A 22-year-old male presented with multiple bilateral nodular shadows in the lungs by chest radiograph. He had been asymptomatic and showed no significant abnormal findings in laboratory examinations. He underwent a diagnostic partial lobectomy, and was diagnosed as having primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma; i.e. bronchus-associated lymphoid tissue (BALT) lymphoma/BALToma. Neither t(11;18)(q21;q21) chromosomal translocation nor API2-MALT1 chimeric transcript was found at diagnosis. Epstein-Barr virus (EBV) was also not detected in lymphoma cells. He had been a nonsmoker, and had also never shown any associated autoimmune disorders, chronic inflammatory lung diseases or human immunodeficiency virus (HIV) infection. However, he had suffered from moderate atopic dermatitis on his arms from childhood. It appears necessary to clarify whether atopy might play a role in the pathogenesis of API2-MALT1(-) BALT lymphoma for HIV(-) young patients who do not exhibit any other antecedent chronic antigenic stimulations.

Common variable immunodeficiency is one of the most frequent immunity alterations. The most common clinical presentation occurs with recurrent respiratory infections, from pneumonia to otitis, and may be associated with other diseases such as bronchiectasis or interstitial lung diseases. We report the case of a 28-year-old patient with frequent respiratory infections and nodular pulmonary infiltrates, who was diagnosed with common variable immunodeficiency and follicular bronchiolitis. In some cases, follicular bronchiolitis is associated with immunodeficiencies and should be included in a differential diagnosis with lymphoid nodular hyperplasia, lymphocytic interstitial pneumonia and low-grade BALT lymphoma.
