Seborrheic keratosis - 脂溢性角化病
References
Seborrheic keratoses 是经常出现在成年人和老年人身上的皮肤增生。它们是无害的，通常不需要治疗。激光疗法是治疗 seborrheic keratoses 的非手术选择。使用两种类型的激光疗法： ablative (e. G. , YAG and CO2 lasers) and non-ablative (e. G. , 755 nm alexandrite laser) 。
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, and 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, and 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呈现各种颜色，从浅棕褐色到黑色。它们呈圆形或椭圆形，感觉平坦或略微隆起，就像愈合伤口的痂一样，尺寸范围从非常小到超过 2.5 厘米（1 英寸）宽。
○ 诊断
深色色素病变很难与结节性黑色素瘤区分开来。此外，即使通过皮肤镜检查，面部皮肤上的薄脂溢性角化病也很难与恶性雀斑样痣区分开来。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。尖锐湿疣和疣在临床上类似于脂溢性角化病。在阴茎和生殖器皮肤上，尖锐湿疣和脂溢性角化病很难区分。
○ 流行病学
脂溢性角化病是最常见的良性皮肤肿瘤。在大队列研究中，100% 50 岁以上的患者至少患有一种脂溢性角化病。通常在中年发病，但在年轻患者中也很常见，例如 12% 的 15 岁至 25 岁患者中出现这种情况。
○ 治疗
一般来说，可以通过激光手术去除病变，而不会留下色素沉着过度。
