Follicles distinctly outlined,
slightly large but merely of a slightly paler purple than pulp. On
surface are many round 2–5 mm. sharply outlined gray thickenings of
the capsule and immediately subjacent pulp. The right kidney’s lower
half has been replaced by a thin-walled clear cyst 3 × 2.5 × 2 cm. The
left kidney is small, capsule strips with difficulty tearing surface
slightly. Surface and section are mottled pink and gray, glistening
and opaque. It is firm, dense and tough, cortex narrow, medulla wide.
Cortex has obscure, irregular markings with few small cysts, striæ and
glomeruli, faintly visible, margin between layers irregular. Veins are
distended over surfaces of stomach, under surface of diaphragm, in
peritoneum over liver but not in abdominal wall. Stomach contains sour
gas and water. Mucosa especially near cardia is deep purple. Rugæ are
large and permanent but mucosa and submucosa are soft and on section
congestion does not extend deep. The tips of the rugæ near pylorus are
infiltrated and the infiltration is surrounded by a zone of
congestion. Mucosa seems about to slough but has not separated. At
pylorus mucosa becomes deep brown-red, dense, swollen, opaque and
covered with a slimy, soft brown mucus. Folds are prominent but
temporary. In jejunum and ileum mucosa is still swollen and opaque and
rugæ are still larger than normal and temporary with a dense sensation
on compressing them. The color is not brown but deep pink and yellow
with areas of submucous injection. Follicles not visible. Colon is
negative except for slight thickening of mucosa unaccompanied by
congestion or opacity. Lymph glands of small omentum are small, firm,
yellow, homogeneous; those of the mesentery are large, edematous,
yellow brown and tense with lymph which escapes on section. Lymph
channels up to mesenteric stalk can be traced.
