Context and objective. Non-malignant lymphadenitis are the most prevalent hemopathies in sub-Saharan Africa. We determined the frequency and histological pattern of non-malignant lymphadenitis. Methods. A retrospective study was undertaken within 5 main pathology laboratories in Kinshasa during a 5-year period spanning from 2011 to 2015.

Among 413 (64%) non-malignant lymph node specimens analyzed, 52% were from female patients with a male-to-female sex ratio of 0.96.
