Juxta-clavicular beaded lines typical arise at puberty as an asymptomatic, linear papular eruption involving the neck and supraclavicular areas. This entity appears to be more common in blacks than caucasians, and a female predominance has been noted. Microscopically, the papules noted clinically appear secondary to sebaceous gland hyperplasia, which is particularly prominent in the immediate subepidermal zone. Mild papillated epidermal hyperplasia may be observed. Whereas many regard this entity as an anatomic variant of normal, it may be confused clinically and histologically with a number of pathologic processes. A case of juxtaclavicular beaded lines in a 14-year-old caucasian girl is presented.
锁骨旁串珠状线通常在青春期出现，是一种累及颈部和锁骨上区域的无症状线性丘疹性皮疹。这种情况在黑人中似乎比白种人更常见，并且已注意到女性居多。显微镜下，临床上所见的丘疹继发于皮脂腺增生，这在紧邻表皮下区域尤为突出。可观察到轻度乳头瘤样表皮增生。尽管许多人将此视为正常的解剖变异，但它在临床和组织学上可能与一些病理过程相混淆。本文报告一例14岁白种女孩的锁骨旁串珠状线病例。
