Case Report - Colonic Adenocarcinoma Presenting as a Cutaneous Metastasis in an Old Operative Scar

Cutaneous metastasis from colon cancer is an uncommon event that usually occurs after identification of the primary tumour and generally indicates diffuse disease. Incisional metastasis occasionally occurs following laparoscopic or open colon cancer resection. However, to the authors' knowledge only one previous case of colon cancer presenting as a cutaneous metastasis in an old operative scar has been reported. We describe a case of colon cancer presenting as a cutaneous metastasis in an old cholecystectomy scar and discuss possible pathophysiological mechanisms. (J Postgrad Med 2003;49:157-158)
