Cytomorphology in Tuberculous Lymphadenitis and Correlation With Acid Fast Bacilli Detection by Papanicolaou, Auramine-Rhodamine Fluorescence and Ziehl-Neelsen Techniques.

ABSTRACT:

Background

Tuberculosis (TB) is a common cause of lymphadenopathy in developing countries. Fine needle aspiration cytology (FNAC) along with acid fast bacilli (AFB) detection is an invaluable diagnostic test. Fluorescent methods for AFB detection have greater sensitivity as compared to the Ziehl-Neelsen (ZN) method.

Methods

The incidence of TB lymphadenitis was determined among all lymph nodes aspirated over 5 years, from January 1993 to May 1998 in an Indian referral hospital. Cytomorphological spectrum was studied in 234 smears, and AFB positivity was determined by Papanicolaou (PAP), Auramine-Rhodamine (AR) fluorescence as compared to the ZN method.

Results

Of a total of 6592 lymph node aspirates, 33.86% were diagnosed as tuberculosis; maximum patients were between
