Prototheca wickerhamii prepatellar bursitis in an immunocompetent woman: A case report

Prototheca wickerhamii is a rare cause of septic prepatellar bursitis. We report a patient who had no apparent immunodeficiency developed P. wickerhamii prepatellar bursitis following intra-bursal corticosteroid injection. Clinical manifestations could not distinguish Prototheca bursitis from septic bursitis caused by other pathogens. Bursal fluid aspiration sent for direct microscopic examination and cultures could give an early diagnosis. Systemic antifungal therapy with complete surgical excision of infected bursa provided a good outcome. (C) 2019 Published by Elsevier Masson SAS.
