reported. We describe two such cases following the needle biopsy of an hepatocellular carcinoma and
secondary colorectal carcinoma respectively. The risk of needle track recurrence of liver tumours should
not be regarded as insignificant. The diagnosis of liver neoplasms may be achieved by non-invasive
modalities, and their needle biopsy should be reserved for cases not amenable to surgical resection.</p>
