Eosinophilic granuloma of the jaws: An analysis of clinical and radiographic presentation

SummaryEosinophilic granuloma (EG) is the localized and mildest form of histiocytosis-X group of diseases. In this study, 22 patients of pathologically proven EG involving the jaws were retrospectively studied concerning the clinical and radiographic presentation. The clinical and radiographic presentation of the 22 cases was quite varied, and the accuracy of clinical and radiographic diagnosis was low. However, the clinical and radiographic presentation correlated with the lesion site, and accordingly all the jaw lesions could be divided into three types (Alveolar Type, Intraosseous Type, and Mixed Type). Our classification based on the lesion sites reveals the correlation between the clinical and radiographic presentation of EG and the lesion sites, and may be useful in the identification of lesions of EG in the jaws.
