Abstract

Nodular lymphoid hyperplasia is a very rare benign disease and usually shows consolidation on chest X-ray with symptoms of pneumonia due to the proliferation of lymphoid cells in the lung parenchyma. It is common for patients to be diagnosed with pneumonia and treated with antibiotics, but patients often enter a cycle of repeated improvement, followed by aggravation of symptoms. At this point, surgical diagnostic tools are considered in order to differentiate between malignant disease and interstitial lung disease. Here, we report 2 cases of patients with nodular lymphoid hyperplasia and review the associated references.
