BACKGROUND Synovial sarcoma is a rare soft tissue sarcoma in the head and neck region and parapharyngeal space. There is no previous cytologic report of synovial sarcoma of parapharynx. The cytologic and immunocytochemical findings of a parapharyngeal biphasic synovial sarcoma together with diagnostic pitfalls are described. CASE REPORT A 21-year-old girl presented with a 6-month history of p...

A few series of parapharyngeal space tumours have been reported earlier but recently not many series have been published in English literature. It is rare for any medical center, let alone an individual surgeon, to develop sufficient experience in evaluating these tumours. We present our experience in the treatment of 41 cases of parapharyngeal tumours from January 1992 to December 2001. FNAC, ...

SUMMARY We report the MR findings of parapharyngeal branchial cleft cyst manifesting as multiple, lower cranial nerve palsies in a 35-year-old woman. On MR images, a well-marginated cystic mass was detected in the right parapharyngeal space, with displacement of both the right internal carotid artery and the right internal jugular vein on the posterolateral side. The cyst contained a whitish fl...

Neurofibroma of the parapharyngeal space accounts for less than 2% of all parapharyngeal space neoplasms. A 38-year-old man presented with complaints of snoring and left-sided nasal obstruction. Medical history also revealed numerous huge skin neurofibromas and multiple café au lait spots all over the body. Pharyngeal endoscopic examination disclosed a firm, nonpulsatile submucosal mass, pushin...

of the salivary gland, accounting for 2% of all primary salivary gland tumors. Histologically, it consists of monomorphic basaloid epithelial cells without a myxochondroid stromal component, which distinguishes it from the pleomorphic adenoma (1, 2). It occurs most frequently in the parotid gland, uncommonly in the oral cavity, upper and lower lip, hard palate, and submandibular gland (3). Ther...

A 66-year-old woman reported fullness in the right ear for 6 months before admission. A submucosal mass shown by MR imaging and CT to arise in the prestyloid parapharyngeal space was the cause of her symptoms. Histologically, the mass proved to be a rhabdomyoma, a rare benign neoplasm, that arose from the muscular wall of the pharynx.

A newborn had an extracerebral, intracranial mass extending from the right middle cranial fossa through the base of the skull to the parapharyngeal space. The mass was predominantly composed of immature brain tissue. It was enclosed by its own leptomeninges and dura and was classified as a glioneural hamartoma.
