Pharyngeal teratoma
Introduction
Introduction to pharyngeal teratoma Teratoma is a tumor that originates from the embryonic multi-embryonic tissue. It is rare in the pharynx and is mostly located in the nasopharynx. More women than men are benign tumors. Small deformity of the pharynx is often asymptomatic and missed. Sometimes it is found in the pharyngeal examination that a slightly larger tumor can partially block the pharynx and cause snoring, sucking discontinuity, more nasal secretions, heavy nasal sounds, itchy throat, nausea. Vomiting, etc., most tumors have pedicles, such as larger tumors perpendicular to the hypopharynx, suffocation in the vestibular larynx; difficulty in swallowing in the esophagus; obstruction of the nasopharyngeal mouth breathing, difficulty in feeding children. Physical examination showed that the tumor was pedicled, active, and resembled a polyp. It was blocky. The base of the pedicle was mucosa. The surface of the tumor was grayish or translucent, with numerous yellow cilia or hair. basic knowledge The proportion of illness: 0.0002%-0.0003% Susceptible population: more women than men Mode of infection: non-infectious Complications: difficulty swallowing
Cause
Causes of pharyngeal teratoma
The cause is unknown, it may be a true tumor originating from multi-embryonic tissue. Some people think that some cells in the embryo are separated from the overall effect, which is formed by disorderly differentiation and over-reproduction. The teratoma has complex tissue components, at least from two. The organization, classification and naming of germ layers are confusing.
Dermatomas or dermoid cysts (30%):
This type is more common, from the outer, mesoderm, the surface of the tumor is the skin, including sebaceous glands, sweat glands, hair, hair follicles, etc. The matrix is mainly adipose tissue, muscle, cartilage, bone, teeth, nerve and brain tissue, etc. The arrangement is disordered and does not form a complete organ.
Teratoma and true teratoma (30%):
From the three embryonic layers, including the endodermal stem and digestive tract epithelium, the former is poorly differentiated, does not have organ-like tissue, the latter is well differentiated, with organ-like tissue structure, patients can be associated with congenital malformations of the skull.
Maxillary parasitic (30%):
It is a highly differentiated teratoma with mature organs and limbs that are in the same hypocotyl direction as the host and are identifiable to the naked eye.
Prevention
Pharyngeal teratoma prevention
There are no effective preventive measures for tumors originating from embryonic multi-embryonic tissue. Early detection and early treatment are the key.
Complication
Pharyngeal teratoma complications Complications, difficulty swallowing
Most tumors have pedicles, such as larger tumors perpendicular to the hypopharynx, suffocation in the vestibular larynx; dysphagia in the esophagus; obstruction of the nasopharyngeal mouth, difficulty in feeding.
Symptom
Symptoms of pharyngeal teratoma Common symptoms Dysphagia, snoring, breathing, nausea, polyp cysts, asphyxia
Small deformity of the pharynx is often asymptomatic and missed. Sometimes it is found in the pharyngeal examination that a slightly larger tumor can partially block the pharynx and cause snoring, sucking discontinuity, more nasal secretions, heavy nasal sounds, itchy throat, nausea. Vomiting, etc., most tumors have pedicles, such as larger tumors perpendicular to the hypopharynx, suffocation in the vestibular larynx; difficulty in swallowing in the esophagus; obstruction of the nasopharyngeal mouth breathing, difficulty in feeding children.
Physical examination showed that the tumor was pedicled, active, and resembled a polyp. It was blocky. The base of the pedicle was mucosa. The surface of the tumor was grayish or translucent, with numerous yellow cilia or hair.
Examine
Inspection of pharyngeal teratoma
Feasible nasopharyngeal palpation, skull base X-ray, CT and other examinations are helpful for diagnosis and diagnosis based on pathological results.
Diagnosis
Diagnosis and diagnosis of pharyngeal teratoma
diagnosis
Larger tumors are easy to diagnose, small tumors and those located in the nasopharynx are more difficult to diagnose, feasible nasopharyngeal palpation, skull base X-ray, CT and other examinations are helpful for diagnosis, and the diagnosis is based on pathological results.
Differential diagnosis
Different from other types of tumors in the pharynx, pathological examination can be identified.
