Combined laparoscopic-endoscopic “rendez-vous” procedure in a case of gastric schwannoma in a toddler

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