We analyzed the severity grades of the skin symptoms of Yusho patients who visited the annual examinations in 1999 and 2000. The severity grades of the skin symptoms clearly improved. The patients graded as 0 increased and those graded as II.III-III or III.IV-IV decreased as compared to the data in 1993. The pattern of the skin severity scores did not change much, although the patients who showed 0.1 reached 68% in 2000. The blood PCB concentration of Yusho patients also clearly decreased, especially in the patients who showed "A" pattern. Furthermore, the skin changes of the aged patients should be analyzed in detail in the future.
