Is reactive lymphoid hyperplasia cancer?

Reactive lymphoid hyperplasia (RLH) is a rare, benign, lymphocytic tumour-like lesion reported in various organs. It has been previously identified in 18 cases in the English-language literature, but only 5 of them were related to oncological disease.

Can a reactive lymph node become cancerous?

If the problem persists for longer than a couple of weeks, it might warrant a visit to the doctor. Other reasons to visit the doctor include: a lymph node that feels hard or rubbery to the touch.

What does a reactive lymph node look like on ultrasound?

Reactive LN: A lymph node was considered reactive if the node is oval in shape, hypoechoic with presence of central echogenic hilum, had unsharp borders, had no nodal calcification or ancillary features like necrosis or matting. On CDUS, a lymph node was considered reactive if central vascularity was maintained.

What kind of biopsies show reactive lymphoid hyperplasia?

Introduction Reactive lymphoid hyperplasia is a common pathologic finding from fine needle aspirates and core biopsies of peripheral lymph nodes. It is also a common finding from parenchymal lung and mediastinal lymph node biopsies.

How is age related to reactive lymphoid hyperplasia?

Reactive Lymphoid Hyperplasia. The age of patients is one of the most important factors in determining the nature of enlarged lymph nodes. In children, most lymphadenopathies are benign, whereas in adults, the probability of malignancy (metastatic carcinoma more so than lymphoma) increases with age ( 4 ).
