Intraorbital apocrine hidrocystoma.

A 33-year-old man reported an 18 months history of a progressive right eyelid swelling, a sensation of eye pain and headaches. He noted a visual discomfort. Physical examination showed right eyelid edema, without skin lesion. The patient's acuity was unchanged from the baseline; neither exophthalmia nor deficit in the visual field was noted. Magnetic resonance image showed an intraorbital, extraconal cystic lesion. Histopathologic examination revealed apocrine hidrocystoma.
