Background:
The increasing prevalence of extrapulmonary manifestation of tuberculosis with the HIV scourge is a cause for concern.
Objective:
To determine the role of fine needle aspiration cytology (FNAC) in the diagnosis of extrapulmonary tuberculosis.
Patients And Methods:
This is a consecutive 9-year analysis of patients with peripheral lymphadenopathy. All the patients had fine needle aspiration. Smears were made, fixed in 95% alcohol and stained with hematoxylin and eosin and Zeihl Neelsen stains.
Results:
48 patients, 31 males and 17 females, were analyzed. The mean age was 27.9 years. Aspirates were mainly from cervical lymph nodes. Four patients were HIV 1 seropositive. Macroscopically, 23 (48%) of the aspirates were purulent and 7 (14.6%) had caseous material. Microscopy showed granular eosinophilic material (caseation), multinucleated giant cells, epithelioid cells, neutrophils and lymphocytes. Staining for acid-fast bacilli was positive in 23 (48%) cases.
Conclusion:
Early diagnosis of extrapulmonary tuberculosis in a resource-limited setting can be achieved with fine needle aspiration cytology technique (FNAC). This will ensure prompt treatment and thus reduce attendant morbidity and mortality.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
