Seborrheic keratosis - 脂溢性角化病
relevance score : -100.0%
ReferencesSeborrheic keratoses（脂溢性角化病）常见于成年人和老年人，是一种良性的皮肤增生，通常无害且不需要治疗。激光疗法是治疗 Seborrheic keratoses 的非手术选择，主要包括两类：ablative（例如 YAG 和 CO₂ 激光）和 non‑ablative（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.

最常见的良性炎症性病变是 chalazion（麦粒肿）和 pyogenic granuloma（化脓性肉芽肿）。感染可导致多种疾病，如 verruca vulgaris（寻常疣）、molluscum contagiosum（传染性软疣）和 hordeolum（麦粒肿）。良性肿瘤性病变可能包括 squamous cell papilloma（鳞状细胞乳头状瘤）、epidermal inclusion cyst（表皮囊肿）、dermoid/epidermoid cyst（皮样/表皮囊肿）、acquired melanocytic nevus（获得性黑色素痣）、seborrheic keratosis（脂溢性角化病）、hidrocystoma（汗腺囊肿）、cyst of Zeiss（Zeiss 囊肿）和 xanthelasma（黄瘤）。
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，触感平坦或略微隆起，外观类似愈合伤口的痂，大小从极小到超过 2.5 厘米（1 英寸）不等。
○ 诊断
深色色素病变常与结节性黑色素瘤难以区分。此外，即使通过皮肤镜检查，面部皮肤上的轻度脂溢性角化病也很难与恶性雀斑样痣区分。临床上，表皮痣的外观与脂溢性角化病相似，表皮痣通常在出生时或临近出生时出现。尖锐湿疣和普通疣在临床表现上可与脂溢性角化病相似；在阴茎和生殖器皮肤上，尖锐湿疣与脂溢性角化病也难以辨别。
○ 流行病学
脂溢性角化病是最常见的良性皮肤肿瘤。在大型队列研究中，所有（100%）50 岁以上的受试者至少出现一种脂溢性角化病。该病通常在中年出现，但在年轻人中也常见；约 12% 的 15–25 岁人群中可见。
○ 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。
