A 66-year-old woman was first seen in the Department of Otorhinolaryngology of Kawasaki Medical School Hospital on June 18, 1984. She had a persistent left auricular mass (20 × 20mm), which had been growing for 40 years.
The initial operation was performed on August 8, 1984. The initial pathological report was benign schwannoma. She was asymptomatic until 1985.
In January 1986, she again noticed a left auricular mass (17 × 15mm). She came to our hospital on June 14, 1986. A second operation was performed on July 31, 1986. During the second operation, we completely resected the tumor with enough margin for safety, and a complete postauricular rotation flap was done. The second pathological report was malignant schwannoma. Since the second operation, she has been tumor free for about 3 years.
There have been only a few reports of malignant schwannoma in the head and neck region. Therefore we reviewed the cases of malignant schwannoma in the head and neck region in Japan.
