Colonic Carcinoma Invading the Kidney: Case Reports

Renal metastasis from primary colon cancer is so rare that, from USA, Nelson’s associates reported “a unique case of a 51-year-old female with extra luminal colonic adenocarcinoma which directly invaded into the kidney.” Therefore, the author describes two such cases among 50-year-old females who belong to the Igbo ethnic group [1,2]. This was facilitated by the advice of a Birmingham (UK) group [3]. As they had put it, the establishment of a histopathology data pool is fruitful epidemiologically. Concerning the present cases, being the pioneer pathologist at the Regional Pathology Laboratory established at Enugu by the Government, I was in the position to observe such obscure relationships in cancer metastasis [4].
