The earliest known documentation of nasopharyngeal angiofibroma (NA) dates to Hippocrates in the fifth century B.C. Commonly referred to as juvenile nasopharyngeal angiofibroma (JNA), it is also known as juvenile angiofibroma (JAF), or fibromatous or angiofibromatous hamartoma of the nasal cavity Juvenile nasopharyngeal angiofibromas (JNAs) are rare tumors that occur almost exclusively among adolescent males. They are benign, locally invasive tumors with a strong tendency to recur. Surgical resection, when possible, is considered the treatment of choice . Although it is non-malignant (not cancerous), it can expand quickly and extensively
Nasopharyngeal angiofibroma, also known as juvenile nasal angiofibroma, is a histologically benign but locally aggressive vascular tumor of the nasopharynx that arises from the superior margin of the sphenopalatine foramen and grows in the back of the nasal cavity Angiofibroma is a benign (noncancerous) nasal cavity tumor that almost exclusively affects adolescent boys. It also may be referred to as juvenile nasopharyngeal angiofibroma (JNA). The age range for this disease is 7 to 19 years old, with most people being diagnosed between 10 and 19 years old
The juvenile nasopharyngeal angiofibroma is a benign neoplasm of the posterior nasopharynx. It occurs almost exclusively in adolescent males, with an average age at diagnosis of 15 years old Epidemiology. 0.05 - 0.5% of all head and neck tumors ( StatPearls: Nasopharyngeal Angiofibroma [Accessed 10 June 2020] ) Occurs almost exclusively in adolescent and young males, with a median age of diagnosis of 15 years (range: 8 - 27 years) ( Acta Otorrinolaringol Esp 2019;70:279, Head Neck Pathol 2018;12:52 Nasopharyngeal angiofibroma is a tumor that grows behind the nose. Although it is a benign tumor (not cancerous), it is aggressive and serious. It can spread from the nasal cavity to the sinuses, eye socket, skull and brain. The nasopharyngeal angiofibroma tumor is made mostly of blood vessels, which can result in frequent nosebleeds Juvenile nasopharyngeal angiofibromas are a rare benign, but locally aggressive, vascular tumors that occur almost exclusively in young men. On imaging, they present as a vividly enhancing soft-tissue masses centered on the sphenopalatine foramen. Given its vascularity, prominent flow voids are seen on MRI leading to a salt and pepper appearance Nasopharyngeal angiofibromas (NA) are rare tumor-like lesions characterized by architecturally irregular vessels set in a fibrous stroma
sopharyngeal angiofibroma was 25 times more fre- quent in our patient population with familial adenoma- tous polyposis than in an age-matched hospital population. The association of these two rare condi- tions suggests that nasopharyngeal angiofibroma is an extracolonic manifestation of adenomatous pol- yposis What is a juvenile nasopharyngeal angiofibroma (JNA)? Juvenile nasopharyngeal angiofibroma (JNA), while rare, is the most common benign tumor of the space at the back of the nasal cavity that connects the nose to the mouth. This space is called the nasopharynx
Treatments for Juvenile Nasopharyngeal Angiofibroma. What are the treatment options for juvenile nasopharyngeal angiofibroma? First line therapy is usually surgery, with the goal of removing as much of the tumor as possible. Ideally the entire tumor is removed. In some situations, depending on where the tumor has spread, complete removal may. Juvenile nasopharyngeal angiofibroma (JNA) is an uncommon, slow-growing, benign but locally invasive vascular tumor arising from tissues in the sphenopalatine foramen inside the nasal cavity. JNAs are also reported to arise from the posterior aspect of the middle turbinate and rarely from other sites of the nasal cavity and in paranasal sinuses OBJECTIVES: Juvenile nasopharyngeal angiofibroma (JNA) is a highly vascular and locally invasive tumor with a high incidence of persistence and recurrence. The classical treatment of this tumor is surgery and/or radiotherapy. Use of endoscopic techniques seems to be on the rise in treatment of these lesions Nasopharyngeal angiofibroma Juvenile nasopharyngeal angiofibroma are benign neoplasm consisting of vascular and fibrous tissue. The resected angiofibroma as shown here is a large, single, sessile, red-pinkish mass that previously occupied the nasopharynx. Angiofibromas can also be pedunculated or polypoid
Thirty-two cases of nasopharyngeal angiofibroma, including 2 recurrences, all of which had been excised from males between 7 and 25 years, were subjected to systematic immunohistochemical study. Most of the tumour vessels, which lacked elastic laminae, were characterized by vascular walls of irregular thickness and variable muscle content. In places endothelial cells were only separated from. Nasopharyngeal angiofibroma: (A nine-year experience) - Volume 102 Issue Case Discussion. This is a classical presentation of juvenile nasopharyngeal angiofibroma.This is a histologically benign lesion with very aggressive local behavior. It is almost exclusively encountered in adolescent males 1.The most common presenting symptom is painless nasal obstruction or epistaxis; however, other symptoms may develop depending on the size and extent of the tumor mass

