Dermatophytosis in patients with chronic mucocutaneous candidiasis.

We review the association of concurrent dermatophytic infections in patients with chronic mucocutaneous candidiasis and add twelve new patients to the seventeen previously reported ones. In sixty patients with chronic mucocutaneous candidiasis studied at the National Institutes of Health (NIH), twelve (20%) also had significant local or diffuse dermatophytosis. A comparison between candidiasis patients with and without dermatophytosis revealed no significant differences in their distribution within the various clinical syndromes of chronic mucocutaneous candidiasis nor in the immunologic responses that were tested. Failure to recognize coexistent dermatophytosis in candidiasis patients may lead to unsatisfactory responses to treatment.
