Abstract
Calcifying epithelioma is a tumor originating in hair cortex cells. It tends to occur in the head and neck region.
We reported a case of rapidly growing calcifying epithelioma. The patient, a 12-yearold girl, had a bone-like hard tumor in her parotidomasseteric region. The tumor had grown rapidly for the last three months before operation. The tumor was extirpated and histological examination revealed a calcifying epithelioma. An inflammatory stimulus apparently promoted the rapid growth of this tumor. There has been no evidence of recurrence for 8 years after operation.
