Clear cell odontogenic carcinoma with lymph node metastasis.
Clear cell odontogenic tumors are rare. Review of the literature showed 9 cases with a prominent clear cell component. These lesions have exhibited an aggressive behavior characterized by an infiltrative local growth pattern, recurrence, or metastases. We report a case of an odontogenic tumor that exhibited a biphasic pattern and was characterized by lymph node involvement identical histologically to the primary tumor. We conclude that the presence of a clear cell component in an ameloblastomatous tumor should be viewed as a sign of de-differentiation, and that a malignancy with or without metastases should be considered and ruled out in such cases.
