Management of COVID-19 in lung transplant recipients is challenging. We report a case of a 71-year-old male who underwent bilateral lung transplantation with an unexpected case of COVID-19. The patient had been fully vaccinated. The patient and donor tested negative for pretransplant COVID-19. On routine bronchoscopy on day 1 after transplant, the COVID-19 test was positive. Mycophenolic mofetil and the second dose of basiliximab were skipped, but tacrolimus and prednisone were continued. He was treated with casirivimab/imdevimab and remdesivir. He was discharged on day 14 and has had no episodes of acute rejection during the 3 months.

Acute interstitial pneumonia (AIP), also known as Hamman-Rich syndrome, is a rare and rapidly progressive idiopathic interstitial lung disease with a high mortality rate. Treatment is limited to supportive care and empirical high-dose steroids; however, outcomes are generally poor. There are few reports of lung transplantation (LTx) in patients with AIP.We retrospectively identified patients with AIP among those who underwent LTx at our center between January 2008 and December 2020.During the study period, 4 patients with AIP underwent bilateral LTx: 3 men and 1 woman, between 30 and 57 years of age. The lung allocation score ranged between 71 and 89. Of the 4 patients, 2 needed extracorporeal membrane oxygenation and mechanical ventilation (MV) and 1 needed MV preoperatively. Time of onset to transplant ranged from 1 to 3 months. None of the patients had primary graft dysfunction after LTx; 2 had acute cellular rejection and 1 had chronic lung allograft dysfunction. The 4 patients are alive with survival ranging between 1 and 12 years after LTx.AIP should be considered in patients with acute respiratory failure without a clear etiology. Our study showed that LTx led to good outcomes and should be considered as a treatment option in appropriate candidates.

A 68-year-old man with interstitial pulmonary fibrosis underwent bilateral lung transplantation. Histopathologic examination of hilar lymph nodes in the explanted lungs showed effacement of normal nodal architecture by the proliferation of small lymphocytes, consistent with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL). Unexpectedly discovered malignancies at the time of lung transplantation is uncommon, especially in the lymph nodes. The clinical management was challenging because of attempts to balance treatment of CLL and immunosuppressive treatment to prevent graft rejection. Here, we report a case of incidentally detected CLL in hilar lymph nodes with explanted lungs and review the relevant literature.
