This is a well-organized treatment of a difficult problem. Various phases of the problem are discussed, from the embryology of the salivary glands to differential diagnosis and treatment of their tumors. There is an extensive bibliography. The discussion of the author's own cases accompanied by photomicrographs is instructive. In a work as comprehensive as this, it is surprising that mumps is not considered in the differential diagnosis and that the postoperative insertion of a filiform bougie into the parotid gland is not mentioned. This book should be helpful to the surgeon faced with a parotid problem, regardless of his experience.
