Paecilomyces lilacinus is a little-known mold that causes rare cases of invasive infections in humans regardless of their immune status. We present a unique case in an immunocompromised host with olecranon bursitis because of multidrug-resistant P. lilacinus treated with systemic ketoconazole therapy and surgical debridement. Recognition of this fungus is difficult initially because of its appearance, which can be confused with that of other fungi. Once this organism has been identified, it is recommended that antifungal susceptibility testing be obtained to guide appropriate therapy. Combination of therapeutic modalities requires case-by-case assessment. Surgical debridement and removal of prosthesis may be indicated. Although P. lilacinus can be a laboratory contaminant, in our case, causation was established as the organism grew in repeated cultures, sufficient to confirm a fungal origin for his bursitis.
