Manifestations of lepra reaction in cases of tuberculoid leprosy

Manifestations of lepra reaction in cases of tuberculoid leprosy or in individual tuberculoid lesions have not been described as such. Evidence of its occurrence would doubtless be found in the literature if it were searched interpretivelybearing in mind the fact that tuberculoid lesions are usually not recognized for what they are. For example, the peculiar nerve abscess common in India is probably a reaction condition, as Lowe believes (1), and as is shown in another paper (2) a specimen of the condition obtained through his courtesy has proved to be tuberculoid. In South Africa a reaction condition is recognized clinically among cases of the sort that \ye have shown to be tuberculoid (3, 4) . The writer was privileged to see several of these reaction cases, and certain others that are suspected of having been in a reaction state of less degree. The material studied is sufficiently peculiar to be discussed separately, this report supplementing that dealing with the ordinary phases of tuberculoid leprosy as seen in South Mriea.
