Fine needle aspiration biopsy of tuberculous cervical lymphadenopathy.
Fine needle aspiration biopsies of 42 histologically confirmed tuberculous cervical lesions were studied. Thirty-four patients had subsequent excision of cervical lymph nodes and eight had incision and drainage of cervical abscesses. All aspirates except two (which were inadequate) were satisfactory for diagnosis and contained inflammatory cells. Twenty-seven smears revealed cells typical of granulomatous lymphadenopathy, that is, epithelioid and multinucleated giant cells. Of all aspirates, 17 smears had bacteriological staining by Ziehl-Nielsen technique, nine of which (53%) were positive for acid-fast bacilli. An aspiration biopsy diagnosis of granulomatous or tuberculous cervical lymphadenopathy was made in 30 patients (71%). In regions where mycobacterial infection is common, the presence of granulomatous changes in lymph node aspirates is highly suggestive of tuberculosis. When the aspirates contain purulent material or when tuberculosis is suspected, staining and culture for mycobacteria should be performed. FNA biopsy is a sensitive, specific and cost-effective way to diagnose tuberculous cervical lymphadenopathy and is recommended.
