relevance score : -100.0%
ReferencesSeborrheic keratoses 常见于成年人和老年人，是一种良性的皮肤增生，通常无需治疗。激光疗法是治疗 Seborrheic keratoses 的非手术选项，可采用两种类型的激光：消融性（例如 YAG 激光和 CO2 激光）和非消融性（例如 755 nm Alexandrite 激光）。
Seborrheic keratoses are epidermal skin tumors that commonly present in adult and elderly patients. They are benign skin lesions and often do not require treatment. Laser therapy is non-surgical option for patients in the treatment of seborrheic keratosis. Ablative laser therapy includes (YAG and CO2 lasers), and non-ablative lasers (755 nm alexandrite laser) have been utilized for this purpose.

最常见的良性炎症病变是 chalazion 和 pyogenic granuloma。感染可导致各种疾病（verruca vulgaris、molluscum contagiosum 和 hordeolum）。良性肿瘤病变可能包括 squamous cell papilloma、epidermal inclusion cyst、dermoid/epidermoid cyst、acquired melanocytic nevus、seborrheic keratosis、hidrocystoma、cyst of Zeiss 和 xanthelasma。
The most common benign inflammatory lesions include chalazion and pyogenic granuloma. Infectious lesions include verruca vulgaris, molluscum contagiosum, and hordeolum. Benign neoplastic lesions include squamous cell papilloma, epidermal inclusion cyst, dermoid/epidermoid cyst, acquired melanocytic nevus, seborrheic keratosis, hidrocystoma, cyst of Zeiss, and xanthelasma.

脂溢性角化病的病变颜色多样，范围从浅棕褐色到黑色。它们呈圆形或椭圆形，触感平坦或略有隆起，外观类似愈合伤口的痂。大小从极小到超过 2.5 厘米（约 1 英寸）不等。
○ 诊断
深色素病变常与结节性黑色素瘤难以区分。即使通过皮肤镜检查，面部的薄型脂溢性角化病也容易与恶性雀斑样痣混淆。临床上，表皮痣的外观与脂溢性角化病相似，且表皮痣通常在出生或出生后不久出现。尖锐湿疣和普通疣在外观上也可与脂溢性角化病相似，尤其在阴茎和生殖器皮肤上，二者难以辨别。
○ 流行病学
脂溢性角化病是最常见的良性皮肤肿瘤。大规模队列研究显示，100% 的 50 岁以上人群至少出现一种脂溢性角化病。虽然常见于中年人，但在年轻人中亦不罕见，例如在 15–25 岁人群中有约 12% 出现。
○ 治疗
通常可采用激光手术去除病变，且不易留下明显的色素沉着。
