Gastric schwannoma with atypical manifestations in an adult patient: case report and literature review

TL;DR

A rare case of gastric schwannoma in an adult is reported, highlighting its diagnostic challenges and successful surgical treatment.

Contribution

This case report adds to the limited literature on gastric schwannomas with atypical clinical manifestations.

Findings

A 61-year-old female presented with gastric fullness and abdominal pain due to a gastric schwannoma.

Immunohistochemistry confirmed the diagnosis after initial suspicion of a gastrointestinal stromal tumor.

Surgical resection was effective in treating the gastric schwannoma.

Abstract

Gastric schwannomas (GS) are rare tumours originating from Schwann cells that affect the gastrointestinal tract, posing a diagnostic challenge due to their nonspecific symptoms. We report the case of a 61-year-old female presented with gastric fullness and occasional episodes of abdominal pain. Computed tomography revealed a solid mass in the lesser curvature of the stomach, initially suspected to be a gastrointestinal stromal tumours. During surgery, an exophytic lesion was identified and confirmed histopathologically and immunohistochemically as a gastric schwannoma. GS should be considered in the differential diagnosis of gastric subepithelial tumours. Its diagnosis relies on immunohistochemistry, and surgical resection ensures effective treatment.
