Abstract

Pathological differentiation is important for suspected lesions of metastatic undifferentiated pleomorphic sarcoma (UPS) because no reliable imaging criteria exist for this entity yet. In the present case, transgastric endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for the pancreatic tumor and transcolonic EUS-FNA for the intraabdominal tumor contributed to the definitive diagnosis of metastatic UPS, leading to appropriate treatment selection.

Keywords: extracolonic lesion; pancreatic metastasis; transcolonic endoscopic ultrasound‐guided fine‐needle aspiration; undifferentiated pleomorphic sarcoma.
