[First Report of Intraorbital Abscess Caused by Candida allociferrii and Specific PCR for Differentiating Stephanoascus ciferrii Complex Species].

We present a rare case of intraorbital abscess caused by Candida allociferrii, which was described as a new species of Stephanoascus ciferrii complex in 2002, in a patient after enucleation of choroidal melanoma. This strain showed resistance to itraconazole, and fluconazole. After debridement and topical use of amphotericin B, his wound abscess was disappeared.

[Isolation of the yeast-like fungus Stephanoascus ciferrii by culturing the aural discharge of a patient with intractable otitis media. Case report].

As longer lives have become possible due to advances in medical technology and diagnostic technology in recent years, weakly toxic fungus have been emerging as causative agents of opportunistic infections, primarily in high-risk groups. We report a case in which the yeast-like fungus Stephanoascus ciferii, which has morphological characteristics that differ from those of the more common Candida species, was isolated by culturing the aural discharge of a patient with intractable otitis media. Drug susceptibility testing showed that it was resistant to fluconazole, flucytosine, and itraconazole, suggesting that it is a species that has a strong tendency to become resistant.
