RESUMEN
Background: Nodular lymphoid hyperplasia of the gastrointestinal tract, recurrent acute pulmonary infections and autoimmune disease are well-recognized complications of common variable immunodeficiency
Aim: We aimed to focus on clinical presentation and differential diagnosis of diffuse nodular lymphoid and hyperplasia of the gastrointestinal tract coexisting with hypogammaglobulinemia
Case-report: We report the case of nodular lymphoid hyperplasia associated with pernicious anaemia in a young man with hypogammaglobulinemia and a long history of pulmonary infections
Conclusion: The considerable point was a mismatch primary clinical diagnosis of familial adenomatous polyposis, due to prominent polyplike endoscopic appearance of the lesions throughout the digestive tract
