Evaluation of peripheral lymphadenopathy with excisional biopsy: six-year experience

Abstract

Background: Lymphadenopathy (LAP) may be the first symptom of many diseases. We aimed to investigate peripheral LAP results taken by excisional biopsy.

Methods: Histopathological examination of 185 lymph node biopsy specimens were evaluated between January 2009 and April 2015 in Istanbul Private Ekin Pathology Laboratory, retrospectively.

Results: The average age of patients ranged from 1 to 86 was 41.01 ± 20.62 years. 87 of were female, 98 of male. 62 (33.5%) of excisional biopsy materials were benign lesions and 123 (66.5%) of malignant. Benign lesions were consisted of reactive hyperplasia, cat-scratch disease, toxoplasmosis, necrotizing/non-necrotizing granulomatous. Of these patients, 40 had nodes with reactive hyperplasia (15 female/25 male, mean age: 27.35 y), 14 had necrotizing granulomatous disease (9 female/5 male, mean age: 39.86 y), 2 non-necrotizing granulomatous disease (1 female/1 male mean age: 43 y), 4 had cat-scratch disease (1 female/3 male mean age: 54.25 y), 1 toxoplasmosis (26 y, female), 1 Kikuchi disease (25 y, female). In the evaluation of malign lesions; 38 were Hodgkin lymphoma (HL) (20.5%, 17 female/21 male, mean age: 34.89 y) 77 had non-Hodgkin lymphoma (NHL) (41.6%, 37 female/40 male, mean age: 52.26 y), 8 metastasis (4.3%, 5 female/3 male, mean age: 53.5 y). Reactive LAP observed most common in cervical region, NHL in axillary-abdomen-inguinal-mediastinum and HL in the supraclavicular region.

Conclusion: Excisional biopsy can be applied safely with minimal morbidity and mortality and a gold standard diagnostic method for LAP. Although LAP is mostly related with benign lesions, malignancy should be kept in mind in differential diagnosis.
