Sialadenoma papilliferum is a rare benign salivary gland tumor, accounting for approximately 0.4–1.2% of all salivary gland neoplasms. It most commonly occurs in the hard palate, followed by the soft palate, buccal mucosa, upper lip, and, rarely, the esophagus. The condition is typically asymptomatic and is often discovered incidentally during routine oral examinations. We report the case of a 56-year-old man who presented with pain in the left hard palate and was referred to Kyungpook National University Dental Hospital. Enhanced CT revealed a 1.5-cm ovoid lesion in the left paramedian hard palate. Biopsy confirmed the diagnosis of sialadenoma papilliferum, and based on the radiological findings, surgical excision was performed under general anesthesia. The microscopic histopathological examination of the specimen (size: 1.0 x 0.7 cm) revealed papillary proliferation of stratified squamous epithelium with hyperkeratosis and underlying ductal structures lined by mucin-producing cells with mucinous material in the cystic spaces.

In China, the meditation hall, where monks practice meditation, eat, and sleep together, appeared around the 8th to 9th centuries. The specific functions and architectural forms of the meditation hall are known by the Cheonggyu(淸規) compiled and disseminated during the Song Dynasty, when Seon Buddhism was most prosperous, and by materials recorded by Japanese monks of that time. The temple system of the Seon Buddhism temples of the Song Dynasty, including meditation hall, was transmitted to Japan at the time and had a great influence on the formation of Seon Buddhism temples in the Middle Ages. On the other hand, in Korea, until the late Goryeo Dynasty, unlike in China or Japan at the time, the meditation hall was used only for meditation practice, and the dining hall and a building called Seungmu(僧廡) for sleeping and daily life were built separately. And the meditation hall was equipped with a heating system unique to Korea called Gudeul. The meditation hall of Hoeamsa Temple, which was rebuilt by Naong(懶翁) in the end of the Goryeo Dynasty by introducing the temple system of Chinese Seon Buddhism temples, took on the general appearance of East Asian Seon Buddhism temples, but it also maintained the characteristics of Goryeo Buddhism architecture.

Although fine-needle aspiration biopsy (FNAB) has been widely accepted as a valuable tool for differential diagnosis of head and neck tumors, the diagnostic value of FNAB in the management of salivary gland tumors has been questioned. This case report presents a patient with mucoepidermoid carcinoma of parotid gland diagnosed as pleomorphic adenoma by FNAB and discusses the pitfalls in the diagnosis of malignant salivary gland tumors.

Multiple endocrine neoplasia type 2B (MEN2B), which is an autosomal dominant hamartoneoplastic syndrome, is a genetic syndrome. Patients with this syndrome are characterized by multiple mucosal neuromas on the tongue, lips, eyelid margins, and conjunctiva with marfanoid habitus, thick and protruding lips, open bite, and maxillary central diastema. Multiple oral mucosal neuromas are known to appear before the development of medullary thyroid carcinoma (MTC) or pheochromocytoma. Therefore, understanding the oral symptoms is very important for the early diagnosis of this syndrome. We report multiple submucosal neuromas in a 19-year-old male patient diagnosed with MEN2B and review this syndrome.

Engaged in trawling in limited fishing grounds with a number of fish schools could cause collisions between fishing vessels. Therefore, providing accurate maneuver information according to the situation could be regarded as essential for improving seafarers safety and fishing efficiency as well as safety of navigation. It is difficult to obtain all maneuver information through sea trial tests only, so a method through empirical formula is necessary. Since most empirical formulas are developed for merchant ship types, especially the characteristics of hull shape parameter like CbB/L and dCb/B etc. are clearly different between fishing vessels and merchant ships, this could occur estimation errors. Therefore, in this study, the authors have selected target fishing vessels and merchant ships and analyzed the characteristics of hull shape parameter according to the ship types. Based on this analysis, the empirical formula developed for the merchant ship type has applied to the target fishing vessels; it has verified through the turning motion simulation that the estimation error could be generated. In conclusion, it is necessary to include the characteristics of the hull shape parameter of fishing vessels in the empirical formula in order to apply the empirical formula has developed for merchant ship types to fishing vessel types.

