Abstract

  This report presents a case of solitary inguinal metastasis after treatment of rectal cancer by abdominoperineal resection. A 79-year-old Omani man was diagnosed with poorly differentiated mucinous adenocarcinoma of the rectum in March 2015. Metastatic involvement of inguinal lymph nodes (ILN) from rectal adenocarcinoma is unusual presentation, particularly without signs of distant spread to other organ sites. In the current time, ILN involvement, including solitary involvement, is classified as metastatic disease (M). Inguinal mass was totally excised; neoadjuvant radiation therapy and chemotherapy had been also carried out before. Pathological analysis showed poorly differentiated mucinous adenocarcinoma compatible with his rectal cancer. The interesting finding was that this case did not seem to belong to any traditional rectal cancer metastasis pathway. This case is representative and worthy of further study to explore whether there is another rectal cancer metastasis pathway.
