Primary Colon Adenocarcinoma with Metastatic Disease to the Rectum Followed by the Left Axilla

Abstract

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.

Paratesticular metastasis arising from colonic mucinous adenocarcinoma: a rare case report

“…The occurrence is rare, but liberal use of positron emission tomography/CT scans and the semi-dry dot-blot technique is encouraged to diagnose metastasis early. 5 Other sites of metastatic spread include the liver (35%–50%), lungs (21%), and bone (8.7%). 4 , 6 Metastasis of colon cancer to the scrotum is extremely rare; we have herein described such a case.…”

Case report: A balance of survival and quality of life in long-term survival case of lung adenocarcinoma with synchronous bone metastasis

“…To identify targeted therapy or immunotherapy potentially benefiting survival, molecular testing should be performed and individual treatment should be planned according to the resting results ( 12 ). Notably, systemic imaging examination was emphasized for advanced cancer patients to detect unusual metastatic sites ( 24 ). Solitary suspicious lesions, especially those in uncommon locations such as the skull, should be carefully diagnosed to exclude metabolic and other diseases ( 25 ).…”

Axillary Lymph Node Metastasis as the First Symptom of Colon Cancer

“…It seems that intercommunicating lymph flow and reflux of lymph from the para-aortic node into the thoracic duct are the likely route of cancer spread to the axilla. 9,10 This case suggests that we should be aware that the first symptom of axillary lymph node enlargement has the possibility of colon cancer metastasis. FDG PET/CT is quite useful for finding out the primary tumor site.…”

“…In our case, there was no abdominal wall invasion, and no hematogenous metastases were detected. It seems that intercommunicating lymph flow and reflux of lymph from the para-aortic node into the thoracic duct are the likely route of cancer spread to the axilla 9,10 . This case suggests that we should be aware that the first symptom of axillary lymph node enlargement has the possibility of colon cancer metastasis.…”
