Abstract
During the past decade several authors1,6 have reviewed the scientific literature pertaining to midline lethal granuloma, and their efforts have culminated in a detailed description of the characteristic clinical picture and in an extensive evaluation of the available therapeutic modalities. While the etiology of midline lethal granuloma continues to remain a mystery, there is an increased tendency to regard this dread malady as a collagen disease related to periarteritis nodosa.16,21 The location of the major clinical manifestation strongly supports such a hypothesis, for the structures near the median line of the face are supplied by a rich network of smaller blood vessels. A breakdown in the normal defense mechanism of these tissues results in the formation of a granuloma whereas involvement of larger blood vessels leads to extensive destruction and necrosis. Recent experiments by Hans Selye17 focus additional light on the development of allergic phenomena. Without
