title: [Pathological findings of the liver in Hansen's disease].
abstract: In leprosy patients, granulomatous lesion are often observed, not only in skin and nerve, but also other visceral organs such as liver, kidney, spleen and cardiovascular system. But for the development of drug therapy, there are very few cases we can see the acid-fast bacilli in the lesion these days. We have reviewed the histopathological lesions in the liver of leprosy patients who had been treated for long term, based on autopsy findings of 31 cases, including 24 cases with lepromatous leprosy (LL) and 7 cases with tuberculoid leprosy (TL). Except one case of LL with progressive stage, most of them diagnosed as retrogressive or quiescent stage. Morphologically, acid-fast bacilli and granuloma were seen in a few cases of Hansen's disease. In addition, no suggestive changes of drug and virus induced liver injury were recognized. However, sclerotic change of portal vein was remarkably encountered in the tuberculoid leprosy.