Nasopharyngeal angiofibroma is a histologically benign but locally aggressive vascular tumor of the nasopharynx that arises from the superior margin of the sphenopalatine foramen and grows in the back of the nasal cavity. It most commonly affects adolescent males (because it is a hormone-sensitive tumor). Though it is a benign tumor, it is locally invasive and can invade the nose, cheek, orbit.

These tumors tend to develop in young men between 10 and 25 years old. Androgen hormones can play a part in the growth of these tumors Epistaxis/Juvenile nasopharyngeal angiofibroma (JNA) Overview. Nosebleeds (epistaxis) can occur for a variety of reasons. They may simply be due to dry weather or allergens in the environment. A more serious cause of nosebleeds is related to a tumor called a juvenile nasopharyngeal angiofibroma (JNA)
Nasopharyngeal angiofibroma is a histologically and biologically benign tumor with aggressive behavior due to its location and associated symptoms including significant epistaxis and nasal obstruction (1-5).

Diagnosis If nasopharyngeal angiofibroma is suspected based on physical exam (a smooth submucosal mass in the posterior nasal cavity.
Nasopharyngeal angiofibroma is usually encapsulated and composed of vascular tissue and fibrous stroma with coarse or fine collagen fibers. Vessels are thin-walled, lack elastic fibers, have absent or incomplete smooth muscle, and vary in appearance from stellate or staghorn to barely conspicuous because of stromal compression Juvenile nasopharyngeal angiofibroma is a benign disease affecting young males with a propensity to invade intracranially and into the orbit along preformed pathways. Complete surgical excision is the mainstay of management. Patients with multiple recurrences along with tumour extension into skull base and orbit can be considered for external beam radiation as either adjuvant or definitive.

Juvenile nasopharyngeal angiofibroma is the most common benign tumour of the nasopharynx It is usually seen in males in the second decade of life and usually presents with recurrent profuse epistaxis Etiology: Since it occurs in the second decade of life, it is proposed that nasopharyngeal angiofibroma is a testosterone dependent tumour A nidus of hamartomatous vascular tissue in [ INTRODUCTION: Juvenile Nasopharyngeal Angiofibroma (JNA) is a rare benign tumour that occurs almost only in adults and young male patients [1,2,3,4]. It represents 0.05 to 0.5% of all head and neck tumours [5,6]. Incidence in India and Egypt is slightly higher than in USA and Europe Nasopharyngeal carcinoma is difficult to detect early. That's probably because the nasopharynx isn't easy to examine and symptoms of nasopharyngeal carcinoma mimic those of other, more-common conditions. Treatment for nasopharyngeal carcinoma usually involves radiation therapy, chemotherapy or a combination of the two The management of juvenile nasopharyngeal angiofibroma has undergone a significant evolution, with more surgeons moving towards the minimal invasive endoscopic approaches. Although considered the standard of care by most, an endoscopic approach may not be sufficient for extensive tumours, as exemplified by the current case of a young man presenting with the largest juvenile nasopharyngeal.
