PROGESSIVE knowledge of histiogenesis and staining methods has solved the diagnostic problems of many jaw lesions but has done little to solve the problems of certain connective tissue lesions of the jawbones. For many years there has been a progressive tendency to diagnose lesions of the jaws demonstrating fibrous tissue proliferation as fibrous dysplasia. Thus, fibrous dysplasia has become a wastebasket term for many fibrous tissue lesions that present diagnostic problems. I will not attempt to discuss all lesions of the jawbones that present fibrous tissue proliferations but will confine my discussion to the diagnostic problems encountered with some of these lesions.

Since much of the controversy that exists relates to fibrous dysplasia, I shall attempt to discuss this term and its meaning to different investigators. Dysplasia implies an abnormal tissue development or hamartoma. Most of the fibrous tissue lesions under discussion do not comply with this definition. It is
