[Multiple eccrine hidrocystomas in Parkinson disease].

We describe clinically and histologically typical eccrine hidrocystomas on the eyelids and forehead of a 60-year-old woman which were successfully treated with topical atropine. Concomitantly the patient had long-standing Parkinson's disease with typical facial seborrhea and hyperhidrosis. In this report, we review the literature about eccrine hidrocystomas and discuss the question of a causal relationship with Parkinson's disease in our patient.
