Trichoadenoma of the eyelid.
OBJECTIVE
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.


CONCLUSIONS
Trichoadenoma, a rare, benign, cutaneous tumor that usually occurs on the face, can develop on the eyelid and simulate a basal cell carcinoma.
