Duodenitis con cuerpos de Russell. Revisión de la entidad y posibles asociaciones más allá del H. pylori

Abstract

Plasma cells known as “Mott cells” present non-secretable accumulations of immunoglobulins called “Russell bodies”. Its presence is related to hematological neoplasms, but it can appear in chronic inflammatory processes. The most common occurrence within the digestive tract is the gastric antrum associated with H. pylori infection. Our patient is added the rare extragastric cases where the association with H. pylori is inconsistent. We have found a frequent appearance of lower digestive and urological neoplasms in relation to these cases, justified by the expression of circulating cytokines in the tumor area that lead to the overactivation of plasma cells. This possible association could lead us to know data about the tumor environment and serve us for early diagnosis or future therapeutic targets.
