[Multilocular eyelid hidrocystoma: an anatomical and clinical observation].

A cystic cutaneous mass was observed on the lateral canthus of the left eyelid in a 25-year-old woman, 2 years after being operated on for a lesion that had existed in the same area several years before, but the patient could not identify its nature. The present mass appeared as a well-circumscribed bluish cystic lesion. A surgical resection was performed; pathological analysis disclosed a cystic sweat tumor composed of several contiguous cysts. One year of follow-up has revealed no complications.
