The Isopathic Phenomenon in Infiltrated Tuberculoid and Macular Tuberculoid leprosy

چکیده
In a number of papers since 1952 Sagher and associa tes (18. 27. 29-35 ) have called attention to a specific tissue response of the noninvolved skin of lepromatous leprosy on intradermal injection with various agents. Tuberculin , leishmanin , milk, p eptone and living leishmanial leptomonads elicited a prelepromatous or lepromatous infiltration, usually without bacilli, at the site of the injection. This capacity of the skin to react to various agents with a histologic pattern characteristic of the host's tissue response was called an "isopathic phenomenon." (35 )

متن کامل"Tap sign" in tuberculoid and borderline tuberculoid leprosy.
Deep pain upon percussion of lesions over bone in tuberculoid leprosy, in spite of superficial sensory impairment, has been described as the "Tap Sign" (TS). This study was conducted to identify possible causes for this phenomenon and to determine the sensitivity and specificity of this sign in leprosy patients with lesions overlying bone.

متن کاملClassification of leprosy.
The three latest International Congresses of leprologists (Madrid 1953, Tokio 1958, Rio 1963) have recognised two polar types of leprosy, tuberculoid and lepromatous and one inter mediate group, borderline. These three categories faintly reflect the con cept of a spectrum of clinicai, immunological, bacteriological and histological signs. Apart from these categories a group of cases with inch...
