Abstract
INTRODUCTION AND IMPORTANCE: Ganglioneuroma is a rare benign neuroblastic tumor originating from sympathetic ganglion cells in the peripheral nervous system. It is often incidentally discovered during imaging studies and primarily affects children and young adults. CASE PRESENTATION: We present a case report of a 21-year-old female diagnosed with non-Hodgkin lymphoma who had an abdominal mass incidentally detected during imaging, Initially mistaken for lymphoma in the setting of the primary diagnose. After the chemotherapy for the lymphoma, the mass did not response to the treatment, so the mass was surgically excised, and histopathological examination confirmed the diagnosis of ganglioneuroma. The patient responded well to treatment for lymphoma and remains in good condition without signs of recurrence. CLINICAL DISCUSSION: To the best of our knowledge, this is the first case that describes an association between an intraabdominal ganglioneuroma and non-Hodgkin's lymphoma. CONCLUSION: This case highlights the importance of considering ganglioneuroma as a differential diagnosis when evaluating abdominal masses in patients with lymphoma.
