Abstract
-
Malignant laryngeal tumors include a variety of histologic types with different biologic features, each calling for a different therapeutic approach and giving rise to a different prognosis. We experienced a case of laryngeal adenosquamous carcinoma which is an extremely rare neoplasm in larynx. The lesion is histologically distinctive because of the presence of mixed areas of unequivocal adenocarcinoma and squamous cell carcinoma. Differential diagnosis include adenoid squamous cell carcinoma and mucoepidermoid carcinoma. It is found that combined surgery and additional radiation therapy is necessary because the biologic behavior and prognosis of this neoplasm are considered as more aggressive and worse than that of conventional squameus cell carcinoma.
