How rare is juvenile nasopharyngeal angiofibroma?
How common is nasopharyngeal angiofibroma? Nasopharyngeal angiofibroma is very rare. It accounts for 1/5000 to 1/50,000 head and neck tumors.
What is Juvenile nasal angiofibroma?
Juvenile nasopharyngeal angiofibroma (JNA) is a benign vascular tumor that appears in the nasal cavity. Although it is non-malignant (not cancerous), it can expand quickly and extensively.
How do you diagnose Angiofibroma?
Tests for diagnosing angiofibroma An MRI or CT scan of the head and facial bones confirms the clinical diagnosis of angiofibroma and shows the extension of the tumor.
Why is Angiofibroma contraindicated in a biopsy?
Biopsy should be avoided as to avoid extensive bleeding since the tumor is composed of blood vessels without a muscular coat. Antral sign or Holman-Miller sign (forward bowing of posterior wall of maxilla) is pathognomic of angiofibroma.
Is juvenile nasopharyngeal angiofibroma?
Juvenile nasopharyngeal angiofibroma (JNA) is a rare benign tumor arising predominantly in the nasopharynx of adolescent males. It is an aggressive neoplasm and shows a propensity for destructive local spread often extending to the base of the skull and into the cranium.
How is Angiofibroma removed?
Angiofibromas can be safely & effectively removed by shave excision or electrosurgery, and less commonly using liquid nitrogen. Do not attempt self-removal of angiofibromas as that can often lead to permanent scars.
What is the cause of Angiofibroma?
What causes angiofibromas? Angiofibromas are caused by a local overgrowth of collagen, fibroblasts, and blood vessels. In tuberous sclerosis, mutations are present in tuberous sclerosis complex 1 (TSC1), which encodes the protein hamartin, and tuberous sclerosis complex 2 (TSC2) which encodes the protein tuberin.
What causes fibrous papule?
Why do fibrous papules occur? Fibrous papules are benign (non-cancerous) growths of the skin that occur with ageing. An individual usually only has one lesion, or sometimes two. When examined under the microscope, fibrous papules contain collagen and blood vessels.
Is Angiofibroma cancerous?
A benign (not cancer) tumor that is made up of blood vessels and fibrous (connective) tissue. Angiofibromas usually appear as small, red bumps on the face, especially on the nose and cheeks.

Can I cut off a fibrous papule?
A fibrous papules can be scraped off or cauterised.
What kind of tumor is a juvenile angiofibroma?
Juvenile Nasopharyngeal Angiofibroma is a rare tumor occurring almost exclusively in young males. Though the tumor is considered benign, it has a propensity for local invasion and destruction. It is classically described as invading “through natural fissures and foramina”.
When do juvenile nasopharyngeal angiofibromas usually occur?
Epidemiology. Juvenile nasopharyngeal angiofibromas occur almost exclusively in males and usually in adolescence (~15 years). They account for only 0.5% of all head and neck tumors 2, but are the most common of the benign nasopharyngeal neoplasms.
How old is the average person when they get angiofibroma?
It occurs almost exclusively in adolescent males, with an average age at diagnosis of 15 years old. The internal maxillary artery is the most common vascular source, other vessels include the ascending pharyngeal artery and external, internal, and common carotid arteries.
Which is the best treatment for angiofibroma?
Surgical resection (either open or increasingly endoscopic) is the treatment of choice, usually performed after pre-operative embolization to help with hemostasis. The embolization may be performed up to five days before. Irradiation may be an option if surgery is not possible or only incomplete resection achieved 2,4,6.
