Аннотация
INTRODUCTION: Gastroblastoma is a rare gastric biphasic tumor with both epithelial and mesenchymal components. To the best of our knowledge only eight cases have been reported in the English literature till date.
PRESENTATION OF CASE: We report a case of a 29-year-old female, hospitalized for epigastric pain with poor general condition. An upper gastrointestinal endoscopy showed a polypoid mass in the stomach near the gastric cardia suspicious of gastrointestinal stromal tumor. The patient underwent atypical proximal gastrectomy with splenectomy. Detailed histopathological examination of the resected specimen revealed the diagnosis of gastroblastoma. After six months, the patient developed loco-regional recurrence for which surgical debulking was performed.
DISCUSSION: Gastroblastoma is predominantly seen in young adults with non-specific complaints. They appear as submucosal lesion in the stomach mimicking gastrointestinal stromal tumor. Preoperative diagnosis is often difficult. Surgical resection remains the mainstay of treatment. On histology, they consist of mesenchymal component which stain positively for vimentin and CD10 and epithelial component which is positive for cytokeratin on immunohistochemistry.
CONCLUSION: Gastroblastoma is a malignant tumor with risk of local recurrence after curative resection.
