BACKGROUND
Apocrine hidrocystomas, also known as apocrine cystadenomas, are bening cystic tumours derived from the secretory portion of apocrine sweat glands.
CLINICAL CASE
A 78-year old female was referred to our division for assesment an asymptomatic translucent, well-defined cystic lesion located on the upper helix. The histological features were consistent with apocrine hidrocystoma coexisting with gouty tophi.
CONCLUSIONS
We report the second case of apocrine hydrocystoma located in the pinna, outside of ear canal and the first case of its association with gouty tophi described. It is difficult to know which lesion was first established and if the tophi may lead to ductal obstruction and subsequent cystic retention.
背景
顶泌汗腺囊瘤，也称为顶泌汗腺囊腺瘤，是源自顶泌汗腺分泌部的良性囊性肿瘤。
临床病例
一名78岁女性因评估位于耳轮上部的无症状半透明、边界清晰的囊性病变被转诊至我科。组织学特征符合顶泌汗腺囊瘤合并痛风石。
结论
我们报告了第二例位于耳廓、外耳道外的顶泌汗腺囊瘤病例，以及第一例其与痛风石相关的病例。很难确定哪个病变先出现，以及痛风石是否可能导致导管阻塞及随后的囊性潴留。
