Papillary cystadenoma is a rare, benign salivary gland neoplasm containing cystic cavities with intraluminal papillary projections. In the head and neck area, it occurs mainly in major and intraoral minor salivary glands, but rarely in the larynx. We report a case of a 67-year-old female with a chief complaint of hoarse voice diagnosed as laryngeal papillary cystadenoma. This paper emphasizes the need to consider papillary cystadenoma as one of differential diagnosis when benign looking lesions are observed in the larynx, where it uncommonly occurs.

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.

Warthin's tumour is also known as papillary cystadenoma lymphomatosum or adenolymphoma. This tumour represents 6% of all salivary gland tumour, and is the second most common neoplasm of the salivary gland. It occurs mostly in the parotid gland and in rare instances, it has been reported to occur within the submandibular gland or minor salivary glands. In the past, there was higher incidence in males than females, but more recent investigation shows a more balanced sex predilection. The mean age at diagnosis is 62 years and this tumour is uncommon in a patients younger than age 40. This tumour occurs most frequently in the tail of the parotid gland near the angle of the mandible. Surgical removal is the treatment of choice. But sometimes, parotidectomy is recommended because of its potential for being multifocal.

Cystadenocarcinoma of the salivary glands is a very rare, slow growing, and low-grade malignant neoplasm. It is characterized by predominantly cystic growth with or without the intraluminal papillary component. However, it lacks of any additional specific histopathologic features that characterize other types of salivary carcinomas showing cystic growth. Therefore, definite diagnosis of the cystadenocarcinoma is difficult and it is often misdiagnosed. It is conceptually the malignant counterpart of the benign cystadenoma. We present a cystadenocarcinoma on the palate of a 49-year-old man with special emphasis on magnetic resonance imaging.

Warthintumor (WT), also known as adenolymphoma or papillary cystadenoma lymphomatosum, was described in 1895 for the first time. It is a common benign tumor of the parotid glands and the second most common neoplasm of the salivary gland, accounting for 5% to 14% of all parotid neoplasm. A 63-year-old man visited our clinic with the complaint of swelling on the right parotid gland. Physical examination showed a 3 cm, firm, well-circumscribed, painless mass on the right mandibular angle. Computed tomography imaging showed a $3.5{\times}2.0{\times}1.6$ cm well-defined cystic mass. WT is histologically characterized by bilayered, oncocystic cell, lymphoid stroma, and cystic space. With these typical cytomorphologic characteristics, the fine-needle aspiration cytology was performed as diagnostic tool before the surgery. The lymphocytes and oncocystic cell were not observed. The lesion was completely excised under general anesthesia. We diagnosed the case as WT, from the surgically excised specimen. We report on the case with a review of the literatures.

Warthin's tumor is the second most common salivary gland benign tumor, typically occurring in the fifth to seventh decades of life which shows an indolent feature. It is usually found in the parotid gland but occasionally in extra-parotid locations such as peri-parotid lymph node. However, Report of solitary Warthin's tumor in cervical lymph node is unusual. We here report a case of 72-year-old male with simultaneous malignant melanoma on eyelid and cervical lymph node enlargement in cervical level II area thus mimicking malignancy metastasis. After excisional biopsy under the local anesthesia, pathology was reported as papillary cystadenoma lymphomatosum, which is a histologically pathognomic finding of Warthin's tumor. However, there was no suspicious tumorous lesion in major or minor salivary glands. This case suggests that Warthin's tumor should be considered as a possible pathology in solitary lymph node lesion of neck.
