Acute pancreatitis due to osteosarcoma metastasis.

We present the case of a young patient with acute pancreatitis (AP) secondary to osteosarcoma metastasis. It is necessary to assess tumor etiology in the study of any acute pancreatitis without clear cause. Pancreatic metastases are rare and difficult to diagnose and differentiate from other primary tumors such as neuroendocrine tumors (NET). It is essential to have a high degree of clinical suspicion and the use of radiological and endoscopic ultrasound imaging techniques.
