Apocrine hidrocystoma (AH) is a benign cystic proliferation of apocrine sweat glands that classically presents as a slow-growing nodule on the face, especially in the periorbital region. Histopathological evaluation is required to definitively diagnose an apocrine hidrocystoma. Previous studies have described apocrine hidrocystomas in unusual locations. However, the authors have identified only two reported cases of apocrine hidrocystoma in the postauricular region. We present a third case of a postauricular hidrocystoma in a 26-year-old woman, as well as a brief review of the dermoscopic findings of apocrine hidrocystomas in the existing literature.
顶泌汗腺囊瘤（AH）是顶泌汗腺的良性囊性增生，通常表现为面部，尤其是眶周区域的缓慢生长结节。需要进行组织病理学评估才能明确诊断为顶泌汗腺囊瘤。既往研究已描述过罕见部位的顶泌汗腺囊瘤。然而，作者仅发现两例报道的发生在后耳区域的顶泌汗腺囊瘤。我们报告了第 3 例发生在后耳区域的汗管瘤，并简要回顾了现有文献中顶泌汗腺囊瘤的皮肤镜特征。
