Swollen lymph nodes in the groin

Introduction Inguinal lymphadenopathy is very common, often suggesting lesions in tissues and organs around the lymph nodes. Therefore, inguinal lymphadenopathy usually indicates lesions in the reproductive system and peritoneal organs around the groin, including systemic diseases. Swelling at the groin or obturator, and touching the femoral head is one of the clinical diagnoses of anterior dislocation of the hip. Simple hip anterior dislocation is far less common in posterior dislocation.

Cause

Cause

First, chronic lymphadenitis

Most of them have obvious infections, and often have localized lymphadenopathy, pain and tenderness, generally no more than 2 to 3 cm in diameter, and will shrink after anti-inflammatory treatment. Inguinal lymphadenopathy, especially long-standing and unchanged flat lymph nodes, is of great significance.

Second, tuberculous lymphadenitis

Tuberculous lymphadenitis, in addition to inguinal lymphadenopathy, there are fever, sweating, fatigue, increased blood sedimentation and other symptoms, more common in young adults. Often accompanied by tuberculosis, the lymph nodes are uneven in texture, some are lighter (cheese-like), some are hard (fibrosis or calcification), and adhere to each other, and adhere to the skin, so the activity is poor. This type of patient is tuberculin test and blood tuberculosis antibody positive.

Third, malignant lymphoma

Malignant lymphoma can be seen in any age group, and its inguinal lymphadenopathy is often painless, progressive swelling, from large soybeans to jujube, medium hardness. Generally, it has no adhesion to the skin, and does not fuse with each other in the first and middle stages. In the later stage, the lymph nodes can grow to a large size, and can also be fused into a large piece, the diameter of which is more than 20cm, invading the skin, and it will not heal after rupture.

In addition, malignant lymphoma can invade the mediastinum, liver, spleen and other organs, including the lungs, digestive tract, bones, skin, breast, nervous system and so on. The diagnosis requires a biopsy.

Clinical manifestation

The normal lymph nodes of the human body are only the size of rice grains, soft, smooth and movable, without tenderness, and are generally difficult to reach. If the lymph nodes are swollen, painful, hardened, not smooth, adhere to the surrounding tissues, or become soft, touch the sense of wave, or even ulceration, etc., are "alarms" from lymph node lesions.

Differential diagnosis

Identification

1, chronic lymphadenitis: most of the obvious infection, and often localized lymphadenopathy, pain and tenderness, the general diameter does not exceed 2 ~ 3cm, will shrink after anti-inflammatory treatment. Inguinal lymphadenopathy, especially long-standing and unchanged flat lymph nodes, is of great significance.

2, tuberculous lymphadenitis: tuberculous lymphadenitis in addition to inguinal lymphadenopathy, there are fever, sweating, fatigue, increased blood sedimentation and other symptoms, more common in young adults. Often accompanied by tuberculosis, the lymph nodes are uneven in texture, some are lighter (cheese-like), some are hard (fibrosis or calcification), and adhere to each other, and adhere to the skin, so the activity is poor. This type of patient is tuberculin test and blood tuberculosis antibody positive.

3, malignant lymphoma: malignant lymphoma can be seen in any age group, its inguinal lymph node swelling is often painless, progressive swelling, from large soybeans to jujube, medium hardness. Generally, it has no adhesion to the skin, and does not fuse with each other in the first and middle stages. In the later stage, the lymph nodes can grow to a large size, and can also be fused into a large piece, the diameter of which is more than 20cm, invading the skin, and it will not heal after rupture.

In addition, malignant lymphoma can invade the mediastinum, liver, spleen and other organs, including the lungs, digestive tract, bones, skin, breast, nervous system and so on. The diagnosis requires a biopsy.

Clinically, malignant lymphoma is often misdiagnosed, with superficial lymph node enlargement as the first manifestation, 70% to 80% of patients diagnosed with lymphadenitis or lymph node tuberculosis at the time of initial diagnosis, resulting in delay in treatment.

4, the normal human lymph nodes are only the size of rice, soft, smooth and movable, no tenderness, generally not easy to touch. If the lymph nodes are swollen, painful, hardened, not smooth, adhere to the surrounding tissues, or become soft, touch the sense of wave, or even ulceration, etc., are "alarms" from lymph node lesions.
