A67.2 Late lesions of pinta

Name of the Condition

• Late lesions of pinta

Summary

Late lesions of pinta represent the final stage of a chronic skin infection caused by Treponema carateum. These lesions are characterized by permanent skin changes, including discoloration, scarring, and textural alterations, primarily affecting exposed areas of the body. The condition progresses through distinct stages, with late lesions marking the end phase of the infection after initial and intermediate changes.

Causes

Late lesions of pinta result from infection with Treponema carateum, a spirochete bacterium. Transmission occurs through direct skin-to-skin contact with an infected individual, typically in environments with poor hygiene and limited access to healthcare. The bacterium invades the skin, leading to progressive changes that culminate in late-stage lesions.

Risk Factors

• Living in or traveling to endemic tropical regions (e.g., parts of Central and South America).
• Prolonged exposure to infected individuals without protective measures.
• Limited access to healthcare and hygiene resources.

Symptoms

• Permanent discoloration (hyperpigmentation or hypopigmentation).
• Scarring and textural alterations of the skin.
• Atrophy or thickening of affected areas.
• Loss of pigment in severe cases.

Diagnosis

Diagnosis is based on clinical presentation, including the characteristic late-stage skin lesions and history of exposure. Laboratory confirmation may involve serologic testing, though clinical evaluation remains primary. The progression from earlier stages (primary or intermediate) supports diagnosis.

Treatment Options

Treatment typically involves antibiotics, such as penicillin, to eliminate the bacterium. Topical therapies may address secondary symptoms like itching or scaling. Early intervention can prevent progression, but late lesions may require symptomatic management due to permanent changes.

Prognosis and Follow-Up

Prognosis is generally good with treatment, though late lesions may leave permanent skin changes. Follow-up ensures resolution of infection and monitors for complications. Regular skin examinations are recommended to assess healing and address residual effects.

Complications

• Permanent scarring or discoloration.
• Secondary bacterial infections from skin breakdown.
• Psychological impact due to visible skin changes.

Lifestyle & Prevention

• Avoid direct skin contact with infected individuals.
• Practice good hygiene, especially in endemic areas.
• Use protective clothing to minimize exposure in high-risk regions.

When to Seek Professional Help

Seek care if skin lesions persist, worsen, or show signs of infection (e.g., increased redness, pus). Early evaluation is important for managing progression and preventing complications.

Tips for Medical Coders

Document the presence of late-stage skin changes, including discoloration, scarring, or textural alterations, to support the A67.2 code. Include details on lesion location, progression from earlier stages, and any associated symptoms. Ensure clinical correlation with the chronic nature of pinta and exposure history.
