Bony involvement in paracoccidioidomycosis

Area of Science:

• Mycology
• Pediatric Infectious Diseases
• Skeletal Radiology

Background:

• Paracoccidioidomycosis is a systemic fungal infection endemic to Latin America.
• Bony involvement is an uncommon manifestation, particularly in pediatric cases.
• Early recognition is crucial for timely treatment and improved outcomes.

Observation:

• A 4-year-old boy presented with symptoms suggestive of a bone disorder.
• Radiographic examination of the extremities demonstrated diffuse, permeative metaphyseal bone destruction.
• The radiographic pattern, while nonspecific, raised suspicion for infectious or neoplastic processes.

Findings:

• The observed bone destruction in the pediatric patient was consistent with a rare presentation of paracoccidioidomycosis.
• Histopathological or microbiological confirmation of Paracoccidioides brasiliensis is essential for definitive diagnosis.
• This case underscores the importance of considering endemic mycoses in the differential diagnosis of pediatric bone lesions.

Implications:

• Radiologists and clinicians should consider paracoccidioidomycosis in the differential diagnosis of pediatric bone lesions with permeative destruction, especially in endemic areas.
• Prompt laboratory identification of the causative fungus, Paracoccidioides brasiliensis, is critical for appropriate management.
• This case contributes to the understanding of the diverse clinical spectrum of paracoccidioidomycosis in children.
