[Malignant teratocarcinosarcoma of the nose and paranasal sinuses].

Malignant teratocarcinosarcoma of the nasal cavity and the paranasal sinuses is a rare and invasive tumor. It is characterized by a mixture of mesenchymal and epithelial components, with cellular elements of a fetal nature. We describe in detail the first and only case in Israel of a patient with such a tumor. Only 40-50 such cases have been described in the medical literature. We have also reviewed the existing literature dealing with malignant teratocarcinosarcoma.
