I felt a small lump in the clavicle

If you feel small bumps inside the clavicle, it may be lymph node inflammation caused by the mass. Sometimes it is painless and itchy, but as the condition continues to worsen, it will cause complications. You need to go to the hospital to check out the cause, because there are many factors that cause lymph node inflammation, some are chronic and some are acute, depending on the individual's physical condition.

Common causes

Chronic lymphadenitis

Most of them have obvious infection foci, and often localized lymph node enlargement, pain and tenderness. The diameter usually does not exceed 2 to 3 cm, and will shrink after anti-inflammatory treatment. Inguinal lymphadenopathy, especially long-standing, unchanged, flat lymphadenopathy, is usually of no significance. However, unexplained enlargement of the cervical and supraclavicular lymph nodes indicates a systemic lymphoproliferative disease and should be taken seriously and further examined and confirmed.

Tuberculous lymphadenitis

Symptoms include fever, sweating, fatigue, and increased erythrocyte sedimentation rate, which are more common in young and middle-aged people. It is often accompanied by pulmonary tuberculosis. The texture of the lymph nodes is uneven, some parts are lighter (caseous change), some parts are harder (fibrosis or calcification), and they are adhered to each other and the skin, so their mobility is poor. These patients have positive tuberculin tests and blood tuberculosis antibodies.

Malignant lymphoma

It can also be seen in any age group. The lymph node enlargement is often painless and progressive, ranging in size from soybean to jujube, and of medium hardness. Generally, there is no adhesion to the skin, and they do not fuse with each other in the early and middle stages, so they are movable. In the later stages, the lymph nodes may grow very large or fuse into large masses with a diameter of more than 20 cm, invading the skin and taking a long time to heal after rupturing. In addition, it can invade the mediastinum, liver, spleen and other organs, including the lungs, digestive tract, bones, skin, breast, nervous system, etc. Diagnosis requires biopsy. Clinically, malignant lymphoma is often misdiagnosed. Among patients with superficial lymphadenopathy as the first symptom, 70% to 80% are diagnosed as lymphadenitis or lymphadenopathy tuberculosis at the initial visit, resulting in delayed treatment.

Giant lymph node hyperplasia

It is a rare disease that is easily misdiagnosed. It often manifests as unexplained lymphadenopathy, which mainly invades the chest cavity, most commonly the mediastinum, but can also invade the hilum and lungs. Other sites of involvement include the neck, retroperitoneum, pelvis, axilla, and soft tissue. It is often misdiagnosed as thymoma, plasmacytoma, malignant lymphoma, etc. Understanding the pathology and clinical manifestations of this disease is extremely important for early diagnosis.

Pseudolymphoma

It often occurs in areas outside the lymph nodes, such as pseudolymphoma of the eye sockets and stomach and lymphatic polyps of the digestive tract, all of which can form lumps. It is generally considered to be a reactive hyperplasia caused by inflammation.
