Abstract:
Amyloidosis is defined by tissue deposits of amyloid, which cause both functional and structural damage to organs. Three histopathological types of pulmonary amyloidosis have been described: tracheobronchial, nodular parenchymal, and diffuse parenchymal or alveolar septal types. Diffuse alveolar septal involvement of the lung is a rare form of primary pulmonary amyloidosis, with radiological features similar to those of pulmonary edema, pulmonary fibrosis, and lymphangitic carcinomatosis. Therefore, it is always challenging to diagnose alveolar septal involvement of pulmonary amyloidosis. Here, we report a case of alveolar septal involvement of pulmonary amyloidosis mimicking lymphangitic carcinomatosis, which was diagnosed from a transbronchial lung biopsy.
