A histopathological study of lymphnodes in 43 cases of leprosy.

ABSTRACT

Eighty cases of leprosy including 60 cases of lepromatous type and 20 cases of tuberculoid type, during the period of 1974-75, have been examined for evidence of lymphnode enlargement. Of the 52 cases of enlarged lymphnodes, lymphnode biopsy was done in 43 cases including 38 cases of lepromatous type and 5 cases of tuberculoid type. The lymphnodes have been studied for evidence of any pathological changes and presence of acid-fast bacilli. In cases of lepromatous leprosy, lepromas and acid-fast facilli were seen in 92.2 per cent of the cases and patchy fibrosis was noted in 23.6 per cent of the cases. No amyloid could be demonstrated. In cases of tuberculoid leprosy, only non-specific reticular hyperplasia was noted. No specific granuloma or acid-fast bacilli could be demonstrated. The findings have been described in detail and discussed in the light of previous published data.
