Illustrative examples of postmortem findings in the lungs: (A–E) Case 1: Clinical Diagnosis: pulmonary bleeding, most probably due to a central lung cancer. (A) Large transversal section shows a large bronchial carcinoma, centrally located with infiltration and with arrosion of large vessels and bronchi (A,B). Additionally, in the lower lobe, a second tumor was identified (A,C). Histologically, the central tumor was a poorly differentiated squamous cell carcinoma (D). The tumor in the lower lobe (E) was a well differentiated squamous cell carcinoma, due to the different morphology considered to be a second, independent malignancy. (F–H) Case 2: Clinical Diagnosis: diffuse metastasizing melanoma. F: multiple, partially inhomogeneous (*), partially well circumscribed (#) nodules and indurations in the lungs. Histological coexistence of acute bronchopneumonia (G, corresponding to *) and multiple intravascular infiltrations of melanoma (H, corresponding to #). No parenchymatous metastases were detected. (I–L) Case 3: Clinical Diagnosis: unclear pulmonary fibrosis. (I): Patchy consolidations in all lobes. (K) Corresponding CT scan. Histology showed organizing pneumonia (L). All histological stains are Hematoxylin/ and Eosin; original magnification 20×.
