Recurrent Pleomorphic Adenoma of the Parotid Gland
This is a retrospective analysis of 35 patients treated for a first recurrence of pleomorphic adenoma of the parotid gland from 1982 to 1997. All patients were treated surgically; no patient received radiotherapy for benign disease. We experienced a locoregional control rate of 77%. Our malignant transformation rate was 5.7%. Our results suggest that in carefully selected patients, local excisi...
متن کاملClinical Manifestations of Recurrent Parotid Pleomorphic Adenoma
OBJECTIVES This study was undertaken to confirm the clinical characteristics of recurrent pleomorphic adenoma (RPA), and to identify those factors that affect the development of malignant transformation (MT) from RPA. METHODS The medical records of 270 patients, who were operated upon for parotid PA, were retrospectively reviewed. The pathologic specimens of a selected series of 23 patients w...
متن کاملRecurrent Pleomorphic Adenoma of the Submandibular Gland.
Pleomorphic adenoma (PA) is the most common benign tumor of salivary glands. Most PAs occur in the parotid (80%), followed by the submandibular gland (10%) and minor salivary and sublingual glands (10%). Submandibular gland PAs usually manifest in the submandibular area as a painless hard mass. Although several recurrent parotid gland PA cases have been reported in the literature, recurrent sub...
متن کاملCarcinoma ex-pleomorphic adenoma derived from recurrent pleomorphic adenoma shows important difference by array CGH compared to recurrent pleomorphic adenoma without malignant transformation.
INTRODUCTION A key step of cancer development is the progressive accumulation of genomic changes resulting in disruption of several biological mechanisms. Carcinoma ex-pleomorphic adenoma (CXPA) is an aggressive neoplasm that arises from a pleomorphic adenoma. CXPA derived from a recurrent PA (RPA) has been rarely reported, and the genomic changes associated with these tumors have not yet been ...
متن کاملMulticentric recurrent parotid pleomorphic adenoma in a child.
Mixed tumours of the parotid gland are rare in childhood and recurrence of this tumour is infrequent. Some authors report a higher rate of recurrence with some histological subtypes, like hypocellular variant. Female sex and young age at initial treatment are also risk factor for recurrence. Also the first surgical treatment, tumour enucleation or parotidectomy, has been implicated as a cause f...
