The Neurinom which was introduced and named by Jose Verocay in 1908 has three histological characteristics: 1) Palisadenstellung of the cell nucleus of a tumor, 2) the yellow coloration of the tumor fiber by the Van Gieson coloration, 3) typical ganglion cell, lacking the colloid cell, and embryologically said to be the ectodermal tumor which grows from Schwann's sheath.
This case, which was experienced on an outpatient of this department, was one in which the Neurinom appeared on the bottom of the oral cavity. Fortunately the whole process of this case was examined by literal observation as well as clinical observation as follows: age, sex, part of generis, symptoms, diagnosis, treatment, prognosis, etc. This case was at first diagnosed as cases up to this time, that is, to be a cuticular cyst on the bottom of the oral cavity, and only after its extraction was it found to be Nuerinom by histological research.
