Submandibular tuberculous lymphadenitis after endodontic treatment of the mandibular first premolar tooth: report of a case.

Cervical tuberculous lymphadenitis (scrofula) is an infectious granulomatous disease that requires a precise diagnosis. The differential diagnosis involves mainly the pathologic conditions involving the regional lymph nodes and the submandibulary salivary glands. Although tuberculous lesions generally develop secondary to pulmonary disease, clinical manifestations are occasionally seen with no evidence of involvement of the lungs. In this report, a case of tuberculous submandibular lymphadenitis developing after endodontic treatment of the mandibular first premolar tooth is described.
