Basal cell epithelioma arising from epidermoid cyst.
BACKGROUND
Basal cell epithelioma is a tumor arising from a pluripotential cell found within the basal cell layer of the epidermis or various appendageal structures.


OBJECTIVE
We report two cases of basal cell epithelioma arising from the wall of an epidermoid cyst.


RESULTS
Review of our files produced two cases of basal cell epithelioma arising from a cyst wall.


CONCLUSIONS
Basal cell epithelioma arising from the wall of an epidermoid cyst is rare. Examination of all cysts removed surgically is important as not to overlook this possibility and to allow close follow-up for potential recurrence.
