Irritated lentigo or seborrheic keratosis
References
一位56岁的男性来到我们的整形诊所，因为他发现自己的左耳上有一个无痛肿块，该肿块已经缓慢生长了大约一年。检查时，我们发现他的左耳有一个约 2. 5 × 2. 0 厘米大小的深色肿块，一直延伸到耳道内。附近没有肿大的淋巴结。为了检查它是否癌变，我们采集了肿块的一小部分样本进行测试。结果显示是 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.

如果怀疑恶性肿瘤，则需要进行活检。
