Cutaneous horn is conical shape of compact keratin that resembles a miniature animal horn. Though morphologically similar to horns in animals they are histologically very different from them. It is a circumscribed, conical, hyperkeratotic dense protrusion with epithelial cornification above the skin surface in response to a wide range of underlying benign and malignant pathological changes. Though benign, a cutaneous horn holds the potential to be premalignant or malignant. In India till now six cases has been reported with cutaneous horn at various unusual sites. We report a unique case of 52-year-old woman with a giant cutaneous horn at left oral commissure with underlying verrucous carcinoma of left buccal mucosa which is a very rare location for such lesion. Considering its malignant potential, adequate therapy requires wide excision with a tumour-free margin of at least 1 cm, particularly in the facial region where the incidence of malignancy is higher.
皮肤角是一种致密角蛋白构成的圆锥形结构，形似微型动物角。尽管在形态上与动物的角相似，但它们在组织学上与动物角有很大不同。它是一种局限性的、圆锥形的、角化过度的致密突出物，是皮肤表面上皮角化对多种潜在的良性和恶性病理变化的反应。虽然皮肤角是良性的，但有恶变或恶性的可能。在印度，迄今已报道了6例皮肤角出现在各种不寻常部位的病例。我们报告了一例独特的病例，一名52岁女性，左侧口角处有一个巨大的皮肤角，其下方为左侧颊黏膜疣状癌，这是该病变非常罕见的部位。鉴于其恶变潜能，充分的治疗需要进行广泛切除，切缘至少有1 cm无肿瘤组织，特别是在恶性发生率较高的面部区域。
