Multiple eccrine hidrocystomas: report of two cases treated unsuccessfully with atropine ointment.

ABSTRACT

Eccrine hidrocystomas are rare, benign, cystic lesions with a lining that resembles that of the eccrine sweat gland and may be solitary or multiple. Multiple eccrine hidrocystomas occur predominantly on the face as asymptomatic, skin-colored to bluish lesions associated with a chronic course and seasonal variability. Treatment of multiple lesions on the face is challenging. Efficacy with atropine ointment is variable. Botulinum toxin and pulsed dye laser are reported to be beneficial. Two cases of multiple eccrine hidrocystomas are reported who showed no response to 1% atropine ointment.
