Chronic lymphadenitis

Introduction to chronic lymphadenitis Chronic lymphadenitis is often secondary to inflammatory lesions in the head, face, and neck. Lymph nodes are swollen to varying degrees, scattered in the cervical region or submandibular and infraorbital regions. It can be slightly hard but has a smooth surface, can move, and can have mild tenderness or discomfort. Chronic lymphadenitis does not require treatment, and attention should be paid to the primary inflammation. In addition to the neck area, the scalp, outer ear and hidden parts such as the mouth, tonsils, and gums should be carefully examined. The primary lesion can also be found in the lymphatic recipient area of the enlarged lymph node. basic knowledge Sickness ratio: 0.1% Susceptible people: no special people Mode of infection: non-infectious Complications: cellulitis

Causes of chronic lymphadenitis

Various odontogenic infections, inflammation of the jaws, infections and ulcers of the oral mucosa, tonsillitis and pharyngitis, infections of the ears, nose, throat, eyes and parotid glands.

Chronic lymphadenitis prevention

Pay attention to personal hygiene, improve physical fitness, prevent various odontogenic infections, jaw inflammation, oral mucosal infections and ulcers, tonsillitis and pharyngitis, infections of the ear, nose, throat, eyes and skin parotid glands.

Chronic lymphadenitis complications Complications cellulitis

It can be further developed into glandular cellulitis.

Chronic lymphadenitis symptoms Common symptoms Oral mucosal ulcers pharyngitis, glossitis, phlegm and blood stasis

Local lymphadenopathy, initially in common sites, such as: submandibular, underarm, deep cervical lymph nodes, tenderness, peripheral clear, no adhesions, the disease continues to develop, lymph node inflammation spreads around the tissue, lymph node palpation is inactive, The pain is exacerbated and further developed into glandular cellulitis.

Chronic lymphadenitis has a history of repeated swelling, 2-3 lymph nodes, moderate hardness, activity, tenderness.

Chronic lymphadenitis check

1. The application of lymphatic angiography or isotope examination can help the differential diagnosis of lymphadenopathy.

2. Laboratory, blood routine see leukocytosis.

3. The sputum or sinus endocrine secretions can be detected by smear or concentration method to detect tubercle bacilli.

Diagnosis and diagnosis of chronic lymphadenitis

diagnosis

Diagnosis can be based on medical history, clinical symptoms, and laboratory tests.

Differential diagnosis

Tuberculous lymphadenitis

Have fever, sweating, fatigue, increased erythrocyte sedimentation rate, more common in young adults, often accompanied by tuberculosis, uneven lymph nodes, some lighter (cheese-like), some harder (fibrosis or calcification), They adhere to each other and adhere to the skin, so the activity is poor. These patients have tuberculin experiments and blood tuberculosis antibodies.

Malignant lymphoma

Can also be seen in any age group, its lymphadenopathy is often painless, progressive enlargement, from large soybeans to jujube, medium hardness, generally no adhesion to the skin, in the first and middle, do not merge with each other, can be active, At the end of the lymph node, the lymph nodes can grow to a large size, and can be fused into a large piece, the diameter of which is more than 20cm, invading the skin, and long-term unhealed after rupture. In addition, it can invade the mediastinum, liver, spleen and other organs, including the lungs and digestive tract. Bone, skin, breast, nervous system, etc., need to be confirmed by biopsy. Clinically, malignant lymphoma is often misdiagnosed. The first manifestation of superficial lymph node enlargement is 70%-80% diagnosed as lymph node at the time of initial diagnosis. Inflammation or lymph node tuberculosis, resulting in delay in treatment.

Giant lymph node hyperplasia

It is a rare disease that is easily misdiagnosed. It often manifests as unexplained lymphadenopathy, mainly invading the chest cavity, with the most mediastinum, and can also invade the hilar and lung. Other affected parts include the neck, retroperitoneum, pelvis, and armpit. And soft tissue, often misdiagnosed as thymoma, plasma cell tumor, malignant lymphoma, etc., understanding the pathology and clinical manifestations of this disease is extremely important for early diagnosis.

Pseudo lymphoma

Frequently occurring in the lymph nodes, such as the eyelids, pseudo-lymphoma of the stomach and lymphatic polyps of the digestive tract, can form a mass, which is generally considered to be a reactive hyperplasia caused by inflammation.

Lymph node metastasis

Lymph nodes are often hard and uneven in texture, and primary lesions can be found, rarely in systemic lymphadenopathy.
