Introduction:

Histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum, whose clinical manifestations range from asymptomatic to disseminated and highly fatal disease.

Objective:

To present the case of a patient diagnosed with disseminated histoplasmosis and SARS-CoV-2 infection.

Clinical case:

The case of a 79-year-old man is presented with a history of systemic arterial hypertension and type 2 diabetes mellitus. He was admitted for a week with nonproductive cough, dyspnea, and fatigue on moderate exertion, and reported having a positive antigen test for SARS- CoV-2. During hospitalization, he presented clinical deterioration, needing mechanical ventilation due to respiratory infection associated with COVID-19. Despite this, he presented lymphadenopathy, hepatosplenomegaly, and umbilicated skin-colored papules suggestive of disseminated fungal infection. Suspecting co-infection, infection by Histoplasma capsulatum was confirmed by means of mini-bronchoalveolar lavage and antifungal treatment was initiated; however, the patient presented persistent clinical deterioration and died.

Conclusion:

Cases of co-infections with COVID-19 in patients without chronic diseases or immunosuppressive states are rare, their diagnosis being a challenge for medical personnel and requiring consideration of pulmonary fungal infections such as cryptococcosis or histoplasmosis in associated respiratory failure. to SARS-CoV-2 infection.
