Pancreatic cystadenoma is a very rare slow-growing cystic lesion that only about 350 cases were reported in the literlatures. The lesions occur predominantly in late middle aged woman characterized by a slowly growing palpable mass in the epigastrium. The etiology of the cyst- adenoma is still obscure. Pancreatic mucinous cystadenoma occur predominantly in the tail and the body of the pancreas. Pancreatic mucinous cystadenoma has a definite malignant po- tential in contrast to microcystic(serous) cystadenoma which is benign and then total excision is the ideal treatment for pancreatic mucinous cystadenoma. A 54 year old woman patient was admitted to this hospital with the complaints of epigastric discomfort and the discovery of a slow-growing palpable mass in left upper quadrant abdomen for the preceding 7 years. Exploratory laparatomy was performed which disclosed a smooth cystic mass about 15cm in diameter in the tail of the pancreas. The cut surface of the turnor showed multiple cyst containing gray mucinous fluid. The mass was adhered to the stomach and jejunum. For the complete excision of the tumor, distal pancreatectomy and splenectomy were performed. Histopathological examination confirmed the mucinous cystadenoma of the pancreas.(Korean J Gastroenterol 1994; 26: 210 213)

Primary retroperitoneal mucinous cystadenoma is an extremely uncommon tumor, even though mucinous cystadenoma often develops in the ovary and less frequently in the pancreas. A 21-year-old female was admitted to our hospital due to severe abdominal pain. A well-demarcated, oval shaped cystic tumor at the retropancreatic area with displacement of the pancreas and surrounding major vessels was observed on CT and MRI. Exploratory laparotomy was performed, and complete excision of the entire cyst was performed without complication. The pathologic finding was consistent with primary retropancreatic mucinous cystadenoma. To the best of our knowledge, this report is the first to describe a case of retropancreatic mucinous cystadenoma arising from the retropancreatic area in Korea.
Mucinous Cystadenoma of the Testis: A Case Report with Immunohistochemical Findings
김길향,문경철,권도희,나희영,김세희 대한병리학회 2017 Journal of Pathology and Translational Medicine Vol.51 No.2
Mucinous cystadenoma of the testis is a very rare tumor. Herein, we report a case of mucinous cystadenoma arising in the testis of a 61-year-old man, along with a literature review. Computed tomography showed a 2.5-cm-sized poorly enhancing cystic mass. Grossly, the tumor was a unilocular cystic mass filled with mucinous material and confined to the testicular parenchyma. Histologically, the cyst had a fibrotic wall lined by mucinous columnar epithelium without atypia. Immunohistochemical staining was positive for cytokeratin 20 and CDX2, as well as focally positive for cytokeratin 7. The pathologic diagnosis was mucinous cystadenoma.

