Paecilomyces lilacinus septic olecranon bursitis in an immunocompetent host.

Paecilomyces lilacinus is a filamentous fungus that is a rare cause of infection in immunocompromised human hosts. We present a case of lilacinus septic olecranon bursitis in an otherwise healthy 78-year-old male. This patient's case was complicated by wound breakdown after bursectomy and appropriate anti-fungal treatment, requiring a local soft tissue rearrangement. This case demonstrates the need for appropriate and timely medical and surgical treatment in infections involving lilacinus, which are not isolated solely to systemically immunocompromised and medically-ill patient populations. In cases where the patient is systemically immumocompromised or has been rendered locally immunocompromised, it is essential to obtain a full culture work-up, including fungi.
