Bean with increasing years so that in the thirties about three- (juarters of the ])ersons observed have the lesions and they are almost always found in the aged. Not only do more people become affected but the spots are more numerous and larger. Caviar Lesions The caviar lesion is a small, roughly spherical or dome- shaped varicose enlargement of the poorly supported veins 10- 19 20-29. 80 100 Fig. .'5. Incidence of caviar tongue lesions l)y sex and decade. in the collecting system under the tongue. The small ones develop as an outpouching of a branch of a communicating vein near the ranine veins. Pressure with a glass slide causes them to empty. Knots and clusters of such vessels with a dark blue or black colour resemble caviar or buck shot (see Fig. 4). Anatomically the caviar lesion is a dilated vein with hypoplastic endothelium but a fairly thick wall. There are no inflammatory changes. Age: There is a sharp and fairly steady increase in incident with increasing age; and the lesions grow larger and more numerous (Fig. 5)..
