A case of an 87-year-old female with pleomorphic adenoma of the tongue base is reported, with a review of the literature. The tumour had enlarged gradually over a period of three years, causing dysphagia and dysphasia. Computed tomography and magnetic resonance imaging showed that the tumour was exophytic and occupy the oropharynx with little extension into the muscle tissue. The tumour was resected by CO2 laser. Histological examination revealed a benign pleomorphic adenoma that originated from the minor salivary gland of the tongue base.

The pleomorphic adenoma is the most common benign tumor of the minor salivary glands and is comprised of epithelial and mesenchymal tissues. The majority of the salivary gland tumors occur in the second decade of life with a slight predilection for females. Clinically it presents as a firm or rubbery submucosal mass without ulceration or surrounding inflammation. Diagnosis is established on the clinical examination and histopathology, supplemented with plane radiographs, computerized tomography, and magnetic resonance imaging when necessary. Here, we report a case of pleomorphic adenoma of the hard palate in a 21-year-old female patient with a painless swelling in the left palatal region of nine months duration.

ABSTRACT Pleomorphic adenoma is a benign tumor of the salivary glands, most commonly affecting the parotid gland. Pleomorphic adenoma of the ear is rare. The use of imaging modalities, especially magnetic resonance imaging (MRI), is particularly useful in localizing and surgical planning of these tumors. We present a case of pleomorphic adenoma invading the mastoid cortical bone, with review of literature. How to cite this article Vamanshankar H, Parida PK.

Acoustic rhinometry (AR) evaluates the geometry of the nasal cavity with acoustic reflections and provides information about nasal cross-sectional areas (CSA) and nasal volume within a given distance. The accuracy of the information obtained by AR was compared with that of magnetic resonance imaging (MRI) of the nasal cavity. Five healthy subjects were evaluated with AR and the MRI before and after the application of a long-acting nasal decongestant spray, to eliminate possible interference of the nasal cycle with both measurement techniques. The MRI images of 2 mm coronal sections of the nasal cavity were traced by three independent observers and the CSAs were calculated by computer-aided imaging digitization, to be compared with the calculated CSAs obtained with the AR at the corresponding distance from the nasal tip. Digitized data from the MRI images were also used to calculate the nasal volume within the first 6 cm from the nasal tip and compared with the AR volume measurements. The interobserver variation of digitized MRI data predecongestant and postdecongestant was not significant. The correlations of CSA and volume measurements between the AR and MRI were high (0.969) after the application of the decongestant. The correlation between the AR and MRI measurements before the decongestant was low (0.345). This may have been the result of interference of the nasal cycle during the long MRI measurements (1 hour) or other unknown factors. We conclude that AR measurements of nasal CSAs and volumes provide accurate information when compared with the MRI of the decongested nasal airway.

AbstractBenign salivary gland tumours in childhood are rare. We present a case of a pleomorphic adenoma arising in a minor salivary gland within the hard palate, review the literature and discuss the diagnostic and therapeutic features of the condition.
