ABSTRACT
We describe a case of a 57-year-old woman with a history of gastric MALT lymphoma and interstitial nephritis attributed to chemotherapy. In the study of chronic diarrhea, we found an atrophic pancreas, with elastase deficiency. Autoimmune pancreatitis is suspected. A significant elevation of serum IgG4 was observed. With these data, a review of the renal biopsy performed 10 months earlier was carried out. Immunohistochemistry reveals a significant number of IgG4-producing plasma cells. In the lungs, the patient has nodules, adenopaties and infiltrates. The diagnosis we arrived at is IgG4-related disease. (AU)
RESUMEN
Se presenta el caso de una mujer de 57 años con antecedentes de linfoma MALT gástrico y nefritis intersticial atribuida a la quimioterapia. En el estudio de diarrea crónica encontramos un páncreas atrófico, con deficiencia de elastasa. Se sospecha pancreatitis autoinmune. Se comprueba una elevación importante de IgG4 sérica. Con estos datos, se procede a la revisión de la biopsia renal realizada 10 meses antes. La inmunohistoquímica revela un número significativo de células plasmáticas productoras de IgG4. En los pulmones, la paciente tiene nódulos, adenopatías e infiltrados. El diagnóstico al que llegamos es Enfermedad relacionada con IgG4. (AU)
