Abstract:
We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.
