A cystic lesion of the eyelid margin in a 37-year-old man was diagnosed clinically as an apocrine hidrocystoma, a common lesion in that location. Histopathologic examination confirmed the presence of a hidrocystoma but also disclosed an extensive proliferation of bland epithelial cells arising from the inner layer of the cyst. The authors further characterized this unique occurrence on the spectrum of Moll gland eyelid tumors by immunohistochemical analysis.
The authors report an exceptional case of a benign epithelial proliferation arising from the lining of an apocrine hidrocystoma.
