Pilar tumors.

We present 5 cases of pilar tumor, and we review the controversy over whether this tumor has a malignant potential. We feel the correct treatment is excision deep to galea, with a one to two cm margin of normal scalp. Presented with a pathology report of "pilar tumor" on a "shelled out" or ruptured sebaceous cyst, we feel the correct treatment is complete excision of the previous scar, going deep to the galea and taking a one to two cm margin of surrounding normal scalp.
