Cutaneous horn - 皮角
由於皮膚癌（例如鱗狀細胞癌）經常存在，因此需要進行活檢。

Cutaneous horn 基本上是一種可見的生長物，當您觀察它時，它看起來像白色或黃色的動物角。現在人們普遍認為，這些角的出現是對不同皮膚問題的反應——有些是良性的，有些可能會變成癌症。 Actinic keratoses 是最常見的非癌症原因，而 squamous cell carcinoma (SCC) 是最常見的癌症原因。
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 是一種緻密的圓錐形生長物，皮膚增厚，通常類似於動物的角。這個術語描述的是硬化皮膚細胞的異常堆積，而不是特定的疾病。 Cutaneous horns 可能與各種良性、癌症前期或癌性皮膚病一起發展。一個關鍵問題是區分增厚的曬傷皮膚斑點和潛在的癌性生長（如鱗狀細胞癌）。另一個罪魁禍首是角化棘皮瘤，它表現為凸起的指甲狀腫瘤。治療通常包括切除角並在顯微鏡下檢查以檢查是否有癌症。
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.

高達 20% 的病例存在惡性腫瘤，其中鱗狀細胞癌是最常見的類型。當病灶出現在陰莖上時，鱗狀細胞癌的發生率為 37%。
