Extrafollicular reticulum cells in lymph nodes are heterogeneous. They express cytokeratins, desmin, and/or vimentin as their intermediate filament profile. Using those markers, we undertook an immunohistochemical study of human lymph nodes under various pathologic conditions. Samples included 15 simple reactive lymph nodes, 7 follicular hyperplasia, 1 necrotizing lymphadenitis, 4 tuberculous l...

AIM To evaluate complicated cases of tuberculous cervical lymphadenitis by ultrasonography and computed tomography in order to detect more lymph nodes, and to study their lesions. MATERIAL AND METHODS Total 27 patients of tuberculous cervical lymphadenitis previously proved bacteriologically or histopathologically on anti-tuberculosis treatment (ATT) presenting with complications were taken f...

Tuberculous lymphadenitis without pulmonary manifestation is an uncommon entity in developed countries, and the possibility of tuberculous infection is usually ignored in the differential diagnosis of lymphadenopathy. Therefore, appropriate treatment may be delayed. Paralysis of the recurrent laryngeal nerve caused by mediastinal lymphadenopathy due to tuberculosis is an extremely rare conditio...

Chylothorax is a rare clinical condition characterized by high triglyceride and low cholesterol levels in milky pleural aspirate. Generally, it occurs through leakage of chyle as result of trauma or malignancy. Chylothorax due to tuberculous lymphadenitis is very rare clinical condition that has only been documented in a few cases. Although precise pathogenesis is not known, enlarged mediastina...

Tuberculosis (TB) is a prevalent systemic bacterial infectious disease usually caused by Mycobacterium tuberculosis. It is estimated that approximately 8 million people develop TB each year, and 3 million people die of complications associated with the disease. In this article we report a case of a 17-year-old female patient with a painful swelling in her right submandibular region. She was dia...

This report presents a case of tuberculous lymphadenitis that was difficult to diagnose using polymerase chain reaction analysis. An 80-year-old Japanese female was hospitalized due to swollen cervical lymph nodes. Her lymph node tests revealed paradoxical polymerase chain reaction results. Polymerase chain reaction analysis of two biopsy tissues using the Cobas TaqMan revealed a positive resul...

This report describes a case of portal hypertension caused by periportal tuberculous lymphadenitis. There were a few reports of portal hypertension associated with tuberculosis. A 27-year-old man was admitted to the hospital because of recurrent hematemesis for 7 days. There was a history of mediastinal tuberculous lymphadenitis 3 years earlier that was treated with isoniazide, rifampin, ethamb...
