Recurrence of gastric schwannoma.

Gastric schwannoma can be malignant in 13.8% of cases. The prognosis of malignant schwannoma is usually poor, characterized by a rapidly progressive disease course and a poor response to chemotherapy. Normally, the recurrence of schwannoma is due to involvement of the surgical resection margin. In turn, recurrence of malignant gastric schwannoma GS is approximately 50%, 25% locoregional and 25% with liver metastases. Even after a complete gastric resection with associated lymphadenectomy, schwannoma may present liver metastases during follow-up.
