The patient, 16 years old male, complained of nasal obstruction. He had suffered from left nasal obstruction for 3 years. He had been performed a radical operation of sinusitis one year before. But he did not recover from nasal obstruction after the operation and suffered from mucous secretions. There was no tendency of nasal bleeding. there was a tumor in the rear of the left nasal chamber and in the left nasopharnyx, mucous secretions in the nasal/chamber.
The color of the tumor was rosy like mucous membrane, the surface was flat, and the consistency was cartilaginous.
The tumor was exposed by the palate method and exfoliated under the periosteum. It was so trong that the authors failed to remove it with the heated snare, and only succeeded with the electric knife.
The tumor filled the left nasopharynx, seemed to grow from the under plate of the sphenoid bone and invaded the sphenoid sinus.
It was histologically hard fibroma with hyaline degeneration and regressive tendency. But fatty degeneration, calcification, and ossification were not observable.
