Fibrin ring granuloma is characterized by a fibrinous ring surrounding a central fat vacuole. It has been found in the liver and bone marrow of patients with Q fever, and occasionally with visceral leishmaniasis, cytomegalovirus, Epstein-Barr virus, Staphylococcus epidermidis infections, Hodgkin's lymphoma, and hypersensitivity to allopurinol. We describe a case of serologically confirmed viral hepatitis A with this lesion in the liver biopsy. A false positive anti-hepatitis A virus IgM result has been excluded. This is, to our knowledge, the second reported case of type A hepatitis with hepatic fibrin ring granulomas. It confirms that hepatitis A should be included in the differential diagnosis of this lesion.

Nonmalignant lymphoid tissue and tissue from patients with nodular sclerosis, Hodgkin's disease, and large cell lymphocytic lymphoma was examined by immunohistochemical techniques for the occurrence in situ of components of coagulation and fibrinolysis reaction pathways. Staining for material interpreted as fibrinogen was observed in abundance in both malignant and reactive lymphoid tissue. Fibrin also occurred to a variable extent but focally in all tissues. Components of coagulation pathways, including tissue factor, factor VII, factor X, and factor XIII ("a" subunit), were restricted to tissue macrophages. Double-labeling techniques revealed fibrin in direct apposition to tissue macrophages. We conclude that fibrinogen and fibrin occur in both benign and malignant lymphoid tissue and that the transformation of fibrinogen to fibrin is attributable to macrophage-initiated thrombin formation. We postulate that both systemic and local hypercoagulability associated with these disorders may be attributable to macrophage activation resulting in expression of procoagulant activity.

Fibrin deposits were observed in the involved lymph nodes and/or spleens of 15 patients with Hodgkin's disease by specific immunofluorescence and by electron microscopy. Two basic patterns of fibrin deposition were observed: 1) intercellular deposits, chiefly associated with nonneoplastic-appearing lymphoid cells and 2) deposits associated with the collagen fibers of young connective tissue. In addition, coarse fibrin deposits were observed in areas of necrosis, presumably a non-specific finding. Fibronectin was also observed in intercellular areas, but staining was less intense than for fibrin. Fibrin deposits were also observed in 3 of 6 cases of non-Hodgkin's lymphoma, indicating that the finding is not an exclusive feature of Hodgkin's disease. The pathogenesis and possible significance of fibrin deposition in Hodgkin's disease are related to earlier observations of activation of the coagulation system on neoplasia and cell-mediated immunity and to the possible role of fibrin, fibronectin, and their breakdown products in angiogenesis and fibroplasia.
