Fine needle aspiration (FNA) in HIV+ patients: results from a series of 655 aspirates.
There are many selected small series or case reports of FNAs in patients with HIV infection, but large series are rare and epidemic's characteristics have evolved over time. The current study, from a large public hospital in the USA, included women as well as men, hetero- and homosexuals, in-patients and out-patients, and deep radiologically guided aspirates as well as superficial masses. Of 655 FNAs, reactive or benign changes were present in 37% confirmed or suspected malignancy in 13%, specific infection with stainable organisms in 14%, and inflammation in 16%. Twenty percent of cases were inadequate for diagnosis. Most of the identifiable infections were associated with Mycobacterium tuberculosis, with fewer atypical mycobacteria, fungi and other bacteria. Clinically significant diagnoses were correlated with deep aspirate location and lesion size > 2 cm, confirming other studies which also identified tenderness and recent enlargement as important indicators. The liberal use of FNA in our HIV+ population has greatly reduced the necessity for surgical nodal resection, reassured clinicians in continuing observation of reactive lymphadenopathy, and allowed immediate therapy for specific infection, cyst or malignancy.
