The tumor seeding after percutaneous ethanol injection (PEI) therapy has been considered to be a rare complication in hepatocellular carcinoma. We report a case of needle tract implantation of hepatocellular carcinoma following PEI manifested as subcutaneous nodule. A 57-years old male patient had been treated with PEI for hepatocellular carcinoma. Thirteen months after completion of the PEI session, a subcutaneous nodule was palpated at the site of the needle puncture. A CT scan showed that the subcutaneous nodule was 1.7 cm in size and enhanced in the early phase. The nodule was surgically removed. Microscopic examination showed hepatocellular carcinoma.

METHODS: We performed a retrospective study of 2380 elderly patients who visited Emergency room of national medical center, from August 1, 1999 to July 31, 2000. We analyzed the patients gender, age, arrival time, final diagnosis, admission rate, mortality, ects. RESULT: Male to female ratio is 1:1.29, and most common age group was between 65 and 69 years old. The peak time of patients entrance was between 10 AM and 11AM, in a week monday was most crowding day. The most predomint monthly distribution of visit was January. The respiratory disease are most common problem (14.7%), and cardivascular disease (12.01%) are next, and cerebrovascular disease (11.17%) are following. Diabetic complication (7.53%) are common problems and hypoglycemia and diabetic foot infection are frequent. Admission rates was 32.53%. ICU admission rate is 2.77%. Emergency operation rate is 5.91%. During admission, mortality case was 127 patients. The cause of death were cerebrovascular disease (16.94%) and advanced respiratory disease (15.43%). CONCLUSION: The results show that cerebrovascular disease and respiratory disease and cardiovascular disease that needed prompt medical service are major problem who visit emergency room. And diabetic complications that are prevented by proper educations are common. So more concentrated medical service and preventive effort focused on these disease.
