Pulmonary MALT lymphoma associated with interstitial pulmonary disease.

Interstitial lung disease (ILD) and low-grade Mucosa-associated B-cell lymphoma (MALT lymphoma) are two different disorders of the respiratory system. In some cases, pulmonary MALT lymphoma is seen presenting with interstitial lung disease. We report a case of 42-year-old man presenting with a pulmonary MALT lymphoma associated with interstitial lung disease.
