OSTEOSCLEROTIC METASTASIS CAUSED BY EPIPHARYNX TUMOR IN PARANASAL SINUS

Abstract

Metastasis or infiltration of epipharynx carcinoma frequently causes osteolytic lesion. There are reports that these symptoms may exhibit osteosclerotic lesion, but this isconsidered to be rare, clinically. From this aspect, infiltration or metastasis of epipharynx carcinoma may not be likely when osteoma or fibrous dysplasia on the head and face are suspected. We report here a case with epipharynx carcinoma exhibiting osteosclerotic lesions in the sphenoidal and posterior ethmoidal sinuses, including some considerations from the literature pertaining to details of the case.
