Irritated lentigo or seborrheic keratosis

一位56歲的男子來到我們的整形診所，因為他發現自己的左耳上有一個無痛腫塊，腫塊已經緩慢生長了大約一年。檢查時，我們發現他的左耳有一個約 2. 5 × 2. 0 厘米大小的深色腫塊，一直延伸到耳道內。附近沒有腫大的淋巴結。為了檢查它是否癌變，我們採集了腫塊的一小部分樣本進行測試。結果顯示是 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.
