Kidney.—Capsule smooth, interstitial fibrous tissue of organ proper highly fibrosed in peripheral parts, but slightly in deeper. No lymphocytic infiltrations anywhere or sclerosis of vessels. Tubular epithelium highly atrophic in subcapsular regions where tubules are narrow. In deeper parts epithelium is at times so swollen as to occlude lumina, where they are coarsely granular and occasionally show some karyolysis, a pink hyaline or finely granular material. Tufts never show fibrosis, normal size. Bowman’s capsule heavily thickened. Chronic diffuse nephritis (subcapsular type). Spleen.—Slightly hyalinized capsule, normal thickness. General reticulum of pulp slightly fibrosed and poor in lymphocytes. Sinuses broad, crowded with red blood cells, but only small numbers of lymphocytes. Coarse granular blood pigment abundant, showing greenish cast on focusing. Malpighian follicles normal size, slightly fibrosed, and in several instances show a deposit of smooth pink material between cells. Congestion. Fibrillar fibrosis. Hemosiderin pigmentation. Local amyloid infiltration. Adrenal.—Organ appears normal in all respects save for presence of a few small irregular areas of calcification in medulla. These occur apart from any recognizable necrotic or fibrous areas. In one place one appears to lie within lumen of blood vessel. No fibroses or special congestions anywhere in organ, and cells show normal details and normal numbers of vacuoles. Calcareous infiltration of medulla. Stomach.—Muscular tunic normal. Submucosa thin, has densely arranged bundles of smooth, pink character. Mucosa distinctly thinned, shows comparatively few regions holding acid cells, consisting for most part of peptic type of gland. These are short and of broader calibre towards lumen than deeper, suggesting a hyperplasia of luminal portions; stroma richly infiltrated with lymphocytes, not fibrosed or congested. Epithelium of crypts has rarefied appearance, shows no special degenerative changes. Chronic atrophic gastritis. Bone marrow appears as widely separated large, fat globules with intervening granular edematous material and no hematopoietic elements. Blood capillaries numerous and highly congested.
