AbstractCarcinoma ex-pleomorphic adenoma is an uncommon tumour of the parotid gland. True malignant mixed tumours of the parotid are rare and we could find only 14 such cases reported. A case of a 76-year-old man diagnosed as suffering from this entity is presented. The diagnosis was based on a series of immunohistochemical studies demonstrating the existence of two separate sarcomatous and carcinomatous elements. The clinical and histological data are presented and the literature is reviewed.

AbstractSpindle cell carcinomas of the salivary gland are extremely rare, with only a few cases having been previously reported. We present a 55-year-old man with a rapidly enlarging mass in the left parotid gland. Despite radical surgery, the tumour recurred, and led to death 11 months later. Histopathologically, the tumour was composed of two components, a squamous cell carcinoma component and a spindle cell sarcomatoid component. A diagnosis of primary spindle cell carcinoma of the parotid gland was made. Immunohistochemical studies revealed keratin positivity and vimentin negativity in the squamous cell carcinoma component: the spindle cell sarcomatoid component was positive for vimentin and negative for keratin, but showed focal positivity for epithelial membrane antigen. The origin of the sarcomatoid component and the differential diagnosis from malignant mixed tumours are discussed.

Abstract‘Benign metastasizing mixed tumours’ are enigmatic lesions of the parotid gland. The authors, through the illustrations of a case and review of the literature, conclude that the tumours are unrecognized and currently unclassified malignancies.

Pleomorphic adenomas account for the majority of parotid masses, typically arising in the tail of the gland and enlarging slowly. Most are 2 to 6 cm in size when resected. We report the resection of a benign mixed tumour of the left parotid gland with a history of bleeding. The resected tumour measured 21 cm in diameter, weighed 1.81 kg, and on pathologic examination was a benign mixed tumour without malignant degeneration. The implications of this unusual case for the management of mixed tumours are discussed with a review of the literature.

Parotid glands were obtained from five adult (four male and one female) armadillos (Dasypus novemcinctus) which were perfusion-fixed. The glands were located in a position similar to that of most mammals. They extended interiorly to the anterior portion of the submandibular gland.In the light microscope, it was noted that the acini were relatively small and stained strongly positive with the periodic acid-Schiff (PAS) and alcian blue techniques, confirming the earlier results of Shackleford (1). Based on these qualities and other structural criteria, these cells have been classified as seromucous (2). The duct system was well developed. There were numerous intercalated ducts and intralobular striated ducts. The striated duct cells contained large amounts of PAS-positive substance.Thin sections revealed that the acinar cells were pyramidal in shape and contained a basally placed, slightly flattened nucleus (Fig. 1). The rough endoplasmic reticulum was also at the base of the cell.
