A rare case of Cryptococcus luteolus-related tenosynovitis.

A 68-year-old male with type II diabetes mellitus presented with a nodule over the metacarpophalangeal joint of his right second finger after being spurred on the hand by a domestic turkey 2 weeks prior to onset of clinical symptoms. He was diagnosed with cryptococcal tenosynovitis caused by Cryptococcus luteolus identified by DNA sequencing. Complete clinical resolution was achieved with synovectomy and debridement followed by 1 year of fluconazole 800 mg daily.
