The general character and quality of the work done in each of the three departments are regularly inspected and reported on by the members of the advisory com¬ mittee. _ ABSTRACT OF DISCUSSION Dr. John Osborn Polak, Brooklyn : This paper shows what may be accomplished by the combination of obstetrics and gynecology under one head. By combining these two departments the service rendered is improved and fundamental pathology in women becomes better understood, which entitles us to recognition even from the general surgeon. Dr. Holden has presented the organization in a city hospital, and in our organization at the Long Island College Hospital we have the same general plan of one head, controlling both depart¬ ments, a resident and an intern staff. From my experience of twenty odd years, hospital obstetrics cannot be well done without the assistance of trained help. The intern after two or three months of obstetrics does more harm and as bad work as the ordinary practitioner. With the resident system

The present report describes a rare case of spontaneous tumor of the salivary gland in a male Sprague-Dawley rat. The clinically confirmed mass rapidly developed in the cervical region between 19 and 21 weeks of age, and the animal was subsequently euthanized. At necropsy, a well-circumscribed nodule approximately 7 × 6 cm in diameter was found at the site of the salivary gland. The cut surface of the nodule was lobulated and soft and had a pinkish tan fish-flesh appearance. One large cyst (approximately 3 × 2 cm in size) containing reddish fluid was also present in the nodule. Histopathologically, the tumor, with a partially lobulated structure, was surrounded by a thin fibrous capsule. The majority of tumor cells formed a diffuse solid sheet structure that mainly consisted of small ovoid or spindle-shaped cells. In the tumor periphery, some cells were arranged in nest-like structures. Small duct-like structures lined with a monolayer of cuboidal epithelial cells resembling an intercalated duct or large polygonal clear cells with a myoepithelial component were also observed. Mitotic figures and necrotic foci were frequently observed in solid areas. Immunohistochemically, the tumor cells were positive for cytokeratin, epithelial membrane antigen, vimentin, p63, α-smooth muscle actin and calponin. The cells were negative for calcitonin, synaptophysin and chromogranin A. On the basis of these findings, the tumor was diagnosed as an epithelial-myoepithelial carcinoma originating from the luminal epithelial cells and myoepithelial cells in the submandibular gland.
