Rosacea is a chronic facial dermatosis considered to affect primarily white patients with light phototype skin, and is poorly documented in black patients. The aim of this study was to document the clinical features of rosacea in patients with phototypes V and VI. An 8-year retrospective chart review of patients with a clinical and histological diagnosis of rosacea or acne rosacea was undertaken. Of 6700 patients, 15 (0.2%) had rosacea. All were of African descent with skin phototype V or VI. Mean age was 47 years, and female : male ratio was 14 : 1. Of the 15 patients, 5 (33%) were positive for human immunodeficiency virus; 5 (33%) had used topical steroids to treat the roseacea; 6 (40%) had phototype V and presented with erythema, telangiectasia and erythematous papules, while 9 (60%) had phototype VI skin and presented with skin-coloured papules; and 10 (67%) had histology showing granulomatous rosacea, while 5 (33%) declined a facial skin biopsy. A high index of suspicion is required to diagnose rosacea in black patients as the classic signs of erythema and telangiectasia are difficult to discern.
酒渣鼻是一种慢性面部皮肤病，据认为主要影响浅色皮肤的白种人，而在黑人患者中记录较少。本研究旨在描述 V 型和 VI 型皮肤光型患者酒渣鼻的临床特征。对临床和组织学诊断为酒渣鼻或痤疮酒渣鼻的患者进行了 8 年的回顾性图表审查。在 6700 名患者中，有 15 名（0.2%）患有酒渣鼻。所有患者均为非洲裔，皮肤光型为 V 型或 VI 型。平均年龄为 47 岁，女性与男性比例为 14：1。在这 15 名患者中，5 名（33%）艾滋病毒检测呈阳性；5 名（33%）曾使用过外用类固醇治疗酒渣鼻；6 名（40%）为 V 型皮肤，表现为红斑、毛细血管扩张和红斑丘疹，而 9 名（60%）为 VI 型皮肤，表现为肤色丘疹；10 名（67%）的组织学显示肉芽肿性酒渣鼻，而 5 名（33%）拒绝进行面部皮肤活检。在黑人患者中，需要高度怀疑才能诊断酒渣鼻，因为红斑和毛细血管扩张的典型体征难以识别。
