Insights
Invasive fungal infections are rising in children due to increased survival rates and treatments like chemotherapy and transplants. This case highlights a rare fungal infection in an immunosuppressed infant.
Area of Science:
- Pediatric Infectious Diseases
- Mycology
- Neonatology
Background:
- Invasive fungal infections (IFIs) are increasingly prevalent in pediatric populations.
- Factors contributing to this rise include advances in neonatal care, increased use of immunosuppressive therapies (chemotherapy, stem cell, and solid organ transplantation), and improved survival of immunocompromised children.
Observation:
- A case of cutaneous Exserohilum rostratum infection in an immunosuppressed neonate is presented.
- Exserohilum rostratum is a dematiaceous fungus typically found in soil and plant material.
Findings:
- The neonate developed a localized cutaneous infection caused by Exserohilum rostratum.
- This represents a rare manifestation of this fungus in a pediatric patient, particularly in a neonate.
Implications:
- This case underscores the importance of considering rare fungal pathogens in the differential diagnosis of infections in immunocompromised neonates.
- Early recognition and appropriate antifungal treatment are crucial for managing invasive fungal infections in this vulnerable population.
- Further research into the epidemiology and management of Exserohilum rostratum infections in neonates may be warranted.
Abstract:
Invasive fungal infections in children have increased in recent years, coinciding with greater survival of preterm neonates and children with immunodeficiencies, more intense chemotherapy regimens, and greater use of stem cell and solid organ transplantation. We describe a case of an immunosuppressed neonate who developed cutaneous Exserohilum rostratum infection.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
