ICD-10: L03.0

ICD-10 code L03.0 specifically refers to cellulitis and acute lymphangitis of the finger and toe. This condition is characterized by an infection that affects the skin and subcutaneous tissues, often leading to inflammation and swelling. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

Cellulitis is a bacterial skin infection that typically manifests as a red, swollen area that feels warm and tender to the touch. It can occur anywhere on the body but is particularly common in the extremities, such as the fingers and toes. Acute lymphangitis, on the other hand, is an inflammation of the lymphatic vessels that can accompany cellulitis, often presenting with red streaks extending from the infected area towards the nearest lymph nodes.

Etiology

The most common causative organisms of cellulitis include Staphylococcus aureus and Streptococcus pyogenes. These bacteria can enter the skin through breaks, cuts, or abrasions, leading to infection. Risk factors for developing cellulitis include:

• Diabetes mellitus: Impaired immune response can increase susceptibility.
• Skin conditions: Eczema or athlete's foot can create openings for bacteria.
• Obesity: Increased skin folds can harbor bacteria.
• Immunocompromised states: Conditions that weaken the immune system heighten risk.

Symptoms

Patients with cellulitis and acute lymphangitis of the finger and toe may present with:

• Localized redness and swelling: The affected area appears inflamed.
• Pain and tenderness: Discomfort is often significant, especially when moving the affected digit.
• Warmth: The skin over the infected area feels warm to the touch.
• Fever and chills: Systemic symptoms may occur, indicating a more severe infection.
• Red streaks: These may be visible along the lymphatic vessels, indicating lymphangitis.

Diagnosis

Diagnosis is primarily clinical, based on the appearance of the skin and associated symptoms. In some cases, laboratory tests may be performed to identify the causative organism, especially if the infection is severe or recurrent. Blood cultures or wound cultures may be indicated if systemic symptoms are present.

Treatment

Treatment typically involves:

• Antibiotics: Empirical therapy is often initiated with broad-spectrum antibiotics, which may be adjusted based on culture results.
• Supportive care: Elevation of the affected limb and analgesics for pain management.
• Surgical intervention: In cases of abscess formation or if there is no improvement with antibiotics, incision and drainage may be necessary.
