Primary colon adenocarcinoma with metastatic disease to the rectum followed by the left axilla

Am Med Stud Res J. 2017;4(1):57-61. doi: 10.15422/amsrj.2017.03.009.


Introduction: Adenocarcinoma of the colon can metastasize to multiple organs but very rarely metastasizes to the axilla.

Case: We present a case of a 56-year-old male with metastatic colon adenocarcinoma that metastasized to the rectum and then the axilla. Three years after initial diagnosis and treatment of right colon mucinous adenocarcinoma a metastatic mass was found in the rectum. The mass was successfully resected, but within a year of finding the rectal mass, metastatic disease to the axilla was discovered.

Conclusion: This case provides valuable teaching points about routes of metastasis and the importance of continued clinical follow-up in patients diagnosed with adenocarcinoma of the colon.
