FREQUENCY OF HEALED TUBERCULOSIS OF THE MESENTERIC GLANDS

Warthin¹ has carefully examined a large number of lymph nodes, primarily in order to determine the anatomic type of the given gland, and one noteworthy demonstration is the constant occurrence in the mesenteric and retroperitoneal lymph nodes of adults of small hyalin masses. These hyalin masses stain red with acid dyes (eosin and fuchsin) and occur in any part of the node, more frequently, however, in the cortex; they are usually round with sharp borders, varying in size from minute microscopic points to small masses visible to the naked eye. In the larger masses a few nuclei are present; the smaller may be wholly devoid of nuclei, suggesting their being older, while the larger show various stages of a hyalin change in the connective tissue replacing some lesion. These hyalin masses are hyalin scars. In the center of larger masses small deposits of lime salts often occur and reactions
