[Aspergillosis of the antrum].

Aspergillus falls into the class of hyphae-forming molds and is ubiquitous. It is known as a facultatively pathogenic opportunist. It is incorporated by breathing in spores from the air and develops its pathogenicity only in predisposed subjects with a weakened systemic or local defense mechanism. While systemic mycosis involves a weakening of the defense condition by an underlying disease, immune suppressant therapy, metabolic disorder or the like, isolated antral affections usually appear in otherwise healthy subjects. Our observations in one case are presented.
