BACKGROUND
Intraductal carcinoma is a rare low grade neoplasm of salivary glands with an excellent prognosis. It most frequently occurs in the parotid gland. Ectopic localizations are quite rare.
METHODS
This case report describes a man in his 60's who was referred to ear, nose and throat outpatient department with 1-month history of painless swelling of the right parotid region.
RESULTS
Ultrasound-guided fine-needle aspiration unveiled a cytologic specimen judged as "suspicious for malignancy" and patient underwent a partial superficial parotidectomy. Immunohistochemistry confirmed diagnosis of intraductal carcinoma of right parotid gland.
CONCLUSIONS
There are few reported cases concerning this clinical entity following thorough review of the literature and recent developments with reference to the contribution of cytology and histopathology will probably modify its classification and management.
背景
导管内癌是一种罕见的低级别涎腺癌，具有良好的预后。它最常发生在腮腺。异位定位相当罕见。
方法
本病例报告描述了一位 60 多岁的男性，他因右腮腺无痛性肿胀 1 个月而被转至耳鼻喉科门诊。
结果
超声引导下细针抽吸显示细胞学标本被判断为“恶性可疑”，患者接受了部分腮腺浅叶切除术。免疫组织化学证实了右侧腮腺导管内癌的诊断。
结论
通过彻底复习文献和参考细胞学和组织病理学的最新进展，发现了少数关于这种临床实体的报道，这可能会改变其分类和管理。
