Percutaneous transhepatic biliary drainage (PTBD) catheter site metastasis in cases of cholangiocarcinoma is reported sporadically. But it is unusual to see left-sided tumour metastasising to the right PTBD catheter site. Metastasis, in general, has a poor prognosis, but recurrence along the catheter tract in the absence of other systemic diseases can be a different scenario altogether. To date, there is no consensus on the management of this form of metastasis. But carefully selected patients can benefit from aggressive surgical resection. We report a case of a young patient with isolated chest wall metastasis 1 year after resection of left-sided hilar cholangiocarcinoma. The metastasis was resected and, on pathological analysis, was confirmed to be due to implantation of malignant cells along the tract of the PTBD catheter placed via a transpleural route.
