Imprint cytological diagnosis of colonic adenocarcinoma metastatic to liver.

The liver is a common visceral site for metastatic tumours. Radiological features of the liver, fine needle aspiration cytology (FNAC) and histopathological evaluation (HPE) of liver nodules have a significant role in pre-operative diagnosis of liver lesions. In an intraoperative setting, frozen section biopsy plays a major diagnostic modality but the role of imprint cytology of liver nodules is also appealing. Imprint cytology is a valuable and precise tool in diagnosing the lesions for a rapid intraoperative diagnosis. This study presents a case of colorectal cancer liver metastasis diagnosed by imprint cytology intraoperatively.
