Fibronectin is a multifunctional large molecular weight glycoprotein that can bind extra-cellular and cellular components. The aim of the present study was to evaluate expression of fibronectin and its significance in cases of hepatocellular carcinoma (HCC). A few previous studies have shown abnormal over- expression of fibronectin in cases of HCC. Expression of the fibronectin protein was studied in eleven cases of HCC by immunohistochemical method. Fibronectin was seen to localize predominantly in perisinusoidal region and strong positivity was noted in other fibrotic areas. Positivity around nests of cells and tumor nodules was noted in 8/11 cases of HCC and faint cytoplasmic positivity in tumor cells was seen in 5/11 cases. Staining pattern of fibronectin in HCC was definitely abnormal but decreased in the present study. The controversial results as seen in few previous studies also have been partially explained in the present article and further studies using larger sample size is suggested to clarify the issue.
