    System
    Pathology Slides

    Asbestosis • Diffuse pulmonary
    interstitial fibrosis + asbestos
    bodies (golden brown, fusiform
    or beaded rods with a translucent
    center and consist of asbestos
    fibers coated with an iron-
    containing proteinaceous
    material)

    • Ferruginous bodies – other


    inorganic particulates coated with
    similar iron-protein complexes

    • Pleural plaques – most


    common manifestation; well-
    circumscribed plaques of dense
    collagen that are often calcified.
    Emphysema
    Bronchopneumonia
    Necrotizing PNA
    Necrotizing PNA + Lung Abscess.
    Cavity filled with bacteria and
    neutrophils; no alveoli.
    Organizing Pneumonitis
    Chronic Passive Congestion
    Hyaline Membrane Disease
    Large Cell CA
    Small Cell CA
    Squamous Cell CA
    Bronchioalveolar Carcinoma
    [BRONCHIOLOALVEOLAR CARCINOMA, MUCINOUS]. Bronchioloalveolar
    carcinoma (BAC) is a type of adenocarcinoma that grows along alveolar septae. Two
    main subtypes are recognized: mucinous and non-mucinous. This mucinous type
    BAC shows normal alveoli on the upper left corner and BAC on the right lower
    corner. Radiographically BAC may present as consolidation mimicking pneumonia
    and thus may evade correct identification.
