Analysis of the histopathological findings of lymph node biopsies at a tertiary care centre

Background Lymph nodes are spread throughout the body and are routinely checked for abnormalities. These lymph nodes have the potential to become infected or malignant. The swelling of lymph nodes and the nodes which are abnormal in terms of size and/or number is commonly known as lymphadenopathy. One of the most common causes of lymphadenopathy observed is reactive lymphadenitis followed by granulomatous lymphadenitis. For diagnosis of lymph node biopsies, excisional biopsy and histopathological analysis are considered as the ‘gold standard’.

Methods This is a retrospective, descriptive and a cross-sectional study of all the patients with lymph node biopsies seen in Bhaktivedanta Hospital and Research Institute from January 2018 till March 2022. Histopathology reports of lymph node biopsies of patients required at Bhaktivedanta Hospital and Research Institute were included in the study.

Results The most common diagnosis is of tuberculous lymphadenitis which accounted for 251 (53.2%) of the total 469 cases. Tuberculous lymphadenitis was most commonly observed in females (68.92%) as compared to males (31.07%). Cancer cases which accounted for 83 (17.70%) cases formed the second most common diagnosis in which females (53.01%) accounted for most cases as compared to males (46.99%).

Conclusions Enlarged lymph nodes should undergo fine needle aspiration cytology (FNAC), truecut biopsy and/or excisional biopsy for correct diagnosis. The diagnostic spectrum ranges from benign reactive to TB and also malignancies.
