Abstract
Epithelioid sarcoma (ES), a mesenchymatous malign neoformation, is often diagnosed in later stages and associated with high recurrence index, metastasis and mortality. We report a case of a 65 years old male, with history of abdominal pain and upper gastrointestinal bleeding. Endoscopy demonstrated a posterior duodenal wall perforation communicating with a solid retroperitoneal neoformation. Endoscopic biopsy was performed, with a final report of ES. The patient was submitted for surgical palliation due to the tumor’s unresectability. Retroperitoneal ES is an extremely rare condition with limited reports in the literature where guidelines for its optimal treatment are not well established.
Core tip: Epithelioid sarcoma (ES) is a rare malign neoformation, often diagnosed in later stages and associated with high recurrence index and mortality. We report a case of a 65 years old male with a posterior duodenal wall perforation found during endoscopy, communicating with a solid retroperitoneal neoformation. Endoscopic biopsies were sufficient for the diagnosis. Retroperitoneal ES is an extremely rare condition with limited reports, where guidelines for its optimal treatment are not well established.
