[Disseminated fusariosis in a patient with acute lymphoblastic leukaemia]

Area of Science:

• Medical Mycology
• Hematology
• Infectious Diseases

Background:

• Invasive mould infections (IMIs) pose a significant threat to immunocompromised individuals, particularly those with hematologic malignancies.
• Aspergillus species are the most common culprits, but non-Aspergillus moulds are increasingly recognized.
• High-risk patients face a 10-20% incidence of IMIs with over 50% mortality.

Observation:

• A 74-year-old woman with acute lymphoblastic leukaemia (ALL) developed a disseminated mould infection during induction chemotherapy.
• The causative agent was identified as Fusarium solani, a rare cause of invasive disease in this population.
• The patient's presentation occurred despite standard prophylactic measures.

Findings:

• This case details a rare instance of disseminated Fusarium solani infection in a patient undergoing chemotherapy for ALL.
• The study discusses the specific pathogenesis and clinical manifestations of invasive fusariosis.
• Treatment strategies and challenges for this rare fungal infection are explored.

Implications:

• Highlights the importance of considering non-Aspergillus moulds in the differential diagnosis of IMIs in immunocompromised patients.
• Underscores the need for prompt diagnosis and tailored treatment approaches for invasive fusariosis.
• May inform the development of improved antifungal strategies and prophylaxis for high-risk hematology patients.
