ABSTRACT
The pre-operative differential diagnosis of gastric subepithelial lesions is complex. We can find pathologies with a very different behavior. Some of them, like gastrointestinal (GI) stromal tumors, can present a malignant behavior, and others like schwannomas are practically benign. Schwannomas of the GI tract originate from the Schwann cells of the Auerbach plexus and their most frequent location is the stomach. The definitive diagnosis is made by immunohistochemical analysis of the surgical specimen and its resection is curative. We report two cases of gastric subepithelial lesions with a definitive diagnosis of schwannoma.

El diagnóstico definitivo se realiza mediante el análisis inmunohistoquímico de la pieza quirúrgica, y su resección es curativa. Reportamos dos casos de lesiones subepiteliales gástricas con diagnóstico definitivo de schwannoma.

Gastrocutaneous fistulas (GCF) following removal of gastrostomy tubes are an uncommon complication with many therapeutic options. It is a drawback that concerns both patient and surgeon, hindering the decision to perform an invasive treatment. Despite emerging minimally invasive procedures, we must not forget that surgery continues to be the standard treatment when they all fail.
