Triple Primary Origin Tumor: A Case Report

Abstract

Generally, among the extradural spinal tumors, metastatic spinal tumor is much more common than primary spinal tumors. Thus, in the case of a spinal tumor patient with cancer history (such as lung cancer, breast cancer, etc.), we used to infer that the spinal lesion is the metastasis from, primary malignancy. We introduce an experience of a case of triple primary origin tumor in a 57-year-old man. When the spinal lesion was found on the abdominal computed tomography scan, he already had a history of colon cancer and liver cancer. Initially, it was thought that the lesion would probably be a metastatic tumor from the liver or colon cancers, and the operation was performed accordingly. In the pathologic final report, however, the mass was proven to plasmacytoma - the third primary lesion. The patient underwent chemotherapy after surgery. Globally, the triple primary origin tumor has been reported very rarely. With this report, we wish to emphasize the necessity of pathologic confirmation and adequate treatment even in a patient with known malignancies.
