Abstract
Summary 1. Three types of Mantoux reaction pattern based on estimates of diameter and depth of induration are described. 2. A specific modification of the normal patterns, characterised by extreme transience of induration, was seen in 51·8 per cent. of the cases of active pulmonary tuberculosis and 31·8 per cent. of the cases of primary pleural effusion examined. This change has not so far been encountered in any patient not suffering from active tuberculosis. The possible significance and mechanism of this change are discussed.
