Objective:
The aim of the study was to evaluate the contribution of microbiology, cytology, and anatomopathology in 50 cases of peripheral tuberculous lymphadenitis.
Methodology:
Our patients underwent bacteriological tests and cytology and/or histopathology for lymphadenitis.
Results:
Ziehl-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.
Conclusion:
Our 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.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis III
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
