Fine needle aspiration cytology (FNAC) in the diagnosis of granulomatous lymphadenitis.
OBJECTIVE
To determine the final histological and clinical diagnosis of patients with granulomatous lymphadenitis on fine needle aspiration cytology (FNAC).


METHODS
A retrospective cohort study was carried out over a five year period in a tertiary referral hospital. FNAC of 22 patients with granulomatous lymphadenitis was reviewed and correlated with the final histological diagnosis and clinical outcome.


RESULTS
Fourteen cases (64%) underwent surgical biopsy for histological assessment. A definitive diagnosis on FNAC with ancillary investigations was achieved in 82% (18 out of 22) of the cases: four Hodgkin's lymphoma, two non-Hodgkin's lymphoma (NHL), five tuberculosis (TB), two toxoplasmosis, one sarcoidosis and four benign reactive changes.


CONCLUSIONS
A significant number of cases of FNAC diagnosed granulomatous lymphadenitis have an identifiable underlying cause. Patients with reactive cytological changes, who clinically appear benign, can avoid unnecessary surgery.
