Verruca plana - 扁平疣https://en.wikipedia.org/wiki/Flat_wart
扁平疣 (Verruca plana) 為紅棕色或肉色、稍微隆起、表面平坦且界限清楚的丘疹,直徑 2 至 5 mm。仔細觀察可見病變表面不規則。大多數病例出現在臉部。

治療 – 非處方藥
避免過度清潔或觸摸病灶,因摩擦可能使扁平疣藉小傷口擴散。水楊酸製劑僅能小心塗抹於患處,避免在病灶周圍使用過多酸性物質。

References Different skin wart types, different human papillomavirus types? A narrative review 38126099
皮膚疣是由人類乳突病毒(HPV)引起的。許多研究調查了不同類型的疣(如尋常疣、蹠疣和扁平疣)中發現的 HPV 類型。研究發現了多種 HPV 類型,但通常尚不清楚哪些是致病原因。本文綜述了檢測疣中 HPV 的新方法,包括樣本採集方式、使用的檢測技術以及病毒載量的估算。我們亦回顧了尋常疣、足底疣與扁平疣的相關研究,並簡要討論了不同 HPV 類型在疣組織樣本中的分布情形。
Skin warts are caused by human papillomaviruses (HPV). Many studies have looked into the types of HPV found in different warts like common, plantar, and flat warts. They've found various HPV types, but often it's not clear if they're the cause. This review paper discusses new methods for testing HPV in warts, including how to take samples, which tests to use, and estimating the amount of virus in cells. We also reviewed studies on HPV in common, plantar, and flat warts and briefly talked about how different HPV types show up in tissue samples of warts.
