Abstract
We isolated a black yeast strain from nodules on the left buttock of a 71-year-old male which were histologically confirmed as Bowen's disease. The isolate was seen histologically as hyphae in the upper layer of the crust of a Bowen's lesion, and was identified as Exophiala jeanselmei by slide culture and scanning electrom microscopic study.
To our knowledge, this is the first report of a saprophytic growth of E. jeanselmei on a pre-existing skin lesion.
We consider that this case indicates an intermediate step between saprophytic growth and infection.
