Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Amyloidosis is a rare, multisystem disease that leads to deposition of misfolded proteins in various organs. This case report presents a patient with cancer with a rare diagnosis of diffuse alveolar-septal transthyretin (TTR) amyloidosis with subsequent protein electrophoresis identifying monoclonal gammopathy of unknown significance. It highlights the association of amyloidosis with malignancy and the importance of including workup for plasma cell dyscrasias in patients found to have TTR amyloidosis.

Pulmonary amyloidosis is an extremely rare disease, often detected incidentally because of its asymptomatic nature and potential to result in fatal outcomes. In this study, we aimed to present the clinical and radiological features of patients diagnosed with pulmonary amyloidosis by biopsy. This descriptive study included 21 patients with pathologically diagnosed pulmonary amyloidosis.

Background: This study presents a case of rapidly developing respiratory failure due to antisynthetase syndrome (AS) following coronavirus disease 2019 (COVID-19) in a 33-year-old man diagnosed with Klinefelter syndrome (KS).
Case Summary: A 33-year-old man with a diagnosis of KS was admitted to the Department of Pulmonary and Critical Care Medicine of a tertiary hospital in China for fever and shortness of breath 2 wk after the onset of COVID-19. Computed tomography of both lungs revealed diffuse multiple patchy heightened shadows in both lungs, accompanied by signs of partial bronchial inflation.

Large amounts of net electrical charge are known to accumulate on inhaled aerosols during their generation using commonly-available inhalers. This effect often leads to superfluous deposition in the extra-thoracic airways at the cost of more efficient inhalation therapy. Since the electrostatic force is inversely proportional to the square of the distance between an aerosol and the airway wall, its role has long been recognized as potentially significant in the deep lungs.
