Abstract
Spontaneous remissions have been reported in solid tumors such as melanoma and renal cell cancer. However, spontaneous remissions in colon cancer have not been previously radiographically confirmed. A case of colon cancer metastatic to the retroperitoneal lymph nodes that exhibited a durable spontaneous regression is reported. The exact trigger of this phenomenon has not been elucidated; however, an antitumor immune response is the most likely explanation. The identification and characterization of similar cases would probably result in defining a patient population that can be followed by observation and may result in the development of novel therapeutic strategies.
