Zusammenfassung: | Florid reactive follicular hyperplasia (FRFH) of the enlarged lymph node in elderly patients requiring biopsy is a relatively uncommon phenomenon as compared with younger age groups. We experienced 23 patients, aged 60 years or more, from whom the biopsied lymph node specimens histologically showed inappropriate FRFH for their age, in the period between 1982 and 1996. These cases were morphologically subdivided into three groups, FRFH with interfollicular plasmacytosis, that with progressive transformation of germinal center, and FRFH without additional specific findings. FRFH with interfollicular plasmacytosis were observed in 11 cases, all of whom were accompanied with several immunological . abnormalities (six with rheumatoid arthritis, three with multicentric Castleman's disease and one each with myoepithelial sialoadenitis and autoimmune hemolytic anemia). Three men with uncertain etiology exhibited an unusual histology of progressive transformed germinal centers which were clinically characterized by a bulky neck mass. Among the nine cases with nonspecific FRFH, only four had a specific etiology (one each with adult onset Still's disease, chronic sinusitis, Epstein-Barn virus infection and infectious lateral cervical cyst), while the other five with unknown etiology showed abnormal laboratory findings suggestive of an abnormal humoral immune response, i.e. hypergammaglobulinemia and seropositivities for some autoantibodies. None of our patients developed malignant lymphoma during the follow-up period. Of note, 16 (70%) of the 23 cases were found to be associated with various types of imbalances of the immune system, some of which appeared to be currently ill-defined as clinicopathological entities that were simply categorized as autoimmune disease. |
