SPLENIC HYPERTROPHY IN THE DOG.
This condition has been less frequently seen in dogs, the recognizable causes having been traumatism (Notz), and leucocythæmia (Zahn, Forestier, La Forgue, Nocard). Lymphadenoma is another complication (Nocard, Leblanc, Siedamgrotzky, Bruckmüller). The spleen has been found to weigh 2 lbs., (Bollinger, Siedamgrotzky). As in other animals the enlargement of the Paccinian bodies has been a marked feature. In other cases the splenic lymph glands are enlarged.
The symptoms are obscure as in other animals. Yet the presence of white cell blood, with a predominance of eosinophile cells, enlargement of the abdomen, and the detection of a large solid body in the left hypochondrium which proves tender to the touch may prove more satisfactory than in other animals. In certain cases it has obstructed the biliary duct by pressure and entailed hepatic disorder and jaundice.
The treatment would not differ from that of the larger animals.
Siedamgrotzky has also observed splenic hypertrophy in the cat in connection with leucocythæmia.
