[Coccidioidomycosis: a new brazilian case]

Area of Science:

• Mycology
• Infectious Diseases
• Pulmonology

Background:

• Coccidioidomycosis is a fungal infection endemic to arid and semi-arid regions.
• The causative agent, Coccidioides immitis, thrives in soil and is inhaled as dust.
• Northeastern Brazil's semi-arid climate presents a potential environment for C. immitis.

Observation:

• A farm worker in rural Bertolinia, PI, Brazil, presented with severe chest pain and fever.
• The patient reported inhaling dust while digging a water well during the dry season.
• Histopathological examination of lung tissue revealed immature and mature spherules of C. immitis.

Findings:

• This case represents the twelfth autochthonous (locally acquired) instance of coccidioidomycosis in Brazil.
• All identified cases have occurred in native inhabitants of Brazil's semi-arid Northeastern region.
• The findings support the hypothesis that soil disturbance in dry conditions facilitates Coccidioides spore inhalation.

Implications:

• This case underscores the importance of recognizing pulmonary coccidioidomycosis in endemic areas.
• Environmental factors in Northeastern Brazil may favor the presence and transmission of C. immitis.
• Public health awareness and diagnostic vigilance are crucial for managing this fungal infection in at-risk populations.
