INTRAVASCULAR LYMPHOMATOSIS DIAGNOSED BY TRANSBRONCHIAL LUNG-BIOPSY

Intravascular lymphomatosis is a rare lymphoma presenting a variety of symptoms due to proliferation of tumour cells within blood vessels in the brain, the skin and other organs. This disease is generally consi dered to be highly malignant, but to be relatively susceptible to comb ined chemotherapy, when diagnosed in the early stage. We describe a ca se of intravascular lymphomatosis, presenting with diffuse interstitia l shadows on chest radiographic image, which could be diagnosed by tra nsbronchial lung biopsy. The patient showed a good response to combine d chemotherapy. We propose that transbronchial lung biopsy is a useful procedure for the diagnosis of intravascular lymphomatosis.
