    Gross lesions characterized by swollen livers and spleens accompanied by diffuse white miliary spots, which resembled those of Marek's disease, were detected in two flocks of local meat-type chickens at a Japanese poultry processing plant in June and August 2010. The microscopic examinations revealed proliferative foci consisting of spindle or polymorphic cells in the interstitium of livers, splenic follicles and the interstitium of kidneys. These cells were positive immunohistochemically with Iba1 antibody, indicating they were histiocytic cells. Read More

    Department of Internal Medicine, Saint Joseph Hospital, 2900 N. Lake Shore, Chicago, IL 60657, USA.
    Multicentric reticulohistiocytosis is a rare multisystem disorder of unknown etiology that is characterized by erosive polyarthritis and papulonodular lesions on the skin, mucous membranes, and internal organs. We report the case of a 54-year-old female who was misdiagnosed as having rheumatoid arthritis and underwent numerous joint replacement surgeries for progressively destructive arthritis in her hands, shoulders, hips, and knees. The patient finally received a diagnosis of multicentric reticulohistiocytosis after histopathological examination of the patient's left knee arthroplasty which revealed a diffuse histiocytic infiltrate, multinucleated giant cells, and finely granulated eosinophilic cytoplasm with a ground-glass appearance.

    Multicentric reticulohistiocytosis: a rare yet challenging disease.
    Clin Rev Allergy Immunol 2013 Oct;45(2):281-9
    Division of Rheumatology, Allergy and Clinical Immunology, University of California at Davis School of Medicine, 451 Health Sciences Drive, Suite 6510, Davis, CA, 95616, USA.
    Multicentric reticulohistiocytosis (MRH) is a rare systemic inflammatory granulomatous disease that primarily manifests clinically with severe erosive arthritis and widespread papulonodular skin lesions but can involve multiple other organ systems. Despite the fact that this condition can become aggressive, debilitating as well as deforming with significant detrimental consequences, the etiology of this disease remains poorly understood. Moreover, the fact that MRH is such an uncommon disease has created an obstacle in the path of adequate clinical trials that are needed for better understanding of this phenomenon and for the development of treatment options for this patient population.
