Thapa S, Ghosh A, Ghartimagar D, Narasimhan R, Prasad T, Talwar OP

Abstract:
Background Lymphadenopathies are the clinical manifestation of enlargement of lymph nodes which are a common occurrence and are processes of lymph nodes in response to a variety of exogenous and endogenous stimulants. The vast majority of enlarged lymph nodes are non-neoplastic. Objective The objective of the study is to analyze the spectrum of non-neoplastic lesions of superficial lymphadenopathies with their histomorphological features. Method This was a retrospective hospital based study done in the department of Pathology. All cases of superficial lymph node biopsies received during a period of 7 years were retrieved and divided into 2 broad categories: neoplastic and non-neoplastic. The latter group is the material for the present study. The diagnosis was made on morphological basis. Result Of all the 268 superficial lymph node biopsies, 25.4% (68 cases) were neoplastic and 74.6% (200 cases) were non-neoplastic. The non-neoplastic cases were further categorized into non-infectious 60.5% (121 cases) and infectious 39.5% (79 cases). Neck node (70%) was the most common site of involvement. There were 102 male and 98 female patients with male to female ratio 1.04:1. The age range of the patients was 2 years to 83 years with a mean of 27.16 years and most common being 11-20 years 29% (58 cases). Majority of the cases were non-specific reactive lymphadenitis 84.3% (102 cases) followed by tuberculosis 36.5% (73 cases). Conclusion The major cause for the superficial lymphadenopathy was found to be non-neoplastic etiology with slight male predominance. Reactive lymphadenitis was the leading cause unlike the studies done in other Asian and Tropical countries where tuberculosis was more common.
