lesions can be classified by clinical and bacteriological examinations without difficulties so that during a general survey biopsies may be exempted in such cases. Notwithstanding;pathological examinations should not be omitted in reactional cases;astlansformation into iepromatous type waspossible.b. In cases with lesions formerly classified as macule-anaesthetic;special references on histological and immunological examinations was deemed necessary. Histologically;those with tuberculoid infiltrations were classified as macular tuberculoid;while those showing mononuclear infiltrations only were classified as indeterminate. Immunologically;cases showing a negative lepromin reaction were considered lepromatous;whereas those with a positive reaction were considered either as tubcrculoid or indeterminate type.c. Boderline cases have not been observed in our series. As this group is rather uncommon the authors are of the opinion that for simplicity’s sake it may be included in thereactive phases of tuberculoid or lepromatous leprosy..In China;as suggested in this paper;to classify leprosy into 3 types’ Lepromatous;Taberculoid and Indeterminate is practicable and satisfactory.The results of classication in this series of 71 caes were lepromatous 17;tuberculoid 39 and indeterminate 15 .9 .The following cases with special clinical interest were reported and discassed:a. A pecular phenomenon;Iiquefacative necrosis in nodular lesions developed in 3 cases of advanced Iepromatous leprosy. The clinical and histological picture was quite different from Lucio’s erythema and other forms of leprous reaction.b. A rare complication;diabetic coma was seen in one case of advanced leproma tous leprosy during DDS treatment. The coma was soon relieved after insulin therapy;and tater on kept in check by dietetic control alone;no recurrence of symptoms of diabetes mellitus took place after follow-up for 1 year.c.
