We present three cases with an atypical clinical course of organizing pneumonia (OP) secondary to COVID-19. Three patients were discharged with satisfactory improvement after standard steroid therapy for COVID-19. Shortly after the completion of treatment, the patients experienced a flare-up of symptoms. Imaging results showed new lesions in the lungs. Transbronchial lung cryobiopsy showed histological findings consistent with OP in all cases. Steroids were administered, and a good therapeutic response was observed. This report is the first to describe pathologically confirmed OP that developed after recovery from COVID-19. Careful follow-up is advisable for patients who have recovered from COVID-19.

Pulmonary artery agenesis (PAA) is a rare congenital vascular anomaly usually diagnosed during infancy. We herein report a 67-year-old man with PAA manifesting as massive hemoptysis. Contrast-enhanced computed tomography of the chest revealed the diagnosis of PAA, which we speculated to have resulted in the present event. Detailed angiography provided more accurate information on the pulmonary vasculature and collateral circulation, which helped us plan tailored treatment. Although very rare, we must consider the possibility of PAA in adults with unexplained hemoptysis.

In 1982, we reported a case of retroperitoneal fibrosis (RPF) exhibiting various clinical manifestations. Our current understanding of immunoglobulin G4 (IgG4)-related disease led us to consider it as a possible diagnosis because all of the patient's clinical features could be explained by this disease entity. To confirm our hypothesis, we re investigated the histopathological findings of resected specimens that had been stored for 35 years postoperatively. Typical pathological findings together with predominant IgG4+ plasma cell infiltration confirmed a potential diagnosis of IgG4-related RPF. Furthermore, we observed positive immunohistochemical staining for several molecules associated with T regulatory and T follicular helper cells.
