Síndrome de Good, una causa infrecuente de diarrea crónica

Abstract

Chronic diarrhea is a frequent cause of consultation in daily clinical practice. There are multiple diagnostic algorithms that allow a staggered approach to the most frequent pathologies, leaving out some lesser-known ones. This article reports the case of a 66-year-old female patient with a history of arterial hypertension, dyslipidemia and resected AB thymoma and a history of chronic diarrhea of 8 weeks of evolution. The etiological study ruled out infectious causes, celiac disease and negative viral serology. Due to a history of thymoma, immunoglobulin count was performed, showing severe pan-hypogammaglobulinemia. Good's Syndrome is the combination of thymoma and hypogammaglobulinemia, where patients may present with diarrhea secondary to immunodeficiency. Hypogammaglobulinemia associated with the presence of a thymoma is a rare cause but widely described in the literature as Good's Syndrome. Therefore, it seems relevant to describe a case, its approach and subsequent management.
