Malignant tumor of ear
Introduction
Introduction to ear malignant tumors Malignant tumors are rare in the outer ear, and foreign statistics occur in the auricle and its adjacent structures of malignant tumors, accounting for about 6% of systemic skin malignancies. Friedmann (1974) counted 295 cases of ear malignant tumors, including 58 cases (19%) in the auricle, 158 (54%) in the external auditory canal, and 79 (72%) in the middle ear. The malignant tumor of the external ear occurred in the auricle or external auditory canal. Squamous cell carcinoma is the most common. Secondly, the auricle is basal cell carcinoma, the external auditory canal is adenoid cystic carcinoma, and other malignant tumors such as rhabdomyosarcoma, malignant melanoma are rare. This tumor is often misdiagnosed as otitis externa, otitis media, and external ear canal bone disease in the clinic. Therefore, for middle-aged and above patients, the painful mass of the external auditory canal with a long course of disease, especially the external auditory canal, has obvious ear pain in the early stage of the disease. Partial and no acute inflammation manifestations, especially should be vigilant, the final diagnosis depends on pathological examination. basic knowledge The proportion of illness: 0.002% Susceptible people: no special people Mode of infection: non-infectious Complications: otitis externa otitis
Cause
Causes of malignant tumors of the ear
The cause of squamous cell carcinoma: Auricular squamous cell carcinoma may be associated with ultraviolet radiation, such as exposure to intense sunlight, and external squamous cell carcinoma may be associated with inflammatory stimuli in chronic otitis externa or chronic otitis media.
Prevention
Ear malignant tumor prevention
Onions and garlic are excellent health foods. Eat 10 raw almonds a day, they contain a mauve-rich laetrile, or an anti-tumor agent. You can eat more sprouts, such as radish seedlings, bean sprouts, it is best to eat raw, or just a little hot with boiling water.
Complication
Ear malignant tumor complications Complications, otitis externa, otitis media
Squamous cell carcinoma of the external auditory canal is often invasive, can quickly invade the bone tissue underneath, and can involve the facial nerve.
External auricular adenoid cystic carcinoma can cause tinnitus, conductive hearing loss, and longer duration, which may be accompanied by secondary infection and ear leaks, such as otitis externa and otitis media.
Symptom
Symptoms of malignant tumors of the ear Common symptoms Intermittent ear pain, tinnitus, ear pain, maculopapular secondary infection, auricular pain, ear leak, auricle, radiation pain, ear discharge
1. Clinical manifestations of squamous cell carcinoma:
The early stage of auricular squamous cell carcinoma is a patchy maculopapular rash with itchiness. It tends to cause bleeding and gradually develop into an induration. After that, the surface is erosive, ulcerated or forms a cauliflower-like mass. There is no pain at the beginning, and pain in the late invasion of the perichondrium. More obvious, anterior ear canal squamous cell carcinoma is often diagnosed as chronic otitis externa or external auditory canal cholesteatoma. Patients often have bloody ear leaks. The skin of the external auditory canal is seen to be erosive, granulation tissue growth, tissue examination, often clear diagnosis, ear The development of squamous cell carcinoma is slow, and the metastasis is late. The most common site of metastasis is the parotid lymph node, followed by the jugular venous lymph node and the posterior lymph node. The external squamous cell carcinoma often infiltrates and can be quickly invaded. The bone tissue under it can affect the facial nerve.
2. Clinical manifestations of basal cell carcinoma:
From the beginning, it is often a gray nodule or a slightly raised skin hard spot. There is no discomfort, sometimes itchy sensation. It is easy to bleed after catching. The water is flowing and the induration gradually increases. The central ulcer forms an ulcer and the edge rises like a volcano. Oral, tumor invasive expansion, generally slow growth, basal cell carcinoma metastasis is rare, the main route of metastasis is local lymph node metastasis, but also distant metastasis, common parts of the lungs and bone.
Clinical manifestations of adenoid cystic carcinoma of the external auditory canal:
The external auditory canal adenoid cystic carcinoma grows very slowly. The medical history can be several years before the treatment. Intermittent ear pain often occurs in the early stage. It can be converted into persistent severe pain in the late stage, and spread to the ankle and ear circumference. The tumor is blocked. External auditory canal can cause tinnitus, conductive hearing loss, longer duration, may be associated with secondary infections and ear leaks, such as associated with external auditory canal, otitis media.
The local examination is mainly the cartilage of the external auditory canal, mostly located in the anterior and posterior wall of the external auditory canal. The base is wide, the texture is hard, it may be tender, the surface of the mass is intact (except when infected), it may be tender, and the tumor may be annular and hard. The external auditory canal is narrowed, and the tumor grows through the skin and has a red granule shape, and a purulent exudate is visible in the external auditory canal.
4. Clinical manifestations of melanoma:
More common in middle-aged and elderly, tumors often occur in the ear wheel, ear cavity, can also be seen in the external auditory canal and posterior region of the ear, early lesions are flat, smooth, gray-black pigmentation, late formation of masses, ulcers and necrosis, should pay attention to Yes, benign pigments in the ear, such as growth, burning, pain, or surface erosion, bleeding, should be highly alert to the possibility of malignant melanoma.
Examine
Examination of malignant tumors of the ear
Skull film, MRI examination of the nasopharynx, CT examination of the ear, nose and throat.
Diagnosis
Diagnosis and diagnosis of malignant tumors of the ear
diagnosis
This tumor is often misdiagnosed as otitis externa, otitis media, and external ear canal bone disease in the clinic. Therefore, for middle-aged and above patients, the painful mass of the external auditory canal with a long course of disease, especially the external auditory canal, has obvious ear pain in the early stage of the disease. Partial and no acute inflammation manifestations, especially should be vigilant, the final diagnosis depends on pathological examination.
Differential diagnosis
The disease is mainly differentiated from benign tumors of the ear, benign pigmented neurities of the ear, external auditory canal, otitis media, and external ear canal.
