Abstract
Nodular lymphoid hyperplasia (NLH) is a benign lymphoproliferative disease that can affect the lung. Because of its rarity, little is known about the etiology and natural history of NLH. Most cases are usually asymptomatic and found incidentally on imaging studies. Imaging finding of NLH has shown most commonly as a solitary lesion, although multifocal pulmonary nodules may be seen. Surgical resection has proved curative in the cases previously described. We report a rare case of NLH in a 55 year-old man who presented with bilateral multiple pulmonary nodules on chest radiography. Open biopsy was performed from the upper and lower lobe of the left lung. The lesions were pathologically diagnosed as pulmonary NLH. Multifocal residual nodules in both lungs remain stable without spontaneous regression during the 3 years of follow-up.
Key Words: Lung, Pseudolymphoma, Lymphoproliferative disorder
