title: Extensive and deep dermatophytosis caused by Trichophyton mentagrophytes var. interdigitalis in an HIV-1 positive patient.
abstract: BACKGROUND
  Cutaneous infections are common in HIV-1 positive patients and are usually severe, recurrent, and caused by microorganisms that are unusual in immunocompetent patients.
  
  
  OBJECTIVE
  We report a case of an HIV-1-positive 23-year-old male, with a history of intravenous drug use, in stage C-II (CDC '86), with a CD4 lymphocyte count of 335 cells/mm3. He had multiple, large erythematous, circinate and pustular plaques on his abdomen, back, arms and legs.
  
  
  RESULTS
  We isolated Trichophyton mentagrophytes var. interdigitalis from the lesions. The biopsy showed suppurative deep dermatophytosis and folliculitis. The patient satisfactorily responded to itraconazole (100 mg/d for 14 days).
  
  
  CONCLUSIONS
  This is the first reported case of deep dermatophytosis caused by T. mentagrophytes in an HIV-positive patient.
