2. B cell lymphoma
The patient’s disease process falls into the category of lymphoproliferative pulmonary disorders (LPDs). These disorders can be classified into reactive or non-neoplastic and malignant disorders (Table 1).
The reactive LPDs are associated with immunological disturbances and are commonly seen in patients with immunodeficiency or autoimmune disorders. Often these are associated with Epstein Barr virus infection especially in lymphomatoid granulomatosis or AIDS-associated lymphoma.
It is unclear what role azathioprine might have played in this patient’s disease process. Azathioprine has been associated with an increased risk of lymphoma but these usually have been associated with Epstein Barr virus infection and treatment for Crohn’s disease.
