摘要


黏液表皮樣細胞癌發生在上唇是非常罕見,經由醫學文獻分析檢索系統發現,目前為止僅有四個下唇之黏液表皮樣細胞癌病例被報導,而且關於發生在上唇邊緣的病例則更為罕見。本科經歷一位57歲男性病患,其上唇中線位置有一無壓痛感的腫瘤,且此腫瘤已經存在30年之久,然而最近1個月卻發現腫瘤有逐漸變大及潰瘍的情形,於是病人接受切除手術治療。手術治療後該病人持續追蹤觀察17個月後,發現於患處並無復發或轉移跡象,目前仍持續門診追蹤。截至目前為止並無報導論述關於發生在上唇邊緣之黏液表皮樣細胞癌,且對於其形成的原因並不是十分的清楚。而以手術完全切除黏液表皮樣細胞癌的治療方式,通常能獲得良好的預後結果。儘管上唇之黏液表皮樣細胞癌非常罕見,但仍建議將其與上唇的腫瘤作一區分鑑別診斷。

Mucoepidermoid carcinoma occurring in the upper lip is extremely rare. A review of the English literature on mucoepidermoid carcinoma found only four reported cases in the lower lip, and none on the vermilion border of the upper lip. We present a 57-year-old patient who had an asymptomatic lesion on the middle upper lip for 30 years. It had grown progressively and had ulcerated over 1 month ago; the tumor was treated by M-excision. After 17 months of post-therapy, the patient had no local recurrence or distant metastasis. Mucoepidermoid carcinoma is a rare malignancy on the vermilion border of the upper lip with no reported cases to date. The origins of this tumor are not completely understood. Complete resection of the mucoepidermoid carcinoma usually achieves a successful outcome. Although very rare, mucoepidermoid carcinoma should be taken into consideration in the differential diagnosis of any upper lip mass.
