ReferencesCutaneous horn 基本上是一种可见的增生物，肉眼观察时呈白色或黄色，形似动物角。目前普遍认为，这些角的出现是对不同皮肤问题的反应——有些是良性的，有些可能会恶变为癌症。Actinic keratoses 是最常见的良性（非癌性）原因，而 squamous cell carcinoma (SCC) 则是最常见的恶性（癌性）原因。
A cutaneous horn is usually evident upon physical examination and can be described as a white or yellow exophytic protrusion in the shape of an animal horn. Cutaneous horns are now widely accepted as a reactive cutaneous growth caused by a variety of benign, premalignant, or malignant primary processes. Actinic keratoses are the most common premalignant primary cause of cutaneous horn, while squamous cell carcinoma (SCC) is the most common malignant cause.

Cutaneous horn 是一种致密的圆锥形生长物，皮肤增厚，外观常类似动物的角。该术语描述的是硬化皮肤细胞的异常堆积，而非特指某一种疾病。Cutaneous horns 可能伴随各种良性、癌前期或恶性皮肤病出现。一个关键问题是区分增厚的晒伤皮肤斑块与潜在的恶性生长（如鳞状细胞癌）。另一个常见原因是角化棘皮瘤，它表现为凸起的指甲样肿瘤。治疗通常包括切除角状组织，并在显微镜下检查以确定是否存在癌变。
Cutaneous horn is a dense, cone-shaped growth with thickened skin, often resembling an animal's horn. It's a term describing an unusual buildup of hardened skin cells, rather than a specific disease. Cutaneous horns can develop alongside various benign, pre-cancerous, or cancerous skin conditions. A key concern is distinguishing between a thickened sun-damaged skin spot and a potentially cancerous growth like squamous cell carcinoma. Another culprit is keratoacanthoma, which presents as a raised, nail-like tumor. Treatment typically involves removing the horn and examining it under a microscope to check for cancer.

约 20% 的病例伴有恶性肿瘤，其中鳞状细胞癌最为常见。若病变位于阴茎，鳞状细胞癌的发生率可达 37%。
