[Endocarditis parietalis fibroblastica (Löffler) combined with osteomyelofibrosis (author's transl)].

An autopsy case with coincidence of endocarditis parietalis fibroplastica (Löffler) and osteomyelefibrosis is described. The osteomyelofibrosis in this case is considered as a complication of Löffler's endocarditis and therefore as a secondary event. The case demonstrates a possible development of the osteomyelofibrosis by allergo-toxic damage of bone marrow or in consequence of arteriitic circulation disturbances. Our findings speak against the exclusively tumourous or leucotic nature of this process.
