Abstract:
The clinicopathological features of a rare case of juvenile angiofibroma originating from the maxillary sinus of a 13-year-old boy are reported. This tumor was composed of angiomatous and fibrous structures. The analysis of nucleolar organizer regions (NOR) of the various components of this tumor indicated that the fundamental elements were the fibroblastic cells, rather than the vascular endothelial cells.
