Acellular mucinous lymph nodes in colonic mucinous Adenocarcinoma

This is an interesting case report on a 72 year old female who underwent an elective right hemicolectomy for a mucinous tumour. Histology revealed 15 lymph nodes with two entirely replaced by mucin without evidence of metastatic tumour cells. The rest of the lymph nodes were normal. After discussion at the local colorectal multidisciplinary meeting these were treated as lymph node metastases and the patient received adjuvant chemotherapy. There is little evidence around the management of colonic carcinoma with acellular mucin evident in lymph nodes
