Perifollicular concentric granulomas: A clue to IgG4-related lymphadenopathy.
A 69-year-old with well-controlled HIV was evaluated for persistent cough, in the context of years of fatigue and influenza A infection 6 months prior. Chest CT and PET scans were notable for adenopathy concerning for a lymphoproliferative disorder. Radiologic studies also showed diffuse FDG uptake in the prostate, consistent with prostatitis. Axillary lymph node biopsy showed follicular and paracortical hyperplasia, and few germinal centers showed perifollicular non-necrotizing granulomas. Immunohistochemical staining demonstrated a predominance of IgG4 positive plasma cells. Serum protein electrophoresis (SPEP) and immunosubtraction showed a board-domed peak pattern suggestive of possible monoclonality. Serum IgG4 levels were elevated, and the patient was diagnosed with IgG4-related disease (IgG4-RD). This case highlights morphologic and SPEP patterns that can aid in supporting a diagnosis of IgG4-RD.
期刊介绍：
The Journal of Hematopathology aims at providing pathologists with a special interest in hematopathology with all the information needed to perform modern pathology in evaluating lymphoid tissues and bone marrow. To this end the journal publishes reviews, editorials, comments, original papers, guidelines and protocols, papers on ancillary techniques, and occasional case reports in the fields of the pathology, molecular biology, and clinical features of diseases of the hematopoietic system.
The journal is the unique reference point for all pathologists with an interest in hematopathology. Molecular biologists involved in the expanding field of molecular diagnostics and research on lymphomas and leukemia benefit from the journal, too. Furthermore, the journal is of major interest for hematologists dealing with patients suffering from lymphomas, leukemias, and other diseases.
The journal is unique in its true international character. Especially in the field of hematopathology it is clear that there are huge geographical variations in incidence of diseases. This is not only locally relevant, but due to globalization, relevant for all those involved in the management of patients.
