Abstract: The association between hepatic tumours and oestrogen and progestogen therapy is well established. The risk of developing primary hepatocellular carcinoma (PHC) is small. In Africa and Asia where hepatitis B virus (HBV) infections are common, the development of PHC is also high. The presence of Hepatitis B core antibody indicates previous exposure to HBV and carries a risk of developing PHC by more than 34 times of noninfected normal. A Chinese female age 29 years who had been on oral oestrogen and progestogen contraceptives continuously for 8 years developed PHC. She had no known illness due to HBV but was found to have concomitantly positive Hepatitis B core antibody in her sera. The presence of this HB core antibody and the long term consumption of oestrogen/progesterone derivatives may have been responsible for the early presentation of PHC in this patient. It is the first report in this country of PHC developing in a pill consumer since the introduction of oral contraceptives a decade ago. In view of the prevalence of Hepatitis B in the region, this case finding warrants further study to determine whether there is a higher frequency in pill consumers, an earlier age of presentation of hepatic malignancy. Meanwhile, it may be prudent to recommend alternative methods of birth control in individuals known to have been previously exposed to HBV infection, clinically or otherwise.
