body. Ductular dilation and ductular cysts are not common in NTP rodent studies.
Recommendation:
Duct cysts should be diagnosed but are generally not graded unless there is a treatment-related effect on the size of the cysts. If squamous metaplasia of the ductal epithelium is present, it should be diagnosed and graded separately. Related Links: Salivary Gland - Duct - Dilation
