Cryptococcus neoformans is an ubiquitously occurring encapsulated fungus that is commonly found in the environment. It is also an opportunistic pathogen that has potential to cause systemic fungal infection, predominantly in the immunocompromised host with cell-mediated immunological defects. Cryptococcal tenosynovitis is an extremely rare condition, with only a few cases previously documented in the literature. We report a case of chronic suppurative cryptococcal extensor tenosynovitis in a patient with Castleman's disease who was successfully managed with surgical debridement and antifungal therapy.
