The Authors consider the following problems associated with cervical salivary cysts: incidence, distribution, diagnosis, cause, pathology, treatment and results of treatment. They present detailed comments on the prospects of success using a line of treatment modified from that originally &&bed by Berge (1938) and more recently described by Kealy (1964). I N T R O D U C T I O NALTHOUGH salivary cysts are the commonest conditions of salivary glands that veterinary surgeons are called upon to treat, the incidence of the condition is relatively low; only one case in approximately 4000 patients that attend the Small Animal Clinic at the University of Edinburgh Veterinary School suffers from the complaint; none the less the condition is important because of its intractable nature.Study of the problem is difficult, not only because cases are relatively scarce, but also because the terminology used in most anatomy text-books is confusing and because their descriptions of the salivary glands in the dog are inaccurate. The pathology of the condition is indefinite and none of the treatments currently described give consistently satisfactory results. Recent publications on this subject by Berge and Westhues (1961), Spreull et al. (1964), Kealy (1964), Hulland and Archibald (1964) and Spreull (1965) still leave many interesting and important aspects of this condition unsolved. This publication establishes some of these special problems and contributes to their solution.

During the period from January 1969 to January 1975, twenty‐five cases of malignant haemangioendothelioma were found in the course of routine post‐mortem examinations. One case was observed in the period 1949–1952. The two periods are compared with respect to age, breed and sex of dogs examined. The Alsatian was represented significantly more than other breeds (eleven out of twenty‐five cases) and particularly in cases involving the right atrium (seven Alsatians in a total of eleven cases). The post‐mortem findings and histology are described. It is suggested that there are three groups of cases, namely, primary spleen, primary right atrium and primary at some other site.
