Abstract

We report a rare case of fungemia due to Exophiala (Wangiella) dermatitidis in a 4-month-old female infant who was admitted to an intensive care unit with sudden infant death syndrome (SIDS). E. dermatitidiswas repeatedly isolated from blood cultures (on the 28th and 32nd day of hospitalization) of the patient, who died on the 44th day of hospitalization. The fungus was identified by its morphological characteristics and DNA sequencing of both the D1/D2 domain and the ITS region of rDNA. To our knowledge, this is the first reported case of E. dermatitidis fungemia in Korea.

Keywords: Exophiala (Wangiella) dermatitidis; Fungemia; ITS; Sequencing

Fig. 2
Microscopically, septate, and pale olivaceous hyphae and black yeast synanarmorphs were found. Conidiogenous cells were cylindrical, with rounded apeces producing one-celled conidia. Round to ovoid, pale brown conidia accumulated in balls or slipped down the side of conidiophores (Lactophenol cotton blue stain, ×400).
