What is Microcystic serous cystadenoma?

What is Microcystic serous cystadenoma?

Microcystic adenoma or serous cystadenoma is an uncommon tumor and accounts for 1-2% of the exocrine neoplasms of the pancreas. Usually unifocal, they present as single, large, well-demarcated multiloculated cystic tumors, ranging in size from 1 to 25 cm.

What is a serous cystadenoma pancreas?

Pancreatic serous cystadenoma is a benign tumour of pancreas. It is usually found in the tail of the pancreas, and may be associated with von Hippel-Lindau syndrome.

What is Microcystic adenoma?

Microcystic adenoma is a benign pancreatic tumor that arises from acinar cells. The tumor contains multiple small cysts lined with cuboidal cellsand containing serous fluid. The fluid is positive at glycogen staining (periodic acid Schiff reaction) (,1,,4).

Why can a Microcystic serous cystadenoma of the pancreas have a solid appearance on ultrasound?

The fibrous portion of the lesion is hyperechoic, and the cystic portions appear hypoechoic. In lesions where the cysts are only a couple of millimeters in size (microcysts), the tumor appears solid due to the innumerable interfaces. Areas of calcification also appear hyperechoic with posterior acoustic shadowing.

How fast does a serous cystadenoma grow?

Although the median growth rate for this neoplasm is only 0.6 cm/y, it is significantly greater in large tumors. Whereas expectant management is reasonable in small asymptomatic tumors, we recommend resection for large serous cystadenomas regardless of the presence or absence of symptoms.

How common is serous cystadenoma?

Serous cystadenoma is more common than mucinous cystic neoplasm, with a ratio of about 2:1.

What is Microcystic?

Microcystic adnexal carcinoma is a rare tumor of the skin that most often develops in the head and neck region, particularly in the middle of the face, though it may occur in the skin of other parts of the body as well. The average age of diagnosis is 56.

What causes pancreatic serous cystadenoma?

Pseudocysts are not cancerous (benign) and are usually caused by pancreatitis. Pancreatic pseudocysts can also be caused by trauma. Serous cystadenomas can become large enough to displace nearby organs, causing abdominal pain and a feeling of fullness.

What causes a serous cystadenoma?

What is a serous cystadenoma? A serous cystadenoma is a very common non-cancerous type of ovarian tumour. It develops from the cells on the surface of the ovary. While these tumours are non-cancerous, they can grow to be very large in size and as a result can cause significant symptoms for many patients.

How is serous cystadenoma treated?

Preoperative diagnosis of this subtype of serous cystadenoma is difficult, and, due to its benign nature, conservative resection of the tumor is the recommended treatment.
