Abstract:
Background. Tuberculosis lymphadenitis is one of the most common forms of all extrapulmonary tuberculosis. Objective. To
evaluate the magnitude of M. tuberculosis from lymph node biopsy paraffin-embedded sections among suspected patients visiting
the Jimma University Specialized Hospital. Method. A cross-sectional study design of histological examination among lymph node
biopsy paraffin-embedded sections by Ziehl-Neelsen and hematoxylin/eosin staining technique was conducted from December,
2009, to October, 2010, at the Department of Medical Laboratory Science and Pathology. Result. Histopathological examination
of the specimens by hematoxylin and eosin staining technique revealed the presence of granulomas. But for the caseation and
necrosis they were present in 85% cases of nodal tissue biopsies. From those, 56.7% were from females. The presence of acid-fast
bacilli was microscopically confirmed by ZN staining in 37 (61.7%) of the nodal tissue biopsies. Conclusion and Recommendation.
Tuberculosis lymphadenitis is significantly more common in females. Hence, attention should be given for control and prevention
of extrapulmonary
