Abstract:
BACKGROUND:Primary cutaneous cryptococcosis is an uncommon infectious disease caused by Cryptococcus neoformans or Cryptococcus gattii affecting immunosuppressed as well as immunocompetent patients. It is often misdiagnosed as it may mimic other cutaneous diseases. MATERIALS AND METHODS:We report a series of cases diagnosed from 2005 to 2010 in two general hospitals. The diagnosis in all patients was made on the basis of histopathology and culture. Phenoloxidase and canavanine-glycine-bromothymol blue tests were used in order to identify the Cryptococcus species. Systematic investigation ruled out the systemic involvement in every case. RESULTS:Eleven patients, 81.8% male, were diagnosed during this study. The immunosuppression status was identified in 54.5% of patients, and all of them were under corticosteroid therapy due to a variable set of diseases. All patients presented with circumscribed lesions on their upper limbs. Most lesions showed an infiltrative or tumoral aspect with up to 40 cm diameter. Fluconazole, up to 400 mg/daily, was the main therapeutic regimen and proved to be efficient. CONCLUSIONS:Primary cutaneous cryptococcosis has been diagnosed in both immunosuppressed and immunocompetent patients. Its peculiar clinical aspect could facilitate early diagnosis. Culture and biochemical tests should be performed in order to define the species involved.
