S15C6P7 Lymphomatoid Granulomatosis
BuiltWithNOF

S15C6P7-1: This is a continuation of the presentation of pathology from the same case as seen in pictorials S15C6P5. In this series of pictorials, the biopsy is representative of the changes seen in a lesion of the lung. Alveoli are collapsed and alveolar walls are irregularly thickened. Focally, there are loose infiltrates of lymphoid cells in the alveolar walls. Mucinous “organization bodies” (of Masson) project into, and fill, some of the alveoli.

S15C6P7-2: Loosely cellular, organization bodies project from alveolar walls into the lumens of alveoli. In this field, they are confluent, occupying the lumens of several alveoli. Organization bodies, of this type, generally are a sequela of a fibrinous alveolitis.

S15C6P7-3: Focally, alveolar spaces are collapsed. Alveolar walls are thickened and contain infiltrates of histiocytes and lymphoid cells.

S15C6P7-4: Atypical lymphoid cells are loosely sprinkled among histiocytes. There are scattered eosinophils. The infiltrate is angiocentric.

S15C6P7-5: The infiltrates are rich in histiocytes. Lymphoid cells have enlarged nuclei with irregular nuclei outlines.

S15C6P7-6: Focally, the mucinous matrix of the thickened alveolar walls shows fibrinoid degeneration. “Granulomatosis,” as characterized by Leibow, gave recognition to zones of necrosis, rather than providing a label for prominent patterns of granulomatous inflammation.
