Reveal Findings

Non-contrast CT of the chest suggests a noncalcified mass in the tail of the pancreas which is confirmed on post-contrast dedicated pancreatic CT. The gross pathological specimen correlates nicely with the CT imaging. Histology
demonstrated pleomorphic nuclei embedded in chondroid and osteoid matrix.

Reveal Discussion

Micrometastatic disease is usually present at the initial diagnosis of osteosarcoma. Metastatic disease in osteosarcoma is most often seen in lung (98.1%), skeleton (37.0%), pleura (33.3%), heart (20.4%), kidney and liver (16.7%), diaphragm (14.8%), mediastinum (11.1%), and lymph node (7.4%) by autopsy. There have been case reports of metastasis to the skin, dura, brain, peritoneum, muscle, bowel and bronchi; only 3 previous cases of metastasis to the pancreas reported. Unusual metastatic sites are common in patients with multiple recurrences.
