, Chest computed tomography scans showing (A) subcarinal adenomegaly and (B and C) ground-glass opacities with mosaic pattern and interlobular septal thickening. (D-F) Cytology and histology showing lymphoproliferation: (D) BAL cytospins: massive lymphocytosis (stained with MayGrünwaldGr¨Grünwald-Giemsa); (E) whole biopsy slide showing almost total villous atrophy with an inflammatory background, presence of a mononuclear material with very dense focal regions of increased intraepithelial lymphocytes (hematoxylin and eosin-stained section); and (F) accessory salivary gland biopsy: massive lymphoid infiltrate
