The present study deals with pathoanatomic and pathohistological changes of spontaneous vitamin E and selenium deficiency in growing piglets.
The studies took place in 1990–1997 on the territory of Plovdiv area, the material involved 84 carcasses of dead pigs and 27 carcasses of pigs slaughtered by necessity.
The pathoanatomic investigations revealed hydropericardium, hydrothorax, ascites, liver dystrophy, hemorrhages and white striations in the epicardium and endocardium, edema of lungs, subcutaneous and mesenterial adipose tissue, ruptures in diaphragm muscles, lesions in the cardial area of stomach mucosa as well as generalized icterus of various degree.
The pathohistological changes are expressed in: dystrophy and necrosis of liver parenchyma, parenchymal and hyaline dystrophy in the heart, diaphragm and skeletal muscles, lungs edema, parenchymal dystrophy and hemorrhages in the renal cortex, perivascular and pericellular brain edema.

Key words: vitamin E and selenium deficiency, hyaline dystrophy and parenchymal dystrophy
