title: Hepatic fibrin-ring granulomas: a clinicopathologic study of 23 patients.
abstract: Twenty-three patients with characteristic hepatic fibrin-ring granulomas were studied. Q fever accounted for 10 cases (43%), visceral leishmaniasis for five cases (22%), boutonneuse fever for two cases (9%), and toxoplasmosis, Hodgkin's disease, and allopurinol hypersensitivity for one case each (4%). The etiology remained undetermined in three cases (13%). This report broadens the range of etiologies of hepatic fibrin-ring granulomas to include boutonneuse fever and toxoplasmosis in the differential diagnosis of ring granulomas, and it could serve as a guideline to the clinician and pathologist for the most frequent categories of disease associated with this morphologic pattern.
