ABSTRACT ObjectiveThe aim of the study was to evaluate the contribution of microbiology, cytology, and anatomopathology in 50 cases of peripheral tuberculous lymphadenitis.MethodologyOur patients underwent bacteriological tests and cytology and/or histopathology for lymphadenitis.ResultsZiehl-Neelsen stains and cultures were positive in only 29.7% and 10.8% of cases respectively. The diagnosis was confirmed by cytology in 31.3% of cases (10/32) and by histology in 58.6% of cases (27/46). Granulomas were observed in 46.8% (15/32) of needle aspirates and 76% (35/46) of surgical biopsies.ConclusionOur study reveals a weak contribution of conventional microbiological techniques. Cytology remains the procedure of choice in endemic countries. Excisional biopsy may be performed in case of doubt.

    ABSTRACT: Each year, there are more than eight million new cases of tuberculosis and 1.3 million deaths. There is a renewed interest in extrapulmonary forms of tuberculosis as its relative frequency increases. Among extrapulmonary organs, pleura and lymph nodes are the most common. Their diagnosis is often difficult and is based on clinical, radiological, bacteriological and histological findings. Extrapulmonary lesions are paucibacillary and samplings, in most cases, difficult to obtain, so diagnosis is often simply presumptive. Nucleic acid amplification tests, which are fast and specific, have greatly facilitated the diagnosis of some forms of extrapulmonary tuberculosis. However, their sensitivity is poor and a negative test does not eliminate the diagnosis. Treatment is the same as for pulmonary forms, but its duration is nine to 12 months for central nervous system and for bone tuberculosis. Corticosteroids are indicated in meningeal and pericardial localizations. Complementary surgery is used for certain complicated forms.
