[Giant cell myocarditis. Attempt at interpretation, apropos of 3 cases].

Three cases of giant-cell myocarditis were observed, and 63 comparable cases were published in the literature. On the basis of this material, the significance of this disease was studied, which was considered for long to be of "granulomatous" origin, while it seems to be a peculiar histopathologic type of myocardialgeneration. The cause for this necrosis remains unknown; in spite of as complete as possible investigations in one of the three cases (in which death was preceded for labile recurring lung infiltrates during eleven months) no cause could be demonstrated.
