Laryngeal lymphoepithelial carcinoma (LEC) is a rare tumor with only 34 cases in the published literature. Epidemiologically, laryngeal LEC is extremely rare in Asian. Originally, LEC is a common type of carcinoma in nasopharynx. Laryngeal LEC resembles nasopharyngeal LEC, except that most cases of laryngeal LEC are not associated with Epstein-Barr virus. We present a case of laryngeal LEC which developed at the left false cord extending to true vocal cord, para-glottic space and pre-epiglottic space. Total laryngectomy with bilateral neck dissection was performed. LEC was reported as biopsy confirmation result. The patient underwent postoperative radiotherapy and showed no evidence of recurrence during follow-up period of 42 months. In consideration that LEC in larynx have not been reported in South Korea yet, we introduce the clinical features and treatment outcomes of laryngeal LEC with literature review.

Schwannoma is a slow growing benign tumor that can occur anywhere in our body. About 25~45% cases of schwannomas occur in the head and neck, but intra-thyroidal schwannomas are very rare, and mostly are diagnosed by post-thyroidectomy pathologic study. In this article, we present a case of intra-thyroidal schwannoma diagnosed preoperatively with core needle biopsy. The patient underwent enucleation of the thyroid tumor, and the pathology of the tumor was confirmed as schwannoma. Few cases of intra-thyroidal schwannomas have been reported in the literature, but none of them have been diagnosed through core needle biopsy preoperatively. Preoperative diagnosis of intra-thyroidal schwannoma can be helpful when determining appropriate surgical extent and avoid unnecessary thyroidectomy.
