“…The age ranged from 15-55 years with Male: Female ratio was 1:1. Maran et al (8) and Pang et al(12) also reported no sex predominance in their studies. The most common mode of presentation http://www.pacificejournals.com/aabs was gradually increasing painless mass in neck, the other symptoms being foreign body sensation, dysphagia, hoarseness of voice and impaired hearing (Table I).…”

Parapharyngeal space tumors (PPS) are rare, representing only 0.5% of head and neck neoplasm. 7 patients diagnosed with PPS tumors which presented to us within a span of two years were included. Cytopathologic evaluation was done by fine needle aspiration cytology, computed tomography and ultrasonography guidance wherever necessary. Histopathology confirmation was available in all the cases. The age of the patient ranged from 15-55 years with male to female ratio 1:1. The commonest clinical presentation was a slowly increasing painless mass in neck. Out of 7 cases the tumors encountered were pleomorphic adenoma (02), neurofibroma (01), Schwannoma (01), Paraganglioma (01), Lipoma (01), Angiofibroma (01). Two false negative cases were encountered. Overall diagnostic accuracy being 71.4%.With proper clinical and radiological assessment, FNAC can be extremely useful in diagnosing most of these lesions except a few which need histopathological confirmation.

“…It is usually seen as a metastatic nodal disease or less commonly as an extension of deep lobe parotid tumor into the parapharyngeal space. Som et al [11] and Maran et al [12] have reported an incidence of 14% and 17% respectively. Rarely, primary PPS tumours can arise from lateral pharyngeal wall or minor salivary gland tissue of PPS (SCC comprises 1.2% of minor salivary gland epithelial neoplasms) [13,14].…”

BackgroundParapharyngeal space (PPS) tumors are rare, accounting for 0.5% of all neoplasms of head and neck. PPS tumors may be primary, metastatic or a direct extension of tumors from the adjacent spaces. The frequency of benign and malignant tumors is about 80% and 20%, respectively. Most of them originate from the salivary gland (40-50%), followed by a neurogenic etiology and the remainder are a broad spectrum of miscellaneous tumors [1][2][3][4][5][6][7].The PPS is a lateral pharyngeal region. It is divided by muscular aponeurotic partition into an anterior (prestyloid) muscular compartment and a posterior (poststyloid) neurovascular compartment [1,[3][4][5][6][7]. Imaging is crucial for the assessment of PPS tumors. Surgery is performed based on information provided by these diagnostic modalities.This article will present a case of left parapharyngeal squamos cell carcinoma with unusual spinal metastases, and the potential role of FDG PET/CT will be illustrated. Case PresentationA 36-year-old male patient who showed up in April 2016 with 3 months' history of left side facial paralysis, left trismus, difficulty in swallowing and otological symptoms: otorrhea and otorrhagia. For the last month, he had developed a pharyngeal cavity mass. CT scan head and neck showed well defined heterogeneously enhancing left parapharyngeal solid mass (32×50×62 mm) with multiple area of necrosis, bulging into nasopharynx with extension to pharyngeal mucosal surface.The mass overwhelms the tympanic cavity and spreads to the ipsilateral external auditory meatus and pterygoid muscle. It causes the AbstractBackground: Tumors of the parapharyngeal space (PPS) are rare and account for only 0.5% of head and neck neoplasms. Approximately 80% of these tumors are benign lesions, yet they represent a formidable diagnostic and treatment challenge. They are difficult to diagnose because they have few symptoms, therefore, CT and MRI are essential to delineate the tumor extent, intracranial involvement and relationship to the adjacent vital structures.

“…4, October-December, 1998 [7 383 Tumours of the Parapharyngeal Space-Anita Bhandari et al Peroral approach has been condemned because of the blind surgical approach with increased chances of tumour rupture and subtotal tumour removal, increased risk of infection, risk of injury to facial nerve, risk of hemorrhage and inability to control bleeding. (Work, 1977;Mclean 1976;Maran et al 1984) We did not use the peroral approach in any case. A transparotid approach with facial nerve dissection is essential for all deep lobe tumours.…”

A series of 14 parapharyngeal tumours has been studied with regard to their symptology, pre-operative evaluation and surgical management. High resolution computed tomography is now the best initial diagnostic study because it helps to determine the size and extent of the tumour, differentiate tumours of parotid and extraparotid origin, demonstrate degree oftumour vascularity, separate benign from malignant lesions, plan the surgical approach and predict prognosis.
