NEUROENDOCRINE TUMOR IN A CHILD WITH COMMON VARIABLE IMMUNODEFICIENCY

Area of Science:

• Pediatric Immunology
• Gastroenterology
• Oncology

Background:

• Common Variable Immunodeficiency (CVID) is a primary immunodeficiency characterized by hypogammaglobulinemia.
• Adults with CVID have an increased risk of gastric tumors.
• The association between CVID and neuroendocrine tumors in children is not well-established.

Observation:

• A pediatric case of CVID presented with recurrent pneumonias from one year of age.
• At eight years, the patient developed epigastric pain, progressing to chronic diarrhea and weight loss by age ten.
• A neuroendocrine tumor was diagnosed, leading to rapid disease progression.

Findings:

• This is the first reported case of a neuroendocrine tumor in a pediatric patient with Common Variable Immunodeficiency.
• The patient's gastrointestinal symptoms were indicative of a developing neoplasm.
• The tumor exhibited rapid progression despite treatment.

Implications:

• Early investigation for digestive neoplasms should be considered in pediatric patients with CVID presenting with gastrointestinal symptoms.
• Recognizing this association may improve diagnostic timelines and patient prognosis.
• Further research is needed to understand the link between CVID and neuroendocrine tumors in children.
