21,6  Mendoza-Guazon: Schistosomiasis in the Philippines 547 
Mesenteric lymph nodes.—Groups of ova are found in the border line of 
the cortex and medulla, encapsulated by fibrous tissue with few eosinophiles. 
Isolated ova are also found outside the capsule without any sign of reac- 
tion around them. Another group of ova is also present in the medulla 
with giant cells and without any capsule. The sinuses are dilated and filled 
with lymphocytes and eosinophiles. Other sections of mesenteric lymph 
nodes are completely packed with eggs, especially the medullary portion. 
Many of the follicles are intact, but others contain ova; even the capsule 
is not free from them. 
Peribronchial lymph nodes.—Eosinophilie infiltration. 
Heart.—Eosinophilic infiltration in the septa, and congestion. 
Spleen.—Congestion and fibrosis. 
Kidney, testes, pancreas, and prostate are free from ova and do not 
have eosinophilic infiltration. Sections stained by Willyoung’s method (35) 
show brilliant red ova and clear blue tissue. 
ANATOMIC DIAGNOSIS 
Acute dilatation and hypertrophy of right heart; acute dilatation of 
left heart; chronic myocarditis; hydropericardium; chronic endocarditis; 
congestion of lungs with slight hemorrhages; chronic obliterative pleurisy, 
left; hydrothorax, right; necrotic nodules, two, left; chronic passive con- 
gestion of spleen; chronic perihepatitis; chronic passive congestion of kid- 
neys; chronic perisplenitis; cirrhosis of the liver; mucous tumors of sig- 
moid; tumor in appendix; ascites; acute lymphadenitis, retroperitoneal, 
mesenteric, and celiac axis; oedema of mediastinum; congestion of me- 
ninges and brain substance; uncinariasis trichocephaliasis; ascariasis; 
schistosomiasis. 
In this case we have an adult worm in the portal vein of the 
liver, ova in the liver, mesenteric lymph nodes, and colon, with 
eosinophilic infiltration in these organs and in the peribronchial 
lymph nodes and heart. There is absence of ova and eosino- 
philia in the kidneys, testes, prostate, pancreas, and spleen. 
The gross pathological anatomy is that of a terminal case of 
infection with Schistosoma japonicum. 
SECOND CASE 
F. V., Filipino male, 18 years old, residing in Tondo, Manila, died of 
electrocution on June 12, 1914. 
Morbid anatomy.—Autopsy 3241. Body is that of an adult, male Fili- 
pino, 150 centimeters in length and weighing 43.49 kilograms. On the 
anterior aspect of the thorax there is a large gaping wound, which extends 
completely across the thorax and through its entire depth as far poste- 
riorly as the vertebral column, completely severing all structures. The 
pleure are firmly adherent to the thoracic wall and diaphragm. 
Intestines.—Some of the epiploic appendices are firm and pale. In the 
ileum there is marked prominence of the lymphoid tissue, which is pale. 
In the cecum and extending throughout the entire colon there are numerous 
groups of nodules, which are small, discrete, conglomerate, elevated, coni- 
cal, with for the most part umbilicated centers. These form irregular