“Cartilaginous choristoma” refers to as a tumorlike cartilaginous mass composed of normal tissues in an abnormal location. Oral cartilaginous choristomas are extremely rare. Although its rarity, most intraoral choristomas occur in the tongue. Adenomatoid hyperplasia of the minor salivary glands may be seen on the minor salivary gland bearing areas, especially seen on the palate. This report describes a case of firm mass on the left lateral tongue that was resulted cartilaginous choristoma associated with adenomatoid hyperplasia, which occurred in a 23-year-old male patient. And It hasn’t recurred during 17 months after complete excision.

Canalicular adenoma is an uncommon, benign salivary gland tumor. It has a significant predilection for occurrence in the minor salivary glands, with most cases occurring in the upper lip, followed by the buccal mucosa and palate. Rarely, canalicular adenoma can involve the major salivary glands, such as the parotid gland. Only a small number of cases of canalicular adenoma of the parotid gland have been reported in the literature. We report a rare case of canalicular adenoma on the left parotid gland of an 81-year-old man, and present a review of the literature.

The most common benign salivary gland tumor is pleomorphic adenoma. It affects major and minor salivary glands. Minor salivary gland tumors constitute <20% of all salivary gland neoplasms. Most minor salivary gland tumors occur on the palate. We present the case of a patient with pleomorphic adenoma that developed at a rare intraoral location. This patient presented to the Department of Oral and Maxillofacial Surgery of Seoul National University Dental Hospital.

Pleomorphic adenoma is the most common benign tumor of the salivary glands. About 80-90% of pleomorphic adenoma occurs in the parotid gland and about 5-10% of them occur in the submandibular gland and sublingual gland. The rest proportion comprises the minor salivary glands. The palate is the most common area, followed by the lips and the cheeks. Pleomorphic adenoma of the submandibular gland shows clinically a slow-growing, painless mass found on submandibular aspect. In this case report, we report a case of pleomorphic adenoma of the right submandibular gland in a 63-year old female patient who was referred from the department of neurosurgery, due to the heterogenous mass detected by computed tomography (CT) and magnetic resonance imaging (MRI)

The purpose of this study is to clarify the historical background of the setting of seungdang(僧堂) and gowon (庫院) in the Zen Buddhist temples of Song dynasty, in terms of as a Buddhist temple universality and as a Zen temple specificity, through the historical reference investigation on its relevance to the Buddhist temples of Tang dynasty. In the Zen Buddhist temples of Song dynasty, the Zen meditation space of seungdang was located on the west side of Buddha hall, and the kitchen and officiating priest’s living space of gowon was located on the east side of Buddha hall. Through the analysis of historical reference it was confirmed that, in the Buddhist temples of Tang dynasty, the Zen meditation section of seonwon(禪院) was on the west side, and the gowon was on the east side too. Therefore, it can be said that, the setting method of seungdang and gowon of the Zen Buddhist temples of Song dynasty was established above tradition of the Tang dynasty Buddhist temples.

The purpose of this study is to clarify the characteristics of Zen Buddhist temple’s building composition of the Northern Song dynasty, through the analysis of literature historical material, such as Seonwon chenggyu(禪苑淸 規), Cham cheontae odaesan gi (參天台五臺山記) and so on. The building composition method of Zen Buddhist temple in Northern Song dynasty, which grasped from the Seonwon chenggyu, reflects the actual situation of the temples in that time. And it was ascertained that, the Zen Buddhist temple’s building composition of the Northern Song dynasty was basically same to that of Southern Song dynasty. And the comparative analysis was attempted between Zen Buddhist temples and that of other Buddhism sect described in Cham cheontae odaesan gi. From this analysis, the common features as Buddhism temple and the characteristics of building composition as Zen Buddhist temple was clarified.

Pleomorphic adenoma is the most common benign tumor of the salivary glands. About 90% of these tumors occur in the parotid gland and 10% of them occur in the minor salivary glands. The most common sites for pleomorphic adenoma of the minor salivary glands are the palate, followed by the lips and the cheeks. Pleomorphic adenoma of the palate presents clinically as a painless, slow-growing mass found on posterior lateral aspect. In this case report, we report a case of pleomorphic adenoma of the palate in a 36-year old male patient whose initial diagnosis was vascular mass such as hemangioma or lymphangiohemangioma by preoperative CT and MRI.
