Abstract
A case of calcifying epithelioma in the submandibular region, caused by traumatic injury, is prese nted. A 56-year-old man was referred to our department about one month after bruising his right submandibular region with his stick. The lesion with subcutaneous induration was swollen and produced oppressive pain. We were confident that the lesion was a tumor, which was excised. Histopathologically, it was composed of nests or masses of shadow cells and basophilic cells.
Immunohistochemical analysis showed a positive reaction in shadow cells. The histopathological diagnosis was calcifying epithelioma.
