Tuberculide - A Clinical and Epidemiological Review

KT Chan

Abstract
Tuberculide is a rare cutaneous disorder but its recognition is important as it is a readily treatable disease. True tuberculide mainly consists of three main types, namely, papulonecrotic tuberculide, lichen scrofulosorum and erythema induratum of Bazin. While there is still much controversy about its relationship with tuberculosis, application of DNA technique has provided us with a more definite answer. In the following article, we first update the diagnostic criteria and classification of tuberculide. This is followed by a comprehensive review on the epidemiology of the tuberculides. Important clinical features of the tuberculides will be highlighted in the article. Finally, the modern development of polymerase chain reaction with its application in the study of tuberculide will be discussed.
