Most Typical presentation of the Oral Lesions of Tuberculosis

What is the most typical presentation of the oral lesions of tuberculosis?

a. Mucosal lesions with a cobblestone appearance 
b. Nonhealing ulcer
c. Mucositis 
d. Erythematous bullseye

The correct answer is B: The oral lesions of tuberculosis are thought to result from the presence of organisms brought into contact with the oral mucosa by sputum. A nonhealing ulcer, which is impossible to differentiate clinically from carcinoma, is the most common presentation in the mouth. Ulcers are most consistently present on the lateral borders of the tongue and may have a purulent center. Lymphadenopathy also may be present. Diagnosis is made by histologic examination and demonstration of organisms in the tissue.
