References一位56歲的男子來到我們的整形診所，因為他發現左耳上有一個無痛腫塊，且已緩慢生長約一年。檢查時，我們發現左耳有一個約 2.5 × 2.0 公分大小的深色腫塊，延伸至耳道內，附近未見腫大的淋巴結。為了確認是否有惡性變化，我們取了腫塊的一小部分進行檢測，結果顯示為 seborrheic keratosis。
A 56-year-old man presented to our outpatient plastic surgery clinic with a 1-year history of a slow-growing, painless mass in his left auricle. In the physical examination, we observed a 2.5 × 2.0 cm blackish papillomatous lesion within the left cavum concha, extending into the external auditory canal. There was no palpable enlargement of the regional lymph nodes. An incisional biopsy was performed to rule out a malignant skin tumor, and the histopathological examination revealed seborrheic keratosis.
