Tuberculosis of the nasal fossa manifested by a polypoid mass.

Since the introduction of effective antituberculous chemotherapy, upper respiratory tract tuberculosis is infrequent; nasal involvement is a very rare form of this disease. In this localization, tuberculosis is usually unilateral and typically discloses a definite granular mass or an ulcer. We report a case manifested by an intranasal mass on computerized tomography scans that evolved as chronic rhinitis.
