Primary retroperitoneal abscess caused by Candida glabrata.

Clinically, retroperitoneal abscesses present insidiously and the diagnosis may be delayed. This, with inadequate drainage, may result in increased morbidity and mortality. Most cases result from a renal or gastrointestinal process, but in a small number of patients there is no identifiable source and the abscess is designated as "primary." Most retroperitoneal abscesses are polymicrobial, and cultures often reveal organisms such as Proteus mirabilis, Staphylococcus species, Peptostreptococcus, Enterococcus, Enterobacter, Escherichia coli and Bacteroides species. Fungal causes appear to be very rare, and in this study, a case of a patient with primary Candida glabrata retroperitoneal abscess is reported.
