Abstract：
Description Porokeratosis was first described in 1893. It is a relatively rare disorder with over 9 subtypes. Lesions are clinically characterized as well-demarcated, erythematous papules (raised, <1 cm) or plaques (raised, >1 cm), with an atrophic center, and raised scaly border. Porokeratosis is an important diagnosis to identify because it may undergo malignant transformation and mimics many commonly encountered diagnoses. These commonly mimicked diagnoses include squamous cell carcinoma, tinea corporis, nummular dermatitis, and psoriasis vulgaris, to name a few. The clinical images in this review focus on identifying porokeratosis along the full spectrum of skin tones.
摘要：
描述角化病于1893年首次被描述。这是一种相对罕见的疾病，有9种以上的亚型。病变的临床特征是界限分明的，红斑丘疹（凸起，<1厘米）或斑块（凸起，>1厘米），有一个萎缩的中心，和凸起的鳞状边界。角化病是一种重要的诊断，因为它可能会发生恶性转化并模仿许多常见的诊断。这些通常模拟的诊断包括鳞状细胞癌，体癣,钱币状皮炎,和寻常型牛皮癣,仅举几例。这篇综述中的临床图像集中在识别整个肤色范围内的孔角化病。
