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.

Incidental pancreatic cystic lesions are a common challenge encountered by diagnostic radiologists. Specifically, given the prevalence of benign pancreatic cystic lesions, determining when to recommend aggressive actions such as surgical resection or endoscopic ultrasound with sampling is difficult. In this article, we review the common types of cystic pancreatic lesions including serous cystadenoma, intraductal papillary mucinous neoplasm, and mucinous cystic neoplasm with imaging examples of each. We also discuss high-risk or worrisome imaging features that warrant a referral to a surgeon or endoscopist and provid several examples of these features. These imaging features adhere to the latest guidelines from the International Consensus Guidelines, American Gastroenterological Association (2015), American College of Gastroenterology (2018), American College of Radiology (2010, 2017), and European Guidelines (2013, 2018). Our focused article addresses the imaging dilemma of managing incidental cystic pancreatic lesions, weighing the options between imaging follow-up and aggressive interventions.

동물원에서 사육 중이던 7세령 암컷 일본원숭이가 짝짓기 과정에서 피부에 외상을 입은 후 치료 도중 폐사하였다. 부검시 간에서 $1.3\times1.2\times1.0cm$ 크기를 비롯한 다양한 크기의 다발성 낭포가 관찰되었으며 낭포내에 점액성 액체가 저류되어 있었다. 현미경 소견상 낭포는 담관 상피세포로 덮혀 있었고 입방상피에서 원주상피까지 다양하였으며 대부분 단층이었으나 일부는 여러층으로 덮혀 있었다. 악성도나 다른 장기로의 전이 소견은 찾을 수 없었다. 본 증례는 일본 원숭이에서 발견된 첫 번째 담관 낭샘종 증례이다.
