RARE CASE OF PARAPHARYNGIAL TUMOR OF THE PAROTID SALIVARY GLAND

Abstract

According to the literature tumours of the parotid salivary gland among other neoplasms make up 1.2%. Localization in the pharyngeal section of the parotid salivary gland is 5.4%. (Paches A.M. 1958). A sufficient rarity of a parapharyngial tumor requires differentiation from neurinoma, carotid artery aneurysm of this location.The article describes a rare case of parapharyngial tumor detected in a woman E. at the age of 56 years. A tumor formation inthe mouth area grew without significant worries for 7 years. The patient associates the appearance of a neoplasm with a catarrhal disease. She was consulted by an oncologist. A cytological study number 1107 from 10.01.2020 made it possible to diagnose a mixed tumor of the pharyngeal process of the right parotid salivary gland. On MRI of the soft tissues of the head dated 23.12.2019, a volumetric formation with clear tuberous contours 33x35x57 mm in size was revealed in the pharyngeal region of the right heterogeneous structure. The formation lies behind the branch of the lower jaw, anterior to the common carotid artery, can not be clearly differentiated from the right jugular vein. The airway of the oropharynx is compressed.Ultrasound of the lymph nodes of the neck from 19.12.2019 showed ultrasound signs of reactive cervical lymphadenopathy. In the right submandibular and parotid region, the volume hypoechoic formation of 66x59x68 (volume 127 cm3), uneven, clear, heterogeneous.
