Pharyngeal papilloma
Introduction
Introduction to pharyngeal papilloma Papilloma is a common benign tumor of the pharynx, which may be related to viral infection. It is formed by papillary protrusions on the surface of the skin or mucosal epithelium and its connective tissue. The nipple is a round or oval epithelial mass with loose and vascular connective tissue in the center. Mostly squamous cell papilloma. Most patients have no symptoms, or found in the pharyngeal examination, a small number may have dry throat, itching, foreign body sensation, etc., the larger may have swallowing and respiratory discomfort or obstacles. The treatment is mainly based on surgery, and it is removed, clamped, cut off or removed by laser, electrocautery, and freezing under topical anesthesia according to the condition. Those located in the larynx can be removed under an indirect laryngoscope or a direct laryngoscope. The prognosis of this disease is good, but it can recur, especially in patients with multiple or with laryngeal papilloma. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: difficulty swallowing
Cause
Causes of pharyngeal papilloma
A benign tumor that is more common in the pharynx may be associated with a viral infection, which is formed by a papillary projection of the skin or mucosal epithelium and its underlying connective tissue to the surface.
Prevention
Pharyngeal papilloma prevention
The disease may be related to viral infections and should be actively prevented from viral infections.
Complication
Pharyngeal papilloma complications Complications, difficulty swallowing
A small number may have dry throat, itching, foreign body sensation, etc., the larger may have swallowing and respiratory discomfort or obstacles.
Symptom
Symptoms of pharyngeal papilloma Common symptoms Dysphagia, swallowing, difficulty swallowing
According to the location and special appearance of the tumor, the diagnosis is not difficult, and the diagnosis requires pathological examination.
Most patients have no symptoms, or found in the pharyngeal examination, a small number may have dry throat, itching, foreign body sensation, etc., the larger may have swallowing and respiratory discomfort or obstacles.
Most of the tumors occur in the zygomatic arch, tonsil, soft palate, uvula, followed by the back of the soft palate, the posterior pharyngeal wall, and the epiglottis. The papilloma has different shapes, red or grayish white, and is hard or soft. The tumor is small, pedunculated or pedunculated, single or multiple, sputum, cauliflower or granular, diffuse and multiple in children.
Examine
Examination of pharyngeal papilloma
Tissue biopsy can confirm the diagnosis.
Pathological examination showed that the squamous epithelium overgrowed to form the nipple without expanding to the deep tissue. There was a fibrous vascular center in the center of the nipple. The nipple surface was hyperkeratotic squamous epithelium, slightly basophilic cytoplasm, and nuclear chromatin. Rich, no change, basal cells are neatly arranged. There are very few malignant changes in papilloma in children, and there are changes in tumor cells.
Diagnosis
Diagnosis and diagnosis of pharyngeal papilloma
According to the location and special appearance of the tumor, the diagnosis is not difficult, and the diagnosis requires pathological examination.
Differential diagnosis
1. Pharyngeal fibroma also occurs in the tonsils, soft palate, around the zygomatic arch, etc., is a reddish or grayish white pedicle, more than a single hair. However, the surface of the tumor is smooth, hard, covered with normal mucosa, and the roots are wide. Pathological examination can confirm the diagnosis.
2. The tonsil polyps are pedicle-like, pink, smooth, elliptical, and can move up and down, soft and polyp.
3. Localized tonsil tumor-like hyperplasia The tonsils have pedicled tumor-like protrusions, which hang into the pharynx. The color is the same as that of the tonsils. There are also small nests. When the tonsils are inflamed, the tumors also have the same inflammation. There are pus around the pedicles. Sex secretions.
