Ulcerated plaque under a ruby ring in an immunosuppressed patient.

ABSTRACT

We report a primary inoculation fungal infection in a 76-year-old man with acute myeloid leukemia. The patient presented with a painful red plaque located where he routinely wore a ruby ring. Histopathology revealed multiple branching septate hyphae. Cultures confirmed Fusarium and Candida parapsilosis infection. A short discussion of these organisms follows.
