ARTICLE HIGHLIGHTS
Research background
Abdominal neurogenic tumors constitute an extremely rare yet important group of intraabdominal soft tissue lesions.
Research motivation
The current knowledge regarding abdominal neurogenic tumors is limited. A more detailed understanding of their clinical and pathological characteristics will benefit diagnosis as well as management of these tumors and their disease manifestations.
Research objectives
We aimed to delineate the comprehensive clinical, radiologic and histopathological characteristics of intraabdominal neurogenic tumors.
Research methods
We reviewed a nationwide referral center’s 15 years’ worth of biobank data, collecting clinical, radiologic and clinical variables of all patients during that period. In addition, we obtained the archived paraffin-embedded specimens for each of the 19 cases identified and re-evaluated the histopathologic and immunohistochemical features.
Research results
Nineteen cases of tumors were identified from our database for the 15-year period. The most common lesion was schwannoma (n = 12), followed by diffuse submucosal neurofibromatosis, ganglioneuromas, and malignant peripheral sheath nerve tumors (n = 2 each), and mucosal Schwann cell hamartoma (n = 1).
Research conclusions
Intraabdominal neurogenic tumors have excellent clinical outcome. However, there are nuances in their radiologic, endoscopic and histologic diagnoses.
Research perspectives
Multi-institutional studies with larger study populations are merited.
