Abstract
|
|
|
|
Verrucous carcinoma was first described by Ackerman who reported a case of verrucous carcinoma of the oral cavity. While it is primarily occurred in oral cavity, larynx is the second most affected site, accounting for nearly 35% of cases. It is a rare variant of well-differentiated squamous cell carcinoma and comprises 1% to 4% of all laryngeal carcinomas. It is characterized by locally invasive, slow growth and the surface shows papillary fronds with prominent hyperkeratosis. Because of the benign appearance and difficulty of the tissue diagnosis, it is often undiagnosed or misdiagnosed. The primary treatment modality is surgery and the extent of surgical resection may be guided by T stage. We experienced a case of verrucous carcinoma of larynx in a patient with hoarseness lasted for about 2 years and had difficult to diagnosis and treatment. Therefore we report this case with a brief review of literature.
