腮腺唾液管之腺癌-兩例報告

Ductal Adenocarcinoma of the Parotid Gland - Report of Two Cases

摘要


唾液腺的管線癌(salivary duct adenocarcinoma)相當罕見。自Kleinsasser 等於1968年提出,稱為Speichelgangearcarcinom,至今報告50餘例。唾液管線癌最大特徵就是組織病理學的細胞表徵和乳房、攝護腺的管腺癌(ductal carcinomas)類似,而且臨床表徵上極具侵襲性,大約半數患者有局部復發及淋巴結轉移,三分之二的患者有遠處轉移,所以預後不佳。馬偕紀念醫院耳鼻喉科於民國81年10月和82年1月經歷兩例腮腺管腺癌,皆接受腮腺全葉和局部淋巴結切除,並於術後放射治療,至今無局部復發及遠處轉移現象。

Salivary duct adenocarcinoma is a rare neoplasn frist described by Kleinsasser et al in 1968 “Speichelgangearcarcinom”. This tumor is characterized by its pathohis - tologic resemblance to ductal carcinomas of the breast and the prostate, and by a highly aggressive biologic behavior. We reported two cases of ductal adenocarcinoma affecting the parotid parotid gland. Total parotidectomy, regional lymph node resection and subsequent radiotherapy were performed. There were still no signs of local recurrence or distant metastases 5 months and 2 months after treatment respectiveky. The literature concerning this rare tumor was reviewed, and the character – istic pathohistology and prognosis were discussed.
