Pharyngeal mixed tumor
Introduction
Brief introduction of pharyngeal mixed tumor The pharyngeal mixed tumor originates from the epithelium of the small parotid gland. The reason why it is called mixed tumor is that the initial understanding of the structure of the tumor is unclear. It is mistaken for the origin of the two germ layer tissues. Glandular epithelium, so called parotid pleomorphic adenoma, because the mixed tumor has been used for a long time, it is still used, mixed tumors occur in the parotid gland, the submandibular gland is second, the crotch is the third, and the pharynx is not seen. Can be sent to any age. There are many unconscious symptoms in the early stage, or foreign body sensation, pharyngeal discomfort, or difficulty swallowing. The pronunciation is vague. In severe cases, it may have difficulty in breathing. The body is seen in the pharynx or soft palate and is round, hemispherical, and soft and hard. One. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: oropharyngeal adhesions
Cause
Pharyngeal mixed tumor etiology
Genetic (30%):
A tumor is essentially a genetic disease. Various environmental and genetic carcinogenic factors cause DNA damage in a synergistic or sequential manner, thereby activating proto-oncogenes and/or inactivating tumor suppressor genes, plus changes in apoptosis-regulating genes and/or DNA repair genes , in turn, causing abnormalities in expression levels, causing transformation of target cells. The transformed cells are mostly clonal hyperplasia, and after a long multi-stage evolution process, one of the clones is relatively unrestricted, and the additional mutation causes the tumor to occur.
Pathology (30%):
The pathology shows that the tumor has a complete capsule, the texture is hard, and a few are soft or sac. The cut surface is smooth grayish gray, grayish yellow, and often has a lobulated shape. The structure under the microscope is more complicated, mainly epithelial tissue, which is arranged in a mass or papillary shape. The interstitial is composed of connective tissue and has muscle, fat and cartilage-like tissue.
Prevention
Pharyngeal mixed tumor prevention
1. In prevention, pay attention to a reasonable diet, eat more fresh vegetables, fresh fruits. Eat more foods rich in vitamins, do not be too high in fat, eat some foods rich in cellulose.
2. In adjuvant therapy, the purpose of diet therapy is to enhance physical fitness, to make various treatments work properly, and to improve the body's immunity, so as to prevent metastasis and recurrence.
3. To avoid excessive emotional excitement, to maintain a comfortable mood, to ensure smooth circulation of blood and improve the body's disease resistance,
4. Encourage patients to get enough nutrients to eat high-protein, high-vitamin, high-calorie, digestible diets. For those with poor appetite and difficulty eating, it is advisable to have a small amount of meals, less slag diet, and intravenous high nutritional support if necessary.
Complication
Pharyngeal mixed tumor complications Complications oropharyngeal adhesions
Have a foreign body sensation, pharyngeal discomfort, or difficulty swallowing, pronounced vague, severe breathing may have difficulty breathing.
Symptom
Pharyngeal mixed tumor symptoms Common symptoms Dysphagia, Dysphagia, Pharyngeal foreign body sensation, Dyspnea
Pathology sees the tumor with multiple intact capsules, the texture is hard, a few are soft or sac sexy, the cut surface is smooth grayish gray, grayish yellow, often lobulated, the structure under the microscope is more complex, mainly epithelial tissue, in a mass Or papillary, the interstitial is composed of connective tissue, and has muscle, fat, cartilage-like tissue.
There are many unconscious symptoms in the early stage, or foreign body sensation, pharyngeal discomfort, or difficulty swallowing. The pronunciation is vague. In severe cases, it may have difficulty in breathing. The body is seen in the pharynx or soft palate and is round, hemispherical, and soft and hard. One.
Examine
Examination of pharyngeal mixed tumor
In the pharynx or soft palate, a round, hemispherical bulge is seen, and the touch is soft and hard. The diagnosis requires pathological examination. The pathology shows that the tumor is more intact, the texture is harder, and a few are soft or sac. The cut surface is smooth grayish gray, grayish yellow, and often has a lobulated shape. The structure under the microscope is more complicated, mainly epithelial tissue, which is arranged in a mass or papillary shape. The interstitial is composed of connective tissue and has muscle, fat and cartilage-like tissue.
Diagnosis
Diagnosis and diagnosis of pharyngeal mixed tumor
diagnosis
According to the symptoms and signs, the disease can be diagnosed, and the diagnosis requires pathological diagnosis.
Differential diagnosis
The disease should be differentiated from neurofibroma, adenocarcinoma, etc.
