salivary gland tuberculosis
Introduction
Introduction to parotid tuberculosis Tuberculosis of salivary gland (tuberculosis of salivary gland) is a rare parotid gland infection caused by the invasion of the parotid gland in the oropharynx and the lymphatic drainage caused by lymphatic drainage in the oropharynx. In 1893, Depaoli first reported parotid tuberculosis, and cases were reported in the future. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious complication:
Cause
Parotid tuberculosis
Mycobacterium tuberculosis infection can be primary infection, or secondary infection. The infection route is usually the skin of the head and face, the oropharynx, especially the tubercle of the tonsil area, infected by lymphatic drainage, blood infection, such as occurs Miliary tuberculosis can not be completely excluded, catheter retrograde infection is extremely rare, Bukchon reported a case of parotid duct tuberculosis, may be due to low salivary secretion, active tuberculosis in the lungs caused by tuberculosis, but some people think that blood can not be ruled out As a result, a small number of cases have a history of tuberculosis or a history of family tuberculosis.
Prevention
Parotid tuberculosis prevention
prevention
Pay attention to avoid contact with tuberculosis patients. If you have tuberculosis in other parts, you should use drugs to curb the spread of tuberculosis.
Prognosis
The prognosis is good as long as it is properly treated.
Complication
Parotid tuberculosis complications Complication
The most common complication of this disease is tuberculosis of the submandibular gland, sometimes manifested as a slight reduction in the process of gradual enlargement; acute inflammation may also occur as diffuse glandular tissue involvement, redness and even fluctuations.
Symptom
Parotid tuberculosis symptoms common symptoms parotid painless mass
Any age can occur, mostly between 20 and 30 years old, accounting for 60% to 70%, there is no significant difference in gender, the length of the disease varies, the short one for one month, the elderly for several years, can occur in the parotid essence Lymph nodes in the parotid gland can also occur. The latter are often misdiagnosed as tumors and treated as tumors. The most common of the three pairs of large parotid glands is the parotid gland (lymph node) tuberculosis. The primary infection appears in the parotid gland, and the infection may be From the tonsils or oral cavity, the common parotid tuberculosis is unilateral involvement, and may involve both sides. The common site is in front of the tragus and below the anterior humerus. The sternocleidomastoid muscle is located behind the parotid gland at the leading edge of the mastoid attachment. Extremely, the clinical manifestation is a painless mass. The percussion may be hard or soft, or even fluctuating (there is a cheese-like change or a suppurative infection), the mass is swollen, the boundary is generally clear, and pain may occur later, submandibular lymphatic tuberculosis Very common, sometimes involving the submandibular gland, causing tuberculosis in the submandibular gland, the patient's self-conscious symptoms are slowly growing tumors, but sometimes manifested as a slight reduction in the process of increasing; may also have acute inflammation Involved in diffuse glandular tissue, redness and swelling, and even fluctuations.
Examine
Check of parotid tuberculosis
An OT skin test, a needle biopsy or inoculation of a puncture into a mouse is valuable for diagnosis.
Parotid angiography, such as lesions confined to the lymph nodes, just like benign tumors, catheter displacement and space-occupying lesions; if the lesion destroys the capsule involving the glandular parenchyma, the catheter is interrupted, and the iodized oil pool appears as a malignant tumor. Therefore, Correct diagnosis before surgery is very difficult. The diagnosis is only by histopathological examination. The pus culture is sometimes cultivated with tuberculosis.
Diagnosis
Diagnosis and differentiation of parotid tuberculosis
Pay attention to the identification of tumors. When the parotid gland is angiographic, there is an iodized oil pool and it looks like a malignant tumor. Therefore, the diagnosis is only by histopathological examination, and the pus culture is sometimes cultivated.
1 In addition to the general symptoms of inflammation, there is swelling of the gland, pain, increased diet, congestion of the catheter mouth, swelling, pus discharge, severe inflammation spread into cellulitis.
2 Chronic inflammation also has glandular enlargement, no acute inflammation symptoms, submandibular gland inflammation can often touch the stone in the mouth and jaw. The mumps catheter discharges viscous saliva or dilute pus.
3 The parotid gland and submandibular gland radiographs showed ductal sausage-like destruction and acinar-like snowflake or cotton-like damage.
4 Acute mumps should be differentiated from mumps, cellulitis, and cellulitis.
5 Chronic mumps with glandular enlargement should be distinguished from parotid hypertrophy.
