relevance score : -100.0%
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 (e.g., YAG and CO2 lasers) 和 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.

最常見的良性發炎性病灶是 chalazion（麥粒腫）和 pyogenic granuloma（化膿性肉芽腫）。感染可引起多種疾病，如 verruca vulgaris（尋常疣）、molluscum contagiosum（傳染性軟疣）和 hordeolum（麥粒腫）。良性腫瘤性病變可能包括 squamous cell papilloma（鱗狀細胞乳頭狀瘤）、epidermal inclusion cyst（表皮囊腫）、dermoid/epidermoid cyst（皮樣/表皮囊腫）、acquired melanocytic nevus（後天性色素痣）、seborrheic keratosis（脂溢性角化病）、hidrocystoma（汗腺囊腫）、cyst of Zeiss（Zeiss 囊腫）以及 xanthelasma（黃瘤）。
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.

脂漏性角化症的病灶呈現各種顏色，從淺棕褐色到黑色。它們呈圓形或橢圓形，觸感平坦或略微隆起，像癒合傷口的痂，尺寸範圍從非常小到超過 2.5 公分（1 英寸）寬。
○ 診斷
深色素病灶很難與結節性黑色素瘤區分開來。此外，即使透過皮膚鏡檢查，臉部皮膚上的薄脂漏性角化症也很難與惡性雀斑樣痣區分。臨床上，表皮痣的外觀與脂漏性角化症相似，表皮痣通常在出生時或接近出生時出現。尖銳濕疣和疣在臨床上與脂漏性角化症相似；在陰莖和生殖器皮膚上，尖銳濕疣與脂漏性角化症亦難以區分。
○ 流行病學
脂漏性角化症是最常見的良性皮膚腫瘤。在大型隊列研究中，100% 的 50 歲以上患者至少有一種脂漏性角化症。通常在中年發病，但在年輕患者中也很常見，例如 12% 的 15 歲至 25 歲患者會出現此情況。
○ 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。
