It is a benign neoplasm of the nasopharynx.⠀⠀
⠀⠀
✅Adolescents and young adults between 14 and 25 years are affected, and there is a distinct male predominance.⠀⠀
⠀⠀
⏩Based on the clinical and radiological features, JNA is classified into three types.⠀⠀
⠀⠀
✅Type I includes lesions fundamentally localized to the nasal cavity, paranasal sinus, nasopharynx, or pterygopalatine fossa.⠀⠀
✅Type II is a JNA extending into the infratemporal fossa, buccal region, or orbital cavity with anterior and/or minimal middle cranial fossa extension but intact dura mater.⠀⠀
✅Type III is a calabash-like massive tumor lobe in the middle cranial fossa.This tumor originates in the lateral wall of the nasal cavity, close to the superior border of the sphenopalatine foramen.⠀⠀
⠀⠀
⏩The growth initiates in the submucosa of the floor of the nasopharynx extend to the nasal septum and the posterior space of the nose and causes airway obstruction. ⠀⠀
⠀⠀
✅Continuous growth involves the sphenoidal sinus, nasal fossa and middle turbinate, pterygomaxillary fossa and the posterior wall of the maxillary sinus as seen in the present case.⠀⠀
⠀⠀
✅Eventually, the tumor may invade the infratemporal fossa and the middle cranial fossa.⠀⠀
⠀⠀
⏩JNA is benign but locally destructive. ⠀⠀
⠀⠀
✅This may be attributed to a rich vasculature and lack of encapsulation. It impinges on adjacent structures and causes pressure erosion of bone⠀⠀
⠀⠀
⏩JNA classically presents as a painless, progressive unilateral nasal obstruction. Epistaxis, rhinorrhea and pain may also be seen. ⠀⠀
⠀⠀
✅Clinical examination reveals a firm and friable mass in the nasopharynx and nose. As this tumor is aggressive and expansile, it invades adjacent structures causing further symptoms. Impaired Eustachian tube function, facial deformity, proptosis and changes in visual acuity may be seen. ⠀⠀
⠀⠀
✅Invasion of the intracranial region may lead to cranial nerve palsy. 16/12/2022
