Four histological types of appendiceal mucocele have been described: retention cyst, mucosal hyperplasia, mucinous cystadenoma
and mucinous cystadenocarcinoma.
Caption: Minimally invasive minilaparotomy can be used for benign large adnexal mass drainage, as in this case if a mucinous cystadenoma
(1) It is often considered the malignant counterpart to the non-Warthin benign cystadenoma
, and given the former's bland nuclear features and lack of atypia, histological differentiation from cystadenoma
may often be challenging and largely depends on identifying stromal invasion.
topped the list of most common benign ovarian tumours 82(32.8%), benign teratomas 73(29.2%), mucinous cystadenoma
59(23.6%), serous cystadenofibroma 14(5.6%), monodermal tumour 10 (4%), fibrothecoma 5(2%), fibroma 5(2%), and cystadenoma
The average size of the urachal mucinous cystadenoma
was 7.9 cm at greatest dimension, ranging from 1.5 cm to 15.5 cm.
coexisting with adult granulosa cell tumor in the ovary: Is it a composite tumor or heterologous mucinous elements in a granulosa cell tumor?
To better describe the morphologic and immunohistochemical features of primary retroperitoneal mucinous cystadenomas
(PRMCs) and their association with sarcoma-like mural nodules, the authors conducted an immunohistochemical study with a panel of 19 antibodies and a histochemical study for mucin stains.
The macrocystic or oligocystic variant of serous cystadenoma
is uncommon and difficult to distinguish from mucinous cystic neoplasm by imaging.
with mesenchymal stroma: Report of a case and review of the literature.
Warthin's tumor (papillary cystadenoma
lymphomatosum) is the second most common benign lesion of the salivary glands.
, adenofibroma, and surface papillomas are the benign serous tumors.
Cystic luminal distention secondary to obstruction by a mucinous cystadenoma
or cystadenocarcinoma causes the majority of AMC .
