2023年7月28日 · 疣（Warts）是由人類乳頭瘤病毒（HPV）感染所引致，現今已發現超過150種HPV，不同類型的HPV會引致不同種類的疣。 患者皮膚會出現啡黃色或肉色突起的顆粒或硬塊。 疣可以出現在身體任何位置，常見的位置包括面部、頸部、手或腳。 由於疣具有傳染性，數量可以隨時間增加，最初可能只有幾粒，後來演變成數十至數百粒不等。 皮膚疣成因. HPV病毒喜歡在温暖潮濕的環境滋長，能透過接觸患者的皮膚患處，或接觸帶有HPV病毒的物件而傳播，免疫力較弱人士或皮膚有傷口者容易受到感染。 病毒可以在家庭成員之間交叉感染，或透過共用個人物品而傳播，例如共用化妝粉餅、化妝粉撲、化妝掃、睫毛夾、毛巾、剃鬚刀、枕頭床單、赤腳於公共泳池或健身室行走等。

A cutaneous wart is also called a ...
Warts are particularly common in: 1. School-aged children, however they may occur at any age 2. Dermatitis, due to a defective skin barrier 3. People with drug-induced immunosuppression such as with long-term azathioprine or ciclosporin use, or have human immunodeficiency virus (HIV) infection.
Warts are due to infection by the human papillomavirus (HPV), a double-stranded DNA virus. There are more than 150 known HPV types, only some of which infect the skin, giving rise to a variety of clinical presentations. Infection begins in the basal layer of the epidermis, causing proliferation of the keratinocytes (skin cells) and hyperkeratosis, ...

疣 (Viral Warts)屬於過濾性病毒的感染，病源是一種名為人類乳頭瘤病毒 (Human Papilloma Virus﹐簡稱HPV)﹐能透過人與人的接觸而傳染開去。 HPV的種類非常多﹐當中引發「疣」的只屬傳染性皮膚病的一種﹐跟性接觸感染的性病無甚關係。 常見位置: 面、頸、手背、四肢. 扁平疣 (Plane Warts)是其中一種最為常見 的疣。 這類過濾性病毒非常普遍﹐大量存在於四周環境中﹔當皮膚表面有傷口﹐加上免疫系統較弱或本身體質較差﹐便會受此微生病毒感染。 患有扁平疣帶來的影響﹕. 一旦感染了﹐皮膚表面形成肉色或淺啡色、質地粗糙的小粒﹐邊界清晰。 一般扁平疣雖然對健康無大影響﹐但會具傳染性。 若不處理﹐扁平疣會蔓延至非常多的數量﹐影響個人儀容。
1. 尋常疣（common warts）：HPV 2、4、27、29 血清型為主。 外觀為往外凸起的棕色、粗糙角化的顆粒或斑塊。 常出現於手部、指甲周圍或四肢。 2. 足部疣（plantar warts）：HPV 1 血清型為主。 出現在腳底，好發於孩童和青少年。 比尋常疣來得厚皮，由於在足底不易提早發現，當病灶長太大時可能會疼痛紅腫，造成行走不適。 3. 扁平疣（flat warts）：HPV 3、10血清型為主。 突起面與上述的疣不同，較平滑、扁平、粉膚色，常出現在前額、臉部、前臂和小腿，很常被忽略而延誤治療或誤以為是老人斑。 4. 生殖器疣（genital wart or condyloma acumilatum）：HPV 6、11 血清型為主。
