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. ## 英文原文 · 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.
