Sinonasal Inverted Papilloma Associated with Adenoid Cystic Carcinoma

Inverted papilloma is the most common benign tumor of the paranasal sinuses with the possibility of malignant transformation. On the one hand, adenoid cystic carcinoma (ACC) is a rare malignant neoplasm that arises from the secretory glands. Sinonasal ACC accounts for 10%–25% of all head and neck AC...
