下頷腺之皮脂性淋巴腺瘤－病例報告
Sebaceous Lymphadenoma of the Submandibular Gland - Case Report
摘要
皮脂性淋巴腺瘤是罕見的唾液腺腫瘤，尤其在下頷腺中更是少見。皮脂性分化(sebaceous differentiation)可以出現在正常、發炎或腫瘤性的唾液腺，因此由唾液腺或頸部淋巴結中的多功能腺管細胞(pluripotential duct cell)所發展的腫瘤若結合皮脂性分化即成為皮脂腫瘤。由於無臨床特殊表徵，此病必須以病理組織檢查診斷；手術切除腫瘤是主要治療方式，少有復發情形，預後良好。長庚醫院耳鼻喉科於民國83年6月經歷此一罕見病例，患者在右下頷側出現腫瘤，電腦斷層掃描顯示囊性變化之下頷腺瘤，經手術將腫瘤完全切除，門診追蹤恢復情況良好無再發現象。謹提出此報告。
並列摘要
Sebaceous lymphadenoma is a rare benign tumor of the salivary gland, and is rarely found in the submandibular gland. Sebaceous differentiation may arise in the normal, inflammatory or tumoral salivary gland. A sebaceous lymphadenoma is considered to arise from the pluripotential duct cell of the salivary gland or ectopic ductal remnants in the neck lymph nodes. Because there is no special clinical feature, the tumor can only be diagnosed by the pathologic examination. Surgical excision of the tumor is the treatment of choice. The tumor is benign and the prognosis is good. We experienced such a case in our hospital and the patient had a history of right submandibular mass for 3 months. Head and neck CT revealed a polycystic tumor of the right submandibular gland. After surgical excision of the tumor, the patient recovered well without tumor recurrence. The detailed clinical and pathologic findings will be reported herein with a review of the literature.
