摘要

多形性腺瘤通常起源於唾液腺，最常是腮腺。而發生於耳郭部之多形性腺瘤極少見。本科於1999年11月經歷1名82歲男性病患，主訴左側耳郭有一逐漸增大腫塊已4個月，門診檢查發現，在左耳耳輪中央1/3外側部有一如花生米大小、界限清楚之皮下圓形硬塊，觸診起來較硬但並無壓痛，成功切除後，病理證實為一罕見之耳郭部多形性腺瘤的病例。耳郭部位之多形性腺瘤一般為良性，且大多是源於皮膚之汗腺或皮脂腺，臨床症狀通常在耳郭部有一緩慢生長之無痛性腫塊，治療上應採局部且足夠的外科切除，以避免復發。因病例罕見，特提出報告。

An 82-year-old man presented with a four month history of a painless, slow-growing mass over the left auricle. Physical examination revealed a well-defined, elastic, firm, peanut-sized mass without tenderness over the helix of his left auricle. The mass was excised and tissue pathology diagnosed a pleomorphic adenoma of the auricle. Pleomorphic adenomas are often derived from the major or minor salivary gland, with rare cases occurring externally on the ear. Most patients with pleomorphic adenomas affecting the external ear have the tumor located in the external auditory canal, indeed, only four cases of pleomorphic adenoma of the auricle have been reported in the literature to date. The patient typically presents with a painless slow-growing mass over the auricle and treatment usually comprises surgical excision. Owing to the likelihood of pleomorphic adenoma recurrence, surgical excision should encompass the tumor, the underlying perichondrium, and sometimes even the cartilage.
