Purpose:
To report the unique occurrence of a trichoadenoma of the eyelid.
Methods:
An 80-year-old woman underwent surgical resection of a lesion of the right lower eyelid that was suspected to be a basal cell carcinoma. The lesion was studied with light microscopy.
Results:
Histopathology showed a lesion in the dermis that contained keratin cysts surrounded by a proliferation of eosinophilic epidermoid cells. The findings were characteristic of a trichoadenoma.
Conclusion:
Trichoadenoma, a rare, benign, cutaneous tumor that usually occurs on the face, can develop on the eyelid and simulate a basal cell carcinoma.
