Two Cases of Angiofibroma

Two cases of angiofibroma that occurred in different areas are reported. Case one: A 55-year-old woman who complained of repeated epistaxis and nasal obstruction on the right side. Magnetic resonance imaging (MRI) examination showed a homogeneous solid mass without flow-void pattern occupying the right nasal cavity. Case two: A 20-year-old man complained of persistent epistaxis. MRI examination showed a large solid mass with flow-void pattern originating from rich capillary proliferation in the nasopharynx. The tumor was removed incompletely because of massive bleeding. Although the histopathological diagnosis was angiofibroma in both cases, there were some differences between them. The tumor in case one was composed of loose fibro-proliferative tissue with capillary and myxoid degeneration, whereas that in case two was composed of thick proliferation of a fibroblasts and capillaies. It seems that differences in imaging and clinical findings reflected the differences in histological findings.
