Introduction: Minor salivary gland tumors are relatively rare, but have a higher chance of malignancy than major salivary gland tumors. The palate appears to be the most commonly involved site. The most frequent benign tumor is the pleomorphic adenoma. Case report: We report a case of a pleomorphic adenoma, which occurred in the hard and soft palate of a 34-year-old female and presented as an a...

Among salivary gland neoplasms, metastasizing pleomorphic adenoma (MPA) constitutes an extremely rare group of tumors. The present paper reports a case of pleomorphic adenoma (PA) in submandibular gland that, after more than 30 years of initial treatment, recurred and metastasized to ipsilateral neck lymph nodes and parotid gland. In an attempt to elucidate the malignant behavior of metastasizi...

We report a case of pleomorphic adenoma of the trachea in an 8-year-old boy who required emergency surgery for severe respiratory distress. Chest computed tomographic scan and bronchoscopy showed a relatively large mass in distal trachea and right main bronchus and destruction of the lung parenchyma. The patient was subjected to right carinal resection, pneumonectomy, and pericardial patch trac...

Further noncontrast CT scan was performed, which revealed well-defined, well-circumscribed smooth marginated solid cystic lesion in superficial and deep lobes of left parotid gland, predominantly in posteroinferior part of gland, medially the lesion extends into stylomandibular tunnel (Figure 1). On postcontrast CT, irregular nodular enhancement of solid part was noted and in close relation to ...

Parapharyngeal space masses account for 0.5% of all head and neck neoplasms. Pleomorphic adenoma arising from the epithelial rests of the salivary tissue in the parapharyngeal space is rare. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) allows a precise topographical localization of the mass and the diagnosis of its nature in the majority of cases. Treatment of parapharyngeal pl...

Carcinoma ex-pleomorphic adenoma (CXPA) is a rare, destructive, poorly understood malignancy of the salivary gland. CXPA is described as a carcinoma arising from a primary (de novo) or recurrent benign pleomorphic adenoma (PA). It is most likely to occur within the major salivary glands, mostly parotid gland and usually occurs in patients in the 6th– 8th decades of life, approximately one decad...

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...

We present 4 cases of carcinoma ex pleomorphic adenoma of the parotid gland. In 3 of the 4 cases, diffusion-weighted and apparent diffusion coefficient (ADC) mapping images clearly revealed carcinoma as a hypercellular area with low ADC values and pleomorphic adenoma as a hypocellular area with high ADC values. Diffusion-weighted images demonstrated well complex tissue components in carcinoma e...
