Necrotizing sialometaplasia was defined by Abrams et al. in 1973 as a reactive necrotizing inflammatory process involving minor salivary glands. Prior to recognition of necrotizing sialometaplasia as a benign, self-limited lesion, it was all too often diagnosed as either squamous cell carcinoma or mucoepidermoid carcinoma and had been improperly treated because of its clinical and histological resemblance to malignancy. We report two cases of necrotizing sialometaplasia. One case involved a 56-year-old female who developed a necrotizing sialometaplasia in association with palato-pharyngeal flap wound after excision of soft palate cancer and reconstruction. Another case involved a 55-year-old male who had a soft palate mass.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

Mammary analogue secretory carcinoma (MASC) of the salivary gland is a newly classified pathologic entity since 2010. Prior to its recognition, MASC was diagnosed as low-grade cystadenocarcinoma, acinic cell carcinoma, and mucoepidermoid carcinoma. MASC shares common histological and genetic characteristics with secretory carcinoma of the breast and has a distinct feature of the ETV6-NTRK3 fusion gene. Treatment of MASC in salivary gland is mainly wide surgical resection of the tumor. Prognosis of MASC is similar to other low-grade salivary gland carcinomas. Herein, we report a case of MASC developed in a parotid gland with a review of the literature.

혼합 종양은 상피세포와 근상피세포로 나타나는 경계가 좋은 종양이며 대게 피부와 침샘에서 발생한다. 연조직에서 발생하는 혼합 종양은 극히 드물다. 이에 따라, 연조직에서 발생한 혼합 종양에 대한 영상의학적 소견들은 영상의학 문헌에서 극히 드물게 언급되었다. 그러므로, 저자는 좌측 2번째 손가락의 통증을 주소로 내원한 65세 여자 환자의 손톱 밑 혼합 종양의 증례를 보고하고자 하며, 영상의학적 소견을 기술하고, 감별 진단들에 대해 논의하고자 한다.

Due to the low incidence and histologic diversity of salivary gland cancer, analyzing the incidence of salivary gland cancer is necessary to understand the macroscopic aspects. We intend to investigate the international trend of the reported incidence rate of salivary gland cancer. Using the Korea Central Cancer Registry data, the domestic change in the incidence rate was examined. As a result, a significant increasing trend was confirmed, consistent with the United States and Japan trends. The etiology of the change is unclear, and various factors that may influence the direction are reported. Additional research is needed to understand the pathophysiology of salivary gland cancer, and further efforts are required to understand salivary gland cancer.

To evaluate the quality of fine needle aspiration cytology diagnosis on malignant salivary gland neoplasms, cytologic findings were correlated with histologic diagnosis of 56 surgically removed malignant salivary gland tumors. Seven cases (12.5%) were insufficient, 23 cases (41.1%) were diagnosed as malignant, 17 (30.4%) cases were accurately diagnosed by histologic subtype, and 9 cases (16%) were diagnosed as benign. Five out of 9 false negative cases were misdiagnosed as pleomorphic adenomas. Except the cases with insufficient specimen, overall sensitivity was 81.6%, and the sensitivity varied according to the histologic subtype; 91% in salivary duct carcinoma, 100% in carcinoma ex pleomorphic adenoma, 50% in mucoepidermoid carcinoma, 63% in adenoid cystic carcinoma, and 50% in acinic cell carcinoma. The diagnostic accuracy differed among cytopathologists irrespective of periods after acquisition of board of pathologists. These results confirm that salivary gland neoplasm can be easily misdiagnosed in fine needle aspiration cytology and a great caution should be given in diagnosing the benign appearing salivary aspirates to avoid under-diagnosis of malignant neoplasm with low grade cytologic atypia.

소위 다형선종이라 불리는 혼합종은 주로 침샘에 기원하며 폐에서 발생한 예는 세계적으로 보고된 예가 극히 드물다. 이 신생물은 저악성도를 나타내기도 하나 재발이나 원격전이와 같은 공격적인 성향을 보이는 경우도 있다. 우리는 종양의 완전 절제후 병리학적으로 폐의 일차성 악성 다형선종임을 확인하였고 술 후 다발성 전이와 같은 악성 신생물의 소견을 보이는 증례를 경험하여 이를 보고하는 바이다.

Tumors rarely arise in the sublingual salivary glands. They should be considered malignant until proved otherwise. Adenoid cystic carcinoma is most commonly encountered malignant tumor of the sublingual gland. We report a case of adenoid cystic carcinoma arising from the sublingual gland. Moreover, the sublingual gland had anatomic variation of main duct(Bartholin's duct) which is connected to Wharton's duct.

주로 작은 침샘에서 발생하는 샘낭암종의 치료 방침은 수술과 수술 후 보조적 방사선치료가 주로 행해져 왔다. 그러나 설근부에 발생한 샘낭암종에 대해서는 수술적 치료가 가져오는 삶의 질의 저하가 크기 때문에 수술적 치료를 적용하기 쉽지 않다. 또한 샘낭암종의 치료에 있어서 항암제의 역할이 거의 없는 상황에서 방사선치료가 중요한 역할을 할 수 있겠다. 이에 본 저자들은 설근부에 발생한 샘낭암종 세 증례의 방사선치료 결과를 보고 하며 샘낭암종의 치료에 대해서 문헌고찰을 통해 논의하고자 한다.

Angiosarcoma is a rare and highly malignant neoplasm which develops from the endothelium of blood vessels. A few cases of primary angiosarcoma of the parotid gland have been reported. However, there is no report of primary angiosarcoma of the accessory parotid gland. In this case, we report a primary angiosarcoma of the accessory parotid gland in a 45-year-old man with growing cheek mass. Ultrasonography revealed a $2.0{\times}2.6cm$ sized homogeneous hypoechoic mass and computed tomography showed a contrast enhanced homogeneous mass. Fine needle aspiration biopsy suggested a benign tumor. The mass was completely excised with a minimal vertical incision. The histopathology showed anastomosing vascular channels lined by atypical endothelial cells and many branching vessels with staghorn appearance with positive immunohistochemical staining for CD34, a highly specific endothelial marker. The patient underwent postoperative radiotherapy and was followed for 8 years without recurrence and metastasis.
