診断に難渋したCandida pαrapsilosisによる真菌性腱鞘滑膜炎の一例

Abstract

A 59-year-old woman presented with swelling of the distal interphalangeal (DIP) joint to base of the distal phalanx of the left middle finger for more than 2 years. The patient was suspected to have infectious tenosynovitis, but the causative microorganism could not be identified. The patient was treated diagnostically with antimicrobial agents，but the condition worsened again during treatment, and Candida parapsilosis was detected in the joint fluid culture. Although it took some time to make a definite diagnosis due to prior antimicrobial therapy at another hospital and failure to promptly perform a third debridement, a diagnosis of fungal tenosynovitis was finally made based on culture and histopathological findings.
