Methods: We queried 118 GI tract schwannomas reviewed radiologic findings, intraoperative electronic medical records all cases for enlarged lymph nodes. Results: Location tumors included 85 gastric (72%), 11 colonic (9.3%), 7 esophageal (5.9%), pancreatic (2.5%), hepatic (0.8%), mesenteric (9.3%). The size ranged from 0.2 cm (mean 3.8 cm). Histologically, 70.3% showed a ranging thickness 0.3 6 mm 1.6 mm). was significantly more frequent (78.8%) followed by (72.7%), (57.1%) rare other locations ( p = 0.001). Of 106 which clinical or data available for, 76 (71.7%) presence significant correlation with < 0.001) nodes 0.002). Conclusions: A is frequently seen correlates well However, subset (29.7%), not present warranting continued need caution preoperative postoperative pathologic diagnoses.
