A Case Report of Neurilemmoma of the Larynx

Neurilemmoma of the larynx is an uncommon lesion. In Japan, the first case was reported in 1948, and since then, only 59 cases have been reported to our knowledge. We recently treated a 22-year-old female with a neurilemmoma of the larynx. She had suffered from hoarseness for 5 years. The lesion was located in the right false cord and vocal cord, and was found to be a submucosal tumor. It was resected by laryngofissure, resulting in improved phonation, and no recurrence has been noted in 13 months of follow up.

Salivary Duct Carcinoma; Two Case Reports.

We present two cases of salivary duct carcinoma in this paper. Both cases were middle-aged men. They were treated with total parotidectomy and postoperative radiotherapy. Both cases have been followed up for 18 and 15 months respectively with no evidence of local recurrence or distant metastasis.Sixty-six cases of salivary duct carcinoma, including ours, have been reported in the Japanese literature. We reviewed the clinical characteristics of this unusual tumor. Most cases were male (90%) and occured in the parotid gland (84%). The average age was 61 years, ranging from 36 to 91. In 44% of patients, parotid tumors are accompanied by facial nerve paralysis. Total parotidectomy or extended parotidectomy followed by radiotherapy was the most common treatment for patients with salivary duct carcinoma in the parotid gland. The prognosis was poor and the 5-year survival rate was 28%.
