Dr Liebow provisionally termed this constellation of findings necrotizing sarcoid granulomatosis (NSG) and stated that "the problem is whether the disease represents necrotizing angiitis with sarcoid reaction, or sarcoidosis with necrosis of the granulomas and of the vessels." (1) In the intervening 4 decades, his questions have not been definitively answered, despite the publication of several large series of patients stated to have NSG (1-8) and numerous reports of individual and small numbers of cases.
In 1973 Liebow (1) expressed his uncertainty about the nature of NSG, stating that "the problem is whether the disease represents necrotizing angiitis with sarcoid reaction, or sarcoidosis with necrosis of the granulomas and of the vessels." I believe that the data presented in this study provide convincing evidence that "sarcoidosis with necrosis of the granulomas and of the vessels" is the correct alternative.
Furthermore, necrotizing angiitis has also been described in adult amphetamine abusers (Citron et al., 1970).