Primary retroperitoneal mucinous cystadenomas are rare tumors that are almost always found in women. They are similar to ovarian originated mucinous cystadenoma, but there is no any other evidence of an ovarian origin for primary retroperitoneal mucinous cystadenomas. A 33-year-old woman with complaints of RLQ pain was found to have a cystic mass in the right retroperitoneal space on her abdominal CT scan. The histological diagnosis was confirmed as primary mucinous cystadenoma. We report here on a case of retroperitoneal mucinous cystadenoma, and we also talk about this tumor, including its histogenesis, through a review of the available literature.
Primary Retroperitoneal Mucinous Cystadenoma
이석윤,한원철 대한대장항문학회 2016 Annals of Coloproctolgy Vol.32 No.1
Mucinous cystadenomas and cystadenocarcinomas of the ovary are clinically and histopathologically well-established common tumors. However, primary retroperitoneal mucinous cystic tumors are extremely rare, and although their histopathogenesis is still uncertain, several theories have been proposed. Most authors suggest that they develop through mucinous metaplasia in a preexisting mesothelium-lined cyst. An accurate preoperative diagnosis of these tumors is difficult because no effective diagnostic measures have been established. Delay in diagnosis and treatment of this tumor may be fatal for the patient because of complications such as rupture, infection, and malignant transformation. We describe the case of a 31-year-old woman with abdominal pain and a palpable mass. Computed tomography of the abdomen revealed a retroperitoneal cystic mass, which was resected successfully through laparoscopy. Histopathological examination of the resected mass confirmed the diagnosis of a primary retroperitoneal mucinous cystadenoma. The patient was discharged on postoperative day 5 without any complications.
Urachal Mucinous Tumor of Uncertain Malignant Potential: A Case Report
최정우,김영식,이주한 대한병리학회 2012 Journal of Pathology and Translational Medicine Vol.46 No.1
Urachal mucinous tumor of uncertain malignant potential is very rare and is characterized by a multilocular cyst showing the proliferation of atypical mucin-secreting cells without stromal invasion. As in ovarian and appendiceal borderline tumors, it represents a transitional stage of mucinous carcinogenesis in the urachus. In addition, this tumor may recur locally and develop into pseudomyxoma peritonei. Due to its scarcity and diagnostic challenges, we report a mucinous tumor of uncertain malignant potential arising in the urachus.
Case Report : Abnormally high level of CA-19-9 in a benign ovarian cyst
( Seung Yeon Pyeon ),( Ji Young Park ),( Kyung Do Ki ),( Jong Min Lee ) 대한산부인과학회 2015 Obstetrics & Gynecology Science Vol.58 No.6
CA-19-9 antigen is mainly elevated in cases of gastrointestinal tract malignancy, including of the pancreas, colorectum, and biliary tract. CA 19-9 antigen can also be elevated in ovarian mucinous neoplasms, however, as well as in many benign conditions. Markedly raised levels of more than 10,000 U/mL were almost observed in advanced stage of malignancy. We report herein the case of a 37-year-old woman who presented with an abnormally high level of CA 19-9 antigen associated with benign mucinous cystadenoma.

Mucinous cystadenomas are relatively common tumors in visceral organs and most of them are located in ovary and pancreas. But no report of the mucinous cystadenoma arising from the salivary gland is available at present. Clinical characteristics of the tumors show asymptomatic mass and rare malignant transformation. Histopathologically, the mucinous cystadenoma commonly appears as a cyst filled with mucin and the lining of cyst is composed of tall columnar epithelium. We performed a superficial parotidectomy in a patient with a parotid tumor which was diagnosed as a mucinous cystadenoma postoperatively, but we could not found the same tumor in visceral organs. The patient was observed over 6 months without any evidence of recurrence. This report describe a unique case of a typical mucinous cystadenoma found in the parotid galnd without involvement of the other organs.
Multiple bilateral malar mucinous cystadenomas in the minor salivary glands
Choi, Jun Ho,Kim, Seung Hyun,Hwang, Jae Ha,Kim, Kwang Seog,Lee, Sam Yong Korean Cleft Palate-Craniofacial Association 2020 Archives of Craniofacial Surgery Vol.21 No.5
Mucinous cystadenoma, one of the subtypes of cystadenomas, is a rare benign salivary gland tumor. Most of the cases reported tumors presenting as asymptomatic, slow growing, single masses, primarily occurring in the parotid glands, buccal mucosa, and hard palate. This report describes a case of multiple mucinous cystadenomas that presented as subcutaneous swellings in both cheeks, which were mistaken for a benign subcutaneous tumor. A complete surgical excision was performed through an intraoral incision. There were no recurrences or complications. A diagnosis of mucinous cystadenoma was made by histopathological examination. Mucinous cystadenomas are differentiated from other salivary gland tumors based on the pathological findings. A malignant transformation is also possible. Preoperative imaging cannot identify mucinous cystadenomas because of their small size and atypical features, and needle biopsy has its limitations in such salivary gland tumors. Therefore, accurate diagnosis and treatment through surgical excision become important.
