References一位56岁男性来到我们的整形诊所，因发现左耳出现一个无痛肿块，已缓慢生长约一年。检查时，发现左耳有一约2.5×2.0厘米的深色肿块，向耳道内延伸。未触及肿大淋巴结。为排除恶性变，取肿块一小块进行病理检查，结果为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.
