Article Synopsis
  • Phaeohyphomycosis is a serious infection caused by pigmented fungi, particularly affecting immunocompromised children, with a lower mortality rate compared to adults (22.3% in children vs. 79% in adults).
  • A review of 130 pediatric cases showed common risk factors like hematologic malignancies, neutropenia, and steroid therapy, with localized infections being the most prevalent type (61.5%).
  • Most cases were treated successfully with antifungal therapy (87%), but the mortality rate varied significantly based on the infection site and patient conditions, indicating a need for more research.

Background: Exserohilum species are environmental moulds that can cause skin infection and sinusitis in both normal and immunosuppressed children. This study reviews paediatric cases of Exserohilum infection in Queensland, Australia, to identify the spectrum of disease and its clinical course.

Methods: All culture-positive samples of Exserohilum species in children <18 years of age were identified from the Queensland Health Laboratory database (April 2003-April 2018).

Transplant recipients are at a high risk for developing invasive fungal infections. The agents of phaeohyphomycosis are environmental molds found worldwide, and they cause a broad spectrum of disease including skin and subcutaneous lesions, pneumonia, central nervous system disease, fungemia, and disseminated disease. Using data from the Transplant Associated Infection Surveillance Network (TRANSNET), we evaluated patients with proven and probable phaeohyphomycosis.

Deep cutaneous fungal infections in immunocompromised children.

J Am Acad Dermatol

November 2009

Division of Dermatology, CHU Sainte-Justine, Montreal, Quebec, Canada.

Background: Life-threatening infections from ubiquitous fungi are becoming more prevalent in adults and children because of the increased use of immunosuppressive agents and broad-spectrum anti-infective drugs. Extremely low birth weight premature neonates and patients with a disrupted epidermal barrier are also at increased risk. Lethality is high, particularly with delayed diagnosis.
