Name of the Condition

• Acute lymphadenitis of trunk
• ICD-10 Code: L04.1

Summary

Acute lymphadenitis of the trunk is an inflammation of the lymph nodes in the trunk area, which includes the chest, back, and abdomen. This condition often results from an infection, leading to painful and swollen lymph nodes.

Causes

• Infections: The most common cause is a bacterial or viral infection, such as Streptococcus or Staphylococcus.
• Skin Infections: Dermatitis or a severe skin infection near the trunk area can spread to the lymph nodes.
• Immune Responses: The body's reaction to infection can cause lymph node inflammation.

Risk Factors

• Age: More common in children and young adults.
• Infection Exposure: Frequent exposure to infections or poor hygiene.
• Immunocompromised State: Individuals with weakened immune systems, such as those with HIV/AIDS, are at higher risk.

Symptoms

• Swelling and tenderness of the lymph nodes in the trunk area.
• Redness or warmth over the affected area.
• Fever, chills, or general discomfort.
• Fatigue and malaise.

Diagnosis

• Physical Examination: Palpation to check the size and tenderness of lymph nodes.
• Blood Tests: To determine the presence of an infection.
• Imaging Tests: Ultrasound or CT scans to assess the inflammation extent.
• Biopsy: In rare cases, to rule out other conditions like lymphoma.

Treatment Options

• Antibiotics: If a bacterial infection is present, antibiotics help eliminate the underlying infection.
• Pain Relief: NSAIDs or acetaminophen to manage pain and fever.
• Warm Compresses: Relieve tenderness and promote drainage.

• Surgery: Rarely, drainage of an abscess may be necessary if conservative treatments fail.

  Prognosis and Follow-Up

• Prognosis: Generally good with appropriate treatment; symptoms usually resolve in a few weeks.
• Follow-Up: Regular check-ups to ensure the infection is fully cleared and to manage any recurring infections.

Complications

• Abscess Formation: If untreated, the inflamed lymph nodes may become abscessed.
• Chronic Lymphadenitis: Persistent infection may lead to chronic swelling.

Lifestyle & Prevention

• Hygiene: Proper skin hygiene can help prevent skin infections.
• Timely Treatment: Early treatment of infections can prevent lymphadenitis.
• Healthy Lifestyle: A balanced diet and regular exercise support immune function.

When to Seek Professional Help

• Persistent fever or chills.
• Rapid increase in lymph node size.
• Severe pain not alleviated by over-the-counter medications.

Tips for Medical Coders

• Ensure specific code L04.1 is used for acute lymphadenitis of the trunk.
• Differentiate between acute and chronic lymphadenitis for proper coding.
• Verify the location (trunk) and nature (acute) of lymphadenitis to avoid misclassification.
