Gastric Mass

Gastric schwannomas are rare mesenchymal tumors that arise from the nerve plexus of gut wall. They present with nonspecific symptoms and are often detected incidentally. Preoperative investigation is not pathognomic and many are therefore misdiagnosed as gastrointestinal stromal tumors. We report a rare case of a 37-year old woman who underwent laparotomy for complex bilateral ovarian cyst with resection of gastric-gastrointestinal stromal tumor preoperatively, but confirmed to have a gastric schwannomas postoperatively. This case underscores the differential diagnosis of submucosal, exophytic gastric mass as schwannoma.

Microscopic Findings

Introduction. Schwannomas are rare benign tumors of the gastrointestinal tract. Despite the differences in features of schwannomas located in the stomach as opposed to peripheral or soft tissue schwannomas, their immunohistochemical characteristics are the same. We present a case of a 14-month-old boy with a gastric tumor who underwent a combined laparoscopic-endoscopic resection surgery, followed by gastric schwannoma diagnosis. Case outline. The patient was admitted to our pediatric hospital with a fever of unknown origin. Endoscopy, performed after recurrent hematemesis, revealed an ulcer in the gastric antrum. At the four-week follow-up, gastroscopic and microscopic findings were normal. Two weeks later, a flank mass in the antrum was detected by an ultrasound examination. A new gastroscopy and CT scan confirmed the presence of a tumor-like mass, 5 cm in diameter. A combined laparoscopic-endoscopic polypectomy was performed with a necessary conversion for complete resection of tumor. The initial histological findings were consistent with a gastrointestinal stromal tumor. Due to this tumor?s rarity in childhood, the paraffin-embedded tissue samples were referred for a second opinion. Histological and immunohistochemical characteristics of the tumor made the gastrointestinal stromal tumor diagnosis unlikely and consistent with a completely resected gastric schwannoma. No recurrence of the disease occurred during the seven-year follow-up. Conclusion. Combined laparoscopic-endoscopic surgery is a feasible and effective treatment for large gastric tumors that cannot be excised endoscopically. Schwannoma should be included in the differential diagnostic consideration of gastric tumor lesions even in childhood.
