Oral cryptococcosis in a patient with AIDS. A case report.

A 59-year-old Caucasian male patient with AIDS is described who presented with an oral lesion of cryptococcosis. The gingival ulceration was the only detectable lesion of cryptococcosis. Diagnosis was established by histopathologic findings from biopsy and detection of serum cryptococcal antigen. The patient was treated with amphotericin B and flucytosine. After four weeks of therapy cryptococcal antigen turned negative. The oral ulceration diminished in size, but an inflammatory tissue reaction persisted.
