[Nosologic criteria for the classification of midfacial granulomatosis]

The authors report three cases of Stewart's disease and five cases of Wegener's disease seen over a period of 10 years, during which time they saw no cases of non-Hodgkins malignant lymphoma presenting as a mid-facial malignant granuloma. On the basis of these cases together with a review of the literature, they argue in favour of the dissociation of Stewart and Wegener as well as that of Stewart and monomorphous NHML, raising the problem of the existence of the latter as an entity.
