title: Endodermal sinus tumor of the maxillary sinus: a case report.
abstract: Endodermal sinus tumor is an uncommon malignant germ cell tumor that occurs in both gonadal and extragonadal tissues. Endodermal sinus tumors of the head and neck, exclusive of the central nervous system, are rare. We report a case of endodermal sinus tumor arising from the maxillary sinus in a 4-year-old boy. Combined treatment with radiation therapy and chemotherapy resulted in complete tumor regression.
