Metastasis is a feature of malignant neoplasms. Although rare, metastasizing pathologically benign mixed tumour has been reported. This report describes a 33-year-old woman with multiple lung metastases from mixed tumour. A small preauricular mass had been removed 23 years earlier. Six years later, the patient had the same symptom; the recurrent mass was resected. She was not aware of the exact pathological diagnosis of the previous tumours. One of the most common features of metastasizing mixed tumour is recurrence at the primary site. Inadequate resection of the primary tumour is often associated with metastasis. Thus, it is important for the head and neck surgeon to be aware of the concept of pathologically benign metastasizing mixed tumour and the importance of adequate surgical procedure.

Abstract Considering the confusion in the literature regarding local recurrence, spread, or metastases of pleomorphic adenoma (PA) in the head and neck region, the aim of this study was to enhance understanding of the characteristics of metastasizing pleomorphic adenoma (MPA) by reviewing the literature and presenting a case. English language articles with proof of metastases were included in the literature review. Of the 80 cases in the literature with MPA, 46 were female and 33 were male (sex ...

Pleomorphic adenoma (PA) is the most common salivary gland neoplasm. On a molecular level PA is characterized by a translocation involving PLAG1 or HMGA2. PA is considered to be a benign tumor although it can undergo malignant transformation. Alternatively, cases of histologically benign PA “metasta

Tobacco is implicated in multisystemic carcinogenesis through more than fifty identified carcinogenic metabolites that produce mutations responsible for alterations in cell cycle, immune response and endocrine regulation. Is one of nine risk factors identified in one third of cancer deaths together with obesity, sedentary, alcohol consumption, sexual promiscuity, drug addiction, and open and closed air contamination. Answering for cardiovascular diseases as the first cause of death in civilized ...

Background: Pleomorphic adenoma (PA) is the commonest benign neoplasm of salivary glands. 1 PA can undergo malignant transformation to ex-pleomorphic adenoma 2,3 but rarely, can metastasise without malignant transformation. 4,5 Metastasising pleomorphic adenoma (MPA) is a rare malignant tumour which, histologically, is indistinguishable from PA yet produces secondary tumours in distant sites. 6,7,8 Objective: Our aim is to review the literature for all reported cases of MPA and create a virtual ...

Pleomorphic adenoma (mixed tumor) is the most common neoplasm of the salivary gland. It is usually a benign, slow-growing and well-circumscribed tumor. However, there are rare reports of a subset of these tumors metastasizing to distant sites without undergoing malignant transformation. Here we describe a case of pleomorphic adenoma of the parotid gland that metastasied to the cervical lymph node coincidentally with similar appearance of the primary lesion in the ipsilateral parotid gland. Case ...

Pleomorphic adenoma (PA), also known as mixed tumor, is the most common benign salivary gland neoplasm, characterized histologically by both epithelial and mesenchymal elements. Approximately 75% of PAs occur in the parotid gland, followed by the submandibular gland (15%) and minor glands of the palate and nasal septum (10%). Less common is the occurrence in the minor glands of the upper lip, cheek, floor of mouth, larynx, and trachea. Malignant mixed tumors encompassing the entities, carcinoma ...

Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands and is generally accepted as benign biologically. Occasionally PA may give rise to metastasis. The metastasis may develop in a PA in which a malignant transformation occurs, either arising a carcinoma in the PA (carcinoma ex-mixed tumour) or as a carcinosarcoma (so–called true malignant mixed tumour). However, very rare benign PA eventually metastasise, usually after having a previous rec...

Lung “metastases” of benign meningiomas are rarely described events of biological and clinical interest. We, here, report of a 70-year-old healthy woman found by CT scan to have multiple lesions, the two largest in the right lung on routine examination. Anamnesis revealed that the patient underwent a surgical resection of cerebral meningioma 12 years before. The larger lung lesion was a 3-cm node located in the right lung and was removed by wedge resection. Macroscopically, it showed well-define...
