[A case of B-cell lymphoma imitating bronchocentric granulomatosis].

A case is presented of primary, pulmonary B-cell lymphoma imitating bronchocentric granulomatosis. The initial manifestations were of multiple, pulmonary nodules, without intra- and extrathoracic lymph node, bone marrow and spleen involvement. Despite the initial removal of the affected pulmonary tissue the progression of the disease led to additional immunohistochemical evaluation of the resected tissue and final diagnosis. The authors also carry out a differential diagnosis of the reported changes.
