BACKGROUND: To establish the usefulness of the FNA biopsy in the
clinical approach of peripheral adenopathies in AIDS patients, to
determinate its role in further therapeutic interventions and to compare
the frequency of different etiologies. METHODS: Patients selected for
FNA fulfilled tile following criteries: all were adults with confirmed
HIV infection and one or more persistent enlarged lymph nodes larger
than 3 cm. for more than 30 days. Cytologic exam, Gram-stained, Grocott,
Giemsa and Ziehl-Nielsen smears as well as bacterial, fungus and
mycobacterial culture were performed from the aspirated material.
RESULTS: Twenty-four FNA were analyzed. Forty-six percent (11/24) were
localized lymph nodes, mainly in cervical region. The FNA was positive
in 91.06% (22/24). There were 17 (77.3%) tuberculosis; 2 (9.1%)
histoplasmosis; 1 (4.5%) cryptococcosis; 1 (4.5%) metastatic anaplasic
cancer, and 2 (9.1%) non-Hodkin's lymphomas. One patient had two
microorganisms in the same node (M. tuberculosis and H. capsulatum).
CONCLUSION: FNA had a high diagnosis accuracy, with no false positive.
The main agent isolated was M. tuberculosis, since peripheral
tuberculous lymphadenopathy is the commonest form of extrapulmonary
tuberculosis in HIV patients in our country. The possibility of two
concurrent opportunistic agents in one single lymph node is highlighted.
The low ratio of cancer in our series compared to infectious etiology is
