Conidiobolomycosis in relapsed acute lymphoblastic leukemia

Area of Science:

• Mycology
• Hematology
• Pediatric Oncology

Background:

• Invasive fungal infections (IFIs) are a leading cause of death in children with hematological malignancies.
• Fungal pathogens beyond Candida and Aspergillus are increasingly recognized as significant threats.
• Emerging fungal infections present unique challenges in epidemiology and treatment for immunocompromised hosts.

Observation:

• This report details the isolation of Conidiobolus coronatus, a zygomycetes fungus, from a pediatric patient.
• The patient was diagnosed with acute lymphoblastic leukemia and presented with an invasive fungal infection.
• Conidiobolus typically causes sino-respiratory infections but can be angioinvasive and disseminate.

Findings:

• Conidiobolus coronatus, a rare zygomycetes, was identified as the causative agent of invasive fungal infection.
• The infection occurred in a pediatric patient with acute lymphoblastic leukemia, a high-risk immunocompromised state.
• The angioinvasive potential and dissemination risk of Conidiobolus were observed in this case.

Implications:

• This case underscores the importance of considering rare fungal pathogens in immunocompromised children.
• There is a critical need for further research into the diagnosis and management of Conidiobolus infections.
• Establishing consensus on effective antifungal treatment strategies for Conidiobolus is essential for improving patient outcomes.
