Imatinib inhibits bone marrow-derived c-kit+ cell mobilisation in hypoxic pulmonary hypertension.

with sarcoidosis usually preceding lymphoma. Because many features of sarcoidosis and lymphoma are similar, histological confirmation of malignancy is necessary, especially if new nodal disease and splenomegaly are present. Sarcoidosis, although rare, may complicate the course of lymphoma. Prominent features of sarcoidosis were respiratory symptoms, high ACE levels, BHL in asymptomatic subjects and lung disease. Despite the limitations of this study, the above described features should alert clinicians to pursue a second diagnosis, in order either to properly diagnose malignancy in the sarcoidosis setting or to save cancer patient from a potentially toxic treatment escalation due to a presumed lymphoma recurrence.
