Fig. 1B.Adult T-cell leukemia or lymphoma (acute type) in 75-year-old
woman. Photomicrograph of autopsy specimen obtained from left upper lobe shows
atypical lymphocytes infiltrating interstitium (arrows), with small
nodule formation (arrowheads). (H and E, x100)
Fig. 2.Adult T-cell leukemia or lymphoma (acute type) in 49-year-old
woman. High-resolution CT scan obtained 2 cm below carina shows fine reticular
pattern superimposed on background of ground-glass attenuation, crazy-paving
pattern. Right pleural effusion is also present.
Fig. 3B.Adult T-cell leukemia or lymphoma (lymphoma type) in
30-year-old man. Photomicrograph of surgical biopsy specimen obtained from
right upper lobe shows lymphocytes with mild nuclear atypia infiltrating along
bronchovascular bundles with mild fibrosis. (H and E, x100)
Fig. 4A.Adult T-cell leukemia or lymphoma (smoldering type) in
23-year-old woman. High-resolution CT scan obtained at level of dome of right
hemidiaphragm shows centrilobular nodules (tree-in-bud pattern) and mild
thickening of bronchial walls. Note mild bronchiectasis.
Fig. 4B.Adult T-cell leukemia or lymphoma (smoldering type) in
23-year-old woman. Photomicrograph of surgical biopsy specimen obtained from
right lower lobe shows atypical and mildly atypical lymphocytes infiltrating
wall of respiratory bronchioles extending into adjacent peribronchiolar
interstitium. (H and E, x40)
Fig. 5.Adult T-cell leukemia or lymphoma (acute type) in 34-year-old
man. High-resolution CT scan obtained at level of bifurcation of middle lobe
bronchus shows thickening of bronchovascular bundles (arrow). Note
small nodules (arrowheads).
Fig. 6B.Adult T-cell leukemia or lymphoma (smoldering type) in
35-year-old man. Photomicrograph of surgical biopsy specimen obtained from
left lower lobe shows numerous atypical lymphocytes infiltrating into
interstitium. Note mild congestive change. (H and E, x40)
Fig. 6C.Adult T-cell leukemia or lymphoma (smoldering type) in
35-year-old man. After treatment, follow-up CT scan shows improvement of
consolidation.
Fig. 6D.Adult T-cell leukemia or lymphoma (smoldering type) in
35-year-old man. Follow-up CT scan obtained 11 months after C shows
recurrence of consolidation in right upper lobe, where consolidation had not
been visualized on initial scan.
Fig. 7A.Adult T-cell leukemia or lymphoma (acute type) in 73-year-old
man. High-resolution CT scan obtained at level of division of middle lobe
bronchus shows nodules with air bronchogram in middle lobe.
Fig. 7B.Adult T-cell leukemia or lymphoma (acute type) in 73-year-old
man. High-resolution CT scan obtained at level of division of lingular
bronchus in left lung shows two nodules with air bronchogram.
Fig. 8A.Adult T-cell leukemia or lymphoma (acute type) in 38-year-old
woman. CT scan obtained at level of tracheal carina shows plaquelike
thickening of pleura (arrows). Right pleural effusion and lymph node
enlargement (arrowheads) can also be identified.
Fig. 8B.Adult T-cell leukemia or lymphoma (acute type) in 38-year-old
woman. Photomicrograph of surgical biopsy specimen obtained from right lower
lobe shows numerous atypical lymphocytes infiltrating both pleura and
interlobular septa (arrow). Note foamy cells existing in some
alveoli. (H and E x40)
