Metachronous prostate and colon adenocarcinomas.

Multiple primaries in patients with prostate cancer are uncommon. We report a case of prostate adenocarcinoma who did not receive any form of treatment, diagnosed 7 months later with colon adenocarcinoma. The patient underwent right extended hemicolectomy and recovered well. He is planned to receive adjuvant chemotherapy and hormonal therapy. Management of such cases can present a dilemma and multiple factors must be taken into consideration, particularly when the first primary tumour is still active.
