Tenascin-C, GLUT-1, and syndecan-2 expression in juvenile nasopharyngeal angiofibroma: correlations to vessel density and tumor stage.

BACKGROUND Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular tumor with some characteristics resembling those of vascular malformations. The significance of different growth and angiogenesis promoting factors for the etiology of JNA remains unsolved. METHODS We analyzed the immunoexpressions of glucose transporter 1 (GLUT-1), tenascin-C (TNC… (More)
