Phaeohyphomycosis refers to infections of skin, subcutaneous tissues, and internal organs caused by dematiaceous (melanized) fungi that produce pigmented hyphae and/or yeast-like cells in culture and frequently in the infected tissue. Species of several genera of dematiaceous fungi, e.g., Alternaria, Bipolaris, Curvularia, Cladophialophora, Cladosporium, Exophiala, Exserohilum, Phaeoacremonium, or Phialophora, are commonly reported as agents of phaeohyphomycosis (4, 11). Wallemia sebi, another dematiaceous anamorphic fungus and a common causative agent of farmer's lung disease (10, 13-15, 18), is a rarely known agent of human infection reported in earlier literature between 1909 and 1950 (2, 3, 6, 9). Thus, it is considered of interest to report here a case of subcutaneous phaeohyphomycosis caused by W. sebi.
The class Wallemiomycetes and the order Wallemiales have recently been erected and considered as a sister group of the Basidiomycota to accommodate the single genus Wallemia (8, 19). This genus comprises three xerophilic species, which are phenotypically distinguished mainly by the size range of conidia and by the degree of their xerophily (19). Wallemia sebi is the only species capable of growth on media such as malt extract agar without additional solutes (NaCl, glucose) and shows the smallest conidia (1.5- to 2.5-μm diameter). It is the only species of Wallemia that has been involved in human infections. 781b155fdc
