| Popis: | Plasma cell granuloma (PCG) is a pseudotumor of unknown origin. It is frequently accompanied by acute-phase clinical and biological signs that resume after complete surgical removal, suggesting production of soluble mediators. We therefore investigated the role of cytokines in a previously healthy 10-year-old boy with a PCG of the lung and systemic symptoms. In this case, very high serum levels of interleukin-1 beta (IL-1 beta) and interleukin-6 (IL-6) were found before tumor excision, associated with inflammatory signs including major hyper-gamma-globulinemia. Pathologic analysis of the tumor showed an accumulation of fibroblasts and plasma cells producing immunoglobulins. Local production of IL-1 beta and IL-6 could be demonstrated at the messenger RNA (mRNA) level by the reverse transcriptase polymerase chain reaction and could be attributed to inflammatory cells by in situ hybridization and immunohistochemistry, whereas plasma cells exhibited membrane expression of the IL-6 receptor. Postsurgery follow-up showed rapid normalization of serum IL-1 beta and IL-6, whereas inflammatory protein levels decreased. This confirms the local production of cytokine within the PCG and raises the question of whether a dysregulation of cytokine production initiates the disease. |
