Eccrine hidrocystoma of the eyelid

Aim To report on the clinical features of eccrine hidrocystoma involving the eyelid. Methods Data on a series of consecutive patients with histopathologically confirmed diagnosis were reviewed. Results Among 34 patients, 69 tumours were identified. The mean age at diagnosis was 59 years ( range 39 - 91 years). The majority (71%) of patients had only a single tumour. The tumours appeared as a small ( median size = 1 mm) clear cystic lesion with 87% located near the eyelid margin. Conclusions The eccrine hidrocystoma is a benign small cystic tumour that characteristically occurs close to but does not involve the eyelid margin.
