We present a case of tenosynovitis-arthritis caused by Pseudallescheri
a boydii. The patient was a 63-year-old person with a chronic lymphocy
tic leukaemia and a haemolytic anaemia since 9 years. He was treated w
ith cytostatics and corticosteroids. The fungal infection started with
a skin injury al the level of the left carpal bone that slowly progre
ssed into a cystic swelling. The patient, who developed the infection
under a low prophylactic dose of 100 mg fluconazole daily, was success
fully treated with a higher dose of 400 mg daily. This is the first ca
se of successful treatment with fluconazole in a case of pseudallesche
riasis.
