Epithelial Myoepithelial Carcinoma

The diagnosis and classification of salivary gland tumours is complicated by the wide variety of histological types that exist. Many authors attribute this complexity to the myoepithelial component of these tumours. The objective of this study is to evaluate the histological and immunohistochemical properties of a parotid gland myoepithelioma, in order to further our understanding of the differential diagnosis of salivary gland tumours which contain myoepitheliocytes. Histological specimens were analyzed using haematoxylin and eosin (H&E), periodic acid Schiff (PAS), Cason, Alcian blue, toluidine blue, a-SMA, p63 and ki67. The tumour examined was completely encapsulated, with solid cellular regions delimitated by a stroma. The stroma consisted of wide acidophilic and PAS-positive hyaline septae with areas of metachromasia. The tumour cells contained clear cytoplasm and round nuclei with lax chromatin, although some had more elongated nuclei and occasional dense chromatin. Neither cellular atypia nor mitotic figures were observed. Immunostaining was positive for a-SMA and p63, while it was negative for ki67. The histological characteristics of the tumour analyzed were consistent with a benign myoepithelioma, a rare tumour which represents less than 1% of salivary gland neoplasias. Immunostaining confirmed the morphological diagnosis of myoepithelioma. The absence of cytological changes and mitosis and its encapsulation differentiate it from its malignant counterpart. In comparison to pleomorphic adenoma, the myoepithelioma does not demonstrate ductal differentiation or chondromyxoid stroma. Importantly, the epithelial-myoepithelial carcinoma does develop tubular structures not seen in myoepithelioma. p63, which may act as an oncogene, is expressed within the nuclei of myoepitheliocytes of normal salivary glands. Its expression is retained in tumour myoepitheliocytes and thus it may play a role in oncogenesis.

Sialadenoma Papilliferum

AbstractObjective:We report a rare case of sialadenoma papilliferum.Method:A case report of sialadenoma papilliferum is presented.Results:A 67-year-old woman presented with recurrent epistaxis. She was found to have an exophytic, well circumscribed mass on the nasal septum mucosa. The lesion was completely excised. A diagnosis of sialadenoma papilliferum was made based on the characteristic histological pattern. Follow up showed no evidence of recurrence. Subsequently, the patient remained well without complaint of epistaxis.Conclusion:To our knowledge, this is the first report in the world literature of sialadenoma papilliferum of the nasal cavity. This case indicates that this rare tumour can present with epistaxis, and can be resolved by means of total excision.

This case report demonstrates the management of a myoepithelioma in the minor salivary glands of the palate. Myoepitheliomas are rare, benign, salivary gland tumours which usually affect the parotid glands. The rare neoplasms only account for 1–1.5% of all salivary gland neoplasms. This case shows a minimal approach to treating this rare tumour found in a rare site. CPD/Clinical Relevance: This case demonstrates the potential for rapid epithelial recovery within the oral cavity.

Ductal papillomas have unique papillary features arising from the salivary gland duct system. They comprise three rare benign adenomas, namely, inverted ductal papilloma, sialadenoma papilliferum, and intraductal papilloma. Intraductal papilloma is an extremely rare benign salivary gland tumor that occurs most commonly in the minor salivary glands. Here, we are presenting a case report of intraductal papilloma in an 18-year-old patient.
