Candida hepatitis. Histopathologic diagnosis.
Candida hepatitis, usually a manifestation of disseminated candidiasis in immunocompromised patients, is difficult to diagnose antemortem. We studied six patients with proven hepatic candidiasis to assess features helpful in deriving a correct diagnosis. Five patients were immunosuppressed as a result for treatment for leukemia; one was immunosuppressed due to renal transplantation. All had sustained fevers greater than 101 degrees F, elevated alkaline phosphatase levels, and multiple hepatic and splenic defects--presumably abscesses--on abdominal CT scan. Twelve liver biopsies (nine needle, three wedge) were examined. Biopsies from four patients contained identifiable Candida organisms within suppurative granulomas; a biopsy from a fifth patient grew Candida albicans in cultures. In the sixth patient, the first biopsy was culture positive for Candida albicans, and the second biopsy, a fine-needle aspirate, contained Candida organisms and purulent material. In all of the nondiagnostic biopsies, as well as in regions of the diagnostic biopsies around the suppurative granulomas, mass-associated obstructive changes were noted. These included pericentral sinusoidal dilatation and cholestatic inflammation characterized by periportal ductular proliferation with surrounding neutrophils and edema. We conclude that in the appropriate clinical setting, these mass-associated histologic findings are suggestive of adjacent Candida abscesses. Definite diagnosis requires either the identification of Candida organisms within inflammatory hepatic lesions or positive culture of Candida from the liver biopsy.
