日光性雀斑样痣、脂溢性角化病及扁平苔藓样角化病皮肤镜特征专家共识

【摘要】 日光性雀斑样痣、脂溢性角化病及扁平苔藓样角化病是常见的良性表皮增生性疾病，其皮肤镜特征对于明确诊断、与其他皮肤肿瘤相鉴别、避免不必要的活检和手术以及动态监测皮损变化等都有一定帮助。本共识对这3种疾病的皮肤镜特征进行了总结。日光性雀斑样痣的皮肤镜特征主要为皮损边界清晰、虫蚀状边缘、模糊的色素网、指纹模式、棕色均质模式、假性网络。脂溢性角化病的皮肤镜特征主要为皮损边界清晰、粟粒样囊肿、粉刺样开口、脑回状模式、发夹样血管、摇晃试验中皮损整体移动。扁平苔藓样角化病的皮肤镜特征主要为胡椒粉样或颗粒模式以及周围可见日光性雀斑样痣、脂溢性角化病或光线性角化病的皮肤镜特征。

Dermoscopic features of solar lentigo,seborrheic keratosis and lichen planus-like keratosis: an expert consensus statement#br#

【Abstract】 Solar lentigo, seborrheic keratosis, and lichen planus-like keratosis are common benign epidermal proliferative diseases. To recognized their dermoscopic characteristics is helpful in many clinical aspects, such as making clear diagnoses, differentiating from other skin neoplasms, avoiding unnecessary biopsies or surgeries, and real-time monitoring of lesion changes. This consensus summarizes the dermoscopic characteristics of the 3 diseases. The dermoscopic features of solar lentigo include sharply demarcated borders, moth-eaten borders, faint pigment network, fingerprint-like areas, homogeneous brown pattern, pseudonetwork. The dermoscopic features of seborrheic keratosis are sharply demarcated borders, milia-like cysts, comedo-like openings, cerebriform pattern, hairpin blood vessels, moving en bloc in the wobble test. The dermoscopic features of lichen planus-like keratosis are pepper-like dots/granules, which may be surrounded by features of solar lentigo, seborrheic keratosis or actinic keratosis.
