ReferencesSeborrheic keratoses 是經常出現在成年人和老年人身上的皮膚增生。它們是無害的，通常不需要治療。雷射療法是治療 Seborrheic keratoses 的非手術選擇。可使用兩種類型的雷射：ablative（例如 YAG 與 CO₂ 雷射）和 non‑ablative（例如 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.

最常見的良性發炎病灶是 chalazion 和 pyogenic granuloma。感染可導致多種疾病（verruca vulgaris、molluscum contagiosum、hordeolum）。良性腫瘤病變可能包括 squamous cell papilloma、epidermal inclusion cyst、dermoid/epidermoid cyst、acquired melanocytic nevus、seborrheic keratosis、hidrocystoma、cyst of Zeiss 以及 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.

脂漏性角化症的病灶呈現多種顏色，從淺棕褐色到黑色不等。它們多為圓形或橢圓形，觸感平坦或略為隆起，外觀類似癒合傷口的痂。尺寸範圍從極小到超過 2.5 厘米（1 英吋）寬。
○ 診斷
深色的色素病灶常與結節性黑色素瘤難以區分。即使使用皮膚鏡檢查，臉部皮膚上的薄型脂漏性角化症仍可能與惡性雀斑樣痣混淆。臨床上，表皮痣的外觀與脂漏性角化症相似，且表皮痣通常於出生時或接近出生時出現。尖銳濕疣與普通疣在臨床表現上也與脂漏性角化症相似，尤其在陰莖及生殖器皮膚上，兩者更難區分。
○ 流行病學
脂漏性角化症是最常見的良性皮膚腫瘤。大型隊列研究顯示，所有 50 歲以上的受試者至少有一個脂漏性角化症。此病通常於中年發病，但在年輕族群中亦相當常見；約 12% 的 15 至 25 歲者會出現此情況。
○ 治療
一般而言，可透過雷射手術去除病變，且不會留下色素沉著。
