  • Title: [A case of diffuse endobronchial infiltration in a patient with non-Hodgkin's lymphoma].

    Abstract:
    A 38-year-old man with diffuse endobronchial infiltration with non-Hodgkin's lymphoma (NHL) is reported. He was admitted to our hospital on November 1990 because of lymph node swelling. Physical examination on admission revealed left axillary, bilateral cervical and inguinal lymph node swelling. Chest and abdominal CT scan showed para-aorta lymph node swelling, mild splenomegaly and heterogeneous density of the liver, although hilar and mediastinal lymphadenopathy were not found. Microscopic examination of the biopsy specimen obtained from the right inguinal lymph node and liver revealed NHL (B cell lymphoma, diffuse, mixed type). After two courses of chemotherapy, a chest roentgenogram showed bilateral hilar lymphadenopathy and reticular shadows. CT scan demonstrated a thickening of the left main bronchus. Bronchoscopic examination revealed a small submucosal nodule in the left main bronchus on February 1991, from which the biopsy specimen revealed NHL infiltration similar to that of the lymph node. At follow-up bronchoscopic examination, in spite of chemotherapy, scattered NHL infiltration was found in the submucosal space of the left vocal cord, carina and the bifurcation between left upper and lower bronchi. In patients with NHL, endobronchial involvement is rare. In this case, diffuse endobronchial infiltration was not thought to be direct invasion from the lymph node but hematogenous or lymphatic spread to the bronchi.
