Presented is a 36-year-old with a huge chronic Submental lymphadenopathy in a seronegative patient of 7 years duration. Histology revealed non-caseating tuberculosis. Tuberculosis should be considered in Submental lymphadenopathy. Despite the long duration, the absence of cold abscess, and or sinus formation may be an indication of the non-caseating tuberculous lymphadenopathy.展开更多
