Pancreatic adenomas, including plasma cystadenomas and neuroendocrine microadenomas, are mostly benign lesions, usually asymptomatic, and treatment is based on surgical resection. Pancreatic adenomas are usually benign neoplastic lesions of the pancreas, including oligocystic plasma cystadenomas, solid plasma cystadenomas and other plasma cystadenomas, as well as neuroendocrine microadenomas. This type of tumor is clinically rare, mostly seen in women, and the tumor marker CA199 is usually not elevated. Ultrasound and CT examinations show cystic, regular lesions in the pancreas, which may appear as honeycomb-like structures. Pathologic puncture is performed to visualize clear, mucus-free contents. The disease usually has no obvious clinical manifestations, and a few lesions may be characterized by abdominal masses and jaundice. The treatment of this disease is mainly based on surgery. If pancreatic adenoma is suspected, it is recommended to go to the hospital in time.
