Junctional nevi are traditionally associated with children and younger patients. We noticed that these lesions are also often found in elderly patients.
We sought to determine if junctional nevi are found in all age groups.
All biopsy reports for junctional nevi for the year 2001 at the Penn State Milton S. Hershey Medical Center were reviewed. Age of patients and locations for these nevi were noted and the results analyzed.
The age distribution of junctional nevi shows that these lesions occur with similar frequency in the young and in the elderly. Lesions were more frequent in non-sun-exposed skin.
The age distribution between biopsied nevi and nevi not biopsied may be different. Sampling error may also lead to mis-classification of nevi.
Junctional nevi are common in all age groups.
传统上，交界痣与儿童及年轻患者相关。我们注意到这些病变在老年患者中也经常被发现。
我们试图确定交界痣是否在所有年龄组中都有发现。
回顾了宾夕法尼亚州立大学米尔顿·S·赫尔希医疗中心2001年所有交界痣的活检报告。记录患者年龄及这些痣的位置，并对结果进行分析。
交界痣的年龄分布表明，这些病变在年轻人和老年人中出现的频率相似。病变在非暴露于阳光的皮肤中更为常见。
活检痣与未活检痣之间的年龄分布可能不同。抽样误差也可能导致痣的分类错误。
交界痣在所有年龄组中都很常见。
