nasal glioma
Introduction
Introduction to nasal glioma Nasal glioma (nasalglioma) is a rare benign congenital tumor and is an atopic nerve tissue. The etiology is unknown, and the pathogenesis is still unclear. Clinically, the lesions are solid, smooth, and reddish blue to purplish red nodules. It can occur in the nasal cavity, or in both the nasal cavity and the inside, through the nasal bone of the defect. Clinically, it can occur in the midline of the bridge of the nose or the nose. The boundary of the tumor is clear, and it can be firm, smooth, reddish blue or purple, and resembles a hemangioma. basic knowledge The proportion of the disease: the incidence rate is about 0.001% -0.003% Susceptible people: no specific people Mode of infection: non-infectious Complications: overflowing tears
Cause
Cause of nasal glioma
(1) Causes of the disease
The cause is still unknown.
(two) pathogenesis
The pathogenesis is still unclear.
Prevention
Nasal glioma prevention
1. Adjust daily life and workload, and regularly carry out activities and exercise to avoid fatigue.
2. Maintain emotional stability and avoid emotional excitement and tension. 3. Keep the stool smooth, avoid using stools, eat more fruits and high-fiber foods. 4. Avoid cold irritation and keep warm.Complication
Nasal glioma complications Complications
Nasal gliomas have different growth sites, which lead to different clinical complications. They are located in the posterior part of the nose and can cause symptoms such as headache, vomiting and papilledema and increased symptoms of intracranial pressure and localized neurological damage. Occurred in the nasal bridge, can cause local bone destruction, resulting in a broken nose, causing obstruction of the nasolacrimal duct, leading to symptoms such as tears, if secondary bacterial infection, can cause rhinitis-like symptoms.
Symptom
Nasal glioma symptoms Common symptoms Increased intracranial pressure nodules
Skin lesions are firm, smooth, reddish blue to purple red nodules, 2 to 3 cm in diameter, shaped like hemangioma, occurring in the midline of the nose or nose, glioma can also occur in the nasal cavity, also It can be inside and outside the nasal cavity. They are connected through the missing nasal bone. X-ray filming should be performed to check the skull damage.
Examine
Nasal glioma examination
Currently there are no related content description.
X-ray film to check the skull damage, histopathology, composed of glial cells (astrocytes) and loose intercellular gelatin, glial cells are rather lightly colored, the nucleus is elliptical, neurons can Absent, but in some nasal gliomas, neurons are clearly focally present, neurons are triangular, nuclear deviation, cytoplasm rich, often containing Nissl particles, easy to identify.
Immunohistochemistry: Glial tissue was stained with glial fibrillary acidic protein, which showed a strong positive reaction. Neurons were positively stained with neuron-specific enolase, and axons responded positively to neurofilament antibodies.
Diagnosis
Diagnosis and diagnosis of nasal glioma
According to the clinical manifestations, the characteristics of skin lesions, histopathological features of immunohistochemical examination, X-ray film should be taken to check the skull damage, you can diagnose.
