11/22. Cytomorphologic features of the rare epithelial-myoepithelial carcinoma of the salivary gland.

    The cytomorphologic features of an epithelial-myoepithelial carcinoma arising in the submandibular gland are reported. The aspiration smears were cellular, with two cell types present: dark cells showing attempted gland formation and clear cells with vacuolization. The clear cells frequently formed globular masses and had indistinct cytoplasmic membranes. These globular masses of clear cells were usually adjacent to the fragments of dark cells. A striking feature was the presence of numerous naked nuclei.

12/22. Second primary tumour following retinoblastoma.

    Reported is a child who at the age of 18 months had presented with a left retinoblastoma. The lesion had involved the optic nerve (Stage IV), and was successfully treated by enucleation and radiotherapy. The radiation field did not include the mandible or the submandibular triangle. He was followed up until he left the area aged 11 years. He represented aged 12 years with a progressive swelling of the left submandibular gland. histology of the surgically excised submandibular gland revealed a mucoepidermoid carcinoma of the submandibular gland. This case highlights the need for continual surveillance in survivors of retinoblastoma, as second primary tumours occur both within and outside of previous radiation fields. The clinical association between retinoblastoma and mucoepidermoid carcinoma of the submandibular gland has not been previously reported.

13/22. 'Malignant lymphoepithelial lesions' (undifferentiated ductal carcinomas of the parotid gland). Three case reports and review of the literature.

    Three cases of the so-cassed malignant lymphoepithelial lesion occurring in women are described. The authors, however, prefer to label the lesion 'undifferentiated carcinoma of the parotid'. From an accurate review of the world literature it appears that 23 cases of such lesion have been reported, 22 arising in the parotid and 1 in the submandibular gland. The malignant lymphoepithelial lesion has been mainly encountered in Eskimos and the three cases of the present report are the first to have been evidenced in europe. The malignant lymphoepithelial lesion is discussed from the taxonomic, nosologic, pathogenetic, diagnostic and therapeutic points of view. The lesion does not seem to be of an autoimmune nature, unlike the benign lymphoepithelial lesion which is generally regarded as an autoimmune disease.

14/22. Surgical management of the mass in the buccal space.

    The discovery of a mass in the buccal space provides a diagnostic and therapeutic challenge. A common approach for the removal of the mass in the buccal space has been through the oral cavity. However, there is an ever-present danger of injury to the facial nerve and Stensen's duct with this approach. Experience with tumors in this area prompted a review of the anatomy of the buccal space and resulted in an improvement in the surgical technique. Our external approach through an extended parotid-submandibular incision provides excellent exposure which minimizes the risk of complications during excision of these tumors and provides an excellent cosmetic result.

15/22. Spindle cell mucoepidermoid carcinoma of submandibular gland.

    A malignant tumor of the submandibular gland was found to consist predominately of spindle cell elements that initially suggested a primary sarcoma. Further examination revealed that the spindled malignant cells were derived from a high-grade mucoepidermoid carcinoma.

16/22. Mucoepidermoid carcinoma of the salivary gland in pleural fluid. A case report.

    The cellular features of mucoepidermoid carcinoma of submandibular gland origin observed in pleural fluid are presented. The pleural fluid contained predominantly atypical spheroid cell clusters accompanied by numerous mesothelial cells. The cells had round nuclei with conspicuous nucleoli, coarsely granular chromatin and abundant cytoplasm with vacuoles. The cellular features of the malignant cells in the pleural fluid were correlated with the histology of the parent lesion.

17/22. Metastasis to the submaxillary gland from the breast - a case report and literature review.

    Most series of submandibular gland tumors include a 50 per cent incidence of malignancy. However, very few reports of metastases to the submaxillary gland have appeared. This report documents a case of carcinoma of the breast which metastasized to the submaxillary gland 19 years following the appearance of the primary. diagnosis was confirmed by immunofluorescence and estrogen and progesterone binding proteins. This report represents the eighth reported case of metastases to the submaxillary gland from a non head and neck primary. Although this occurrence is a rarity, those dealing with head and neck malignancies should be aware of its existence. The significance of the estrogen binding proteins and immunofluorescent diagnostic techniques is discussed.

18/22. Familial carcinoma of the submandibular gland. A case report and an epidemiologic review.

    Cases of submandibular carcinomas in two siblings are reported. A familial occurrence of submandibular gland neoplasms has not been previously reported. Postulated causes and predisposing factors in salivary neoplasms are reviewed. None of these theories explains the cause of the unusual familial occurrence of the neoplasms in these cases.

19/22. Clear cell epithelial-myoepithelial carcinoma arising in pleomorphic adenoma of the lacrimal gland.

    BACKGROUND: A 63-year-old man had an 8-year history of painless proptosis, which had noticeably increased over the last 2 months. A mass was palpable in the left lateral canthus. Computed tomographic studies showed a globular mass with small foci of calcification involving the lacrimal gland. After an incisional biopsy, a histologic diagnosis of clear cell epithelial-myoepithelial carcinoma was made and an orbital exenteration was performed. FINDINGS: Results of histologic examination of the mass showed a partially encapsulated, clear cell epithelial-myoepithelial carcinoma with an associated pleomorphic adenoma (benign mixed tumor). Immunohistochemical studies disclosed strong immunoreactivity to cytokeratin (AE1/AE3), epithelial membrane antigen, S-100 protein, and alpha-actin. CONCLUSION: Although a clear cell myoepithelial carcinoma rarely has been reported in association with a pleomorphic adenoma of the submandibular gland, to the authors' knowledge, this combination has never been reported in the lacrimal gland, nor has a clear cell epithelial-myoepithelial carcinoma ever been reported in this anatomic location. The differential diagnosis of lesions with prominent clear cells involving the lacrimal gland is extensive and includes clear cell variants of acinic cell carcinoma and oncocytoma, mucoepidermoid carcinoma, and others.

20/22. Sarcoid reaction in thyroid diseases: report of a case of thyroid carcinoma demonstrating sarcoid reaction in regional lymph nodes.

    We describe an extremely rare case of thyroid carcinoma accompanied by sarcoid reaction in regional lymph nodes. The patient, a 40-year-old woman, was found to have anterior neck swelling during a routine medical examination. physical examination revealed a bad movable and firm nodule measuring 3.5 x 2.5 cm in the right thyroid lobe. Examination of a fine-needle aspiration cytology of the nodule suggested papillary carcinoma of class V. Right lobectomy and isthmectomy with neck dissection were performed. Histopathological examination of the resected specimens revealed papillary carcinoma accompanied by metastatic foci in right perithyroidal lymph nodes and non-caseous sarcoid-like granulomas in pretracheal, right upper internal deep cervical and submandibular lymph nodes. We concluded that these granulomas were due to a sarcoid reaction associated with thyroid carcinoma, after performing examinations to rule out the possibility of systemic sarcoidosis.
