A cutaneous horn is a common clinical entity which usually presents as a cutaneous lesion. Because of its subtle nature, patients usually tend to present late unless the lesion is big or complications develop. Because of its resemblance to animal horn, it has been given the term "horn." Cutaneous horn seems to have a remarkable history. Though cutaneous horn is benign most of the times, chances of malignancy (20-25%) should be kept in mind. Old age, giant cutaneous horn carries more chances of transformation into malignancy like in our case. Thus, early diagnosis and treatment is required in all cases. . We report a case of a 74-year-old farmer with a cutaneous projection measuring ∼8 × 5 × 3 cm over the medial surface of the right pinna for 1 year. It started as a small projection which was progressively enlarging. The primary reason behind him presenting to us was cosmetic reason since it resembled an animal horn. The projection was not associated with pain or similar lesions anywhere else in body. Understanding the malignancy risks and the cosmetic benefits, he was planned for excision biopsy of the horn. He had no systemic signs of malignancy. Histopathological reports were consistent with malignancy.
Cutaneous horns are usually benign lesions and mostly found in the head and neck region. Because of the chances of malignancy, cutaneous horns should undergo surgical removal and biopsy for early and definitive diagnosis and management.
皮肤角是一种常见的临床病症，通常表现为皮肤病变。由于其性质隐匿，除非病变较大或出现并发症，否则患者通常就诊较晚。因其形似动物的角，故而得名“角”。皮肤角似乎有着显著的病史。尽管皮肤角多数情况下是良性的，但应牢记其有恶变的可能（20% - 25%）。老年患者、巨大皮肤角如我们病例中的情况，发生恶变的几率更高。因此，所有病例均需早期诊断和治疗。我们报告一例74岁农民，其右耳廓内侧面有一个大小约为8×5×3厘米的皮肤突起，已存在1年。起初是一个小突起，随后逐渐增大。他前来就诊的主要原因是外观问题，因为它看起来像动物的角。该突起不伴有疼痛，身体其他部位也无类似病变。考虑到恶变风险和外观改善，计划对其进行角的切除活检。他没有恶性肿瘤的全身症状。组织病理学报告显示为恶性。
皮肤角通常是良性病变，大多见于头颈部区域。鉴于有恶变的可能，皮肤角应接受手术切除并进行活检，以便早期明确诊断和治疗。
