Peripheral tuberculous lymphadenitis or "scrofula" refers to lymphadenopathy of the neck, typically resulting from an infection in the lymph nodes caused by either tuberculous or non-tuberculous mycobacteria. It is the most common form of extrapulmonary tuberculosis, with the cervical lymph nodes being the most commonly affected sites. The usual signs and symptoms include the appearance of a chronic, painless mass in the neck that persists and usually grows over time. This mass is called a "cold abscess" because there is no accompanying local warmth or redness, and the overlying skin acquires a violaceous color. Epidemiological characteristics differ from those of pulmonary tuberculosis, and clinical manifestations may vary, making diagnosis challenging. Response to therapy may be slow or paradoxical, with frequent development of enlarging or new lymph nodes during and even after effective treatment. This case report presents a 27-year-old male patient with progressive swelling in the right submandibular region.
