Abstract

Myxoma is an uncertain mesenchymal cell origin, characterized by irregular round, stellate or spindle cells sur-rounded by the matrix containing abundant mucoid material and scant vascularity. Their occurrence in descen-ding order of frequency is in the heart, subcutaneous tissue, bone and genitourinary tract. In the head and neck region, the most predilection sites are mandible and maxilla(more than 80%). Laryngeal myxoma is extremely rare：only 5 cases have been reported in the English literature. We report a rare case of laryngeal myxoma. A 60-year-old man with hoarseness visited the out-patient department. The mass was located between the vocal fold and the vocal ligament, filling with the left laryngeal ventricle. We planned the laryngo-microsurgery and suc-cessfully excised using CO 2 laser. The histopathologic finding revealed the myxoma. After 18 months of surgery, there is no evidence of recurrence and mucosal scarring in the vocal fold. This report is the first case of laryn-geal myxoma involving the laryngeal ventricle and the true vocal cord together.

Key Words: Myxoma, Laryngeal ventricle, True vocal cord
