Abstract
|
|
|
|
A-49-year-old male patient with no specific medical history was admitted to the clinic because of persistent epigastric pain radiating to back for 4 months. He had multiple parenchymal tumors in body and tail of pancreas, para-spinal muscle, and mediastinum on abdomen CT image. Cytologic examination of the pancreas which was done by endoscopic ultrasound guided fine needle aspiration (EUS-FNA) showed adenocarcinoma, whereas histological examination of the para-spinal mass showed undifferentiated sarcoma. Histologic examination of the pancreatic mass was made through endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for accurate diagnosis, and the histologic examination of both the pancreas and posterior mediastinal mass showed the same undifferentiated sarcoma. Therefore, we reviewed the cytopathic tissue obtained from the pancreas for the first time, and it was confirmed to be similar to histologic findings in the mediastinal mass.
