Diagnostic challenge of dyspnea in the context of the COVID-19 pandemic wave: a case report.

Background: Since its discovery, COVID-19 has often been the first diagnosis of dyspnea and asthenia, especially during the pandemic waves. However, it is not always COVID-19. We report a particular case of a late-diagnosed HIV-positive patient in Madagascar.

Case Presentation: A 21-year-old male patient was admitted to a hospital center in Antananarivo for dyspnea and poor general condition. Physical examination revealed hypoxemia of 85% on room air. His chest X-ray showed bilateral reticular-micronodular opacities. He was suspected and treated for COVID-19. On the 15th day of hospitalization, HIV-1 infection complicated by probable pneumocystis was diagnosed. On the other hand, a multimetastatic testicular cancer was also suspected. The patient died after a few hours of hospitalization in the intensive care unit.

Conclusion: This was a case of an HIV-positive patient belatedly diagnosed in the complications stage during the COVID-19 pandemic wave. The investigation of the differential diagnoses remains crucial to avoid serial misdiagnosis and to adjust therapeutic management.
