Ringertz'128 monograph is based on a study of the pathologic material of Sabbatsberg's Oto-laryngological Clinic and Radiumhemmet of Stockholm as well as a large material drawn from outlying districts. Between 1921 and 1935, 391 patients with malignant tumors of the sinuses were treated. The clinical observations have been discussed by Oehngren, Holmgren, Berven and Ahlbom in previous publications. Nineteen different types of tumor were found, squamous cell carcinoma being found in the largest single group, numbering 218. The article, which is well illustrated, is replete with descriptions of various types of tumors, particularly the unusual tumors, such as cylindroma, reticulocytoma, plasmocytoma, Ewing's tumor and malignant melanoma. A brief clinical record of each of the 391 cases is extremely helpful in evaluating the histopathologic observations as described by the author. The monograph is an excellent piece of work, worthy of study, and should prove very useful for reference.
