Cutaneous horns are hard, yellowish gray cornified skin growths. They are more common in white races and believed to be rare in Africans. There are few case reports of the lesion in African populations in the English literature.
This report documents six patients with this lesion seen over a fourteen month period. There were three males and three females, aged 22 to 62 (mean= 47).
One lesion was on the scalp, the remaining on the extremities. The underlying pathologies were squamous cell carcinoma (1), Kaposi sarcoma (1), cutaneous myxoma (1), eccrine poroma (1) and the remaining two showed only chronic inflammatory changes with subepidermal lymphocytic and macrophage cell infiltrates.
Unless cases are well documented, the perception of rarity in Africans will most likely persist. The risk of underling malignancy underscores the need for detailed evaluation and prompt management.
皮肤角是坚硬的、黄灰色的角质化皮肤肿物。它们在白种人中更为常见，而在非洲人中被认为很罕见。英文文献中关于非洲人群中该病变的病例报告很少。
本报告记录了在14个月期间见到的6例患有该病变的患者。其中有3名男性和3名女性，年龄在22至62岁之间（平均年龄 = 47岁）。
1例病变位于头皮，其余位于四肢。潜在病理情况为鳞状细胞癌（1例）、卡波西肉瘤（1例）、皮肤黏液瘤（1例）、小汗腺汗孔瘤（1例），其余2例仅显示慢性炎症改变，伴有表皮下淋巴细胞和巨噬细胞浸润。
除非病例有充分记录，否则非洲人该病罕见的观念很可能会持续存在。潜在恶性肿瘤的风险强调了详细评估和及时处理的必要性。
