MICROPAPULAR TUBERCULID AND ROSACEA

Abstract

THIS study was prompted by the belief that resistant rosacea in many cases has been diagnosed cutaneous tuberculosis because of the term rosacea-like tuberculid. Lewandowsky's 1 classic description, which was reintroduced by MacKee and Sulzberger 2 and Wile and Grauer, 3 will not be repeated in detail here. The eruption occurs on the face and consists of purplish or brownish red papules or papulopustules. There may be distinct hyperemia and telangiectasia of varying amount. Under diascopic pressure a small amount of yellowish brown staining remains. We believe that many cases in which the diagnosis was rosacea-like may after careful analysis prove to be rosacea and not tuberculosis or, in other instances, the disease may be some other type of tuberculosis, such as lupus miliaris disseminatus faciei, papulonecrotic tuberculid or even papular sarcoid. In many cases the diagnosis of rosacea-like has been made without strict adherence to the criteria
