ABSTRACT
Background: Apocrine hidrocystomas, also known as apocrine cystadenomas,
are bening cystic tumours derived from the secretory portion of
apocrine sweat glands.
Case report: 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.
