A51.32 Syphilitic alopecia

Name of the Condition

• Syphilitic alopecia

Summary

Syphilitic alopecia is a hair loss condition associated with secondary syphilis, caused by the bacterium Treponema pallidum. It typically occurs during the secondary stage of syphilis, which follows the primary stage and precedes tertiary syphilis. The hair loss may be patchy or diffuse and is often reversible with appropriate treatment.

Causes

Syphilitic alopecia is caused by Treponema pallidum, the bacterium responsible for syphilis. The infection spreads through direct contact with an infected sore during vaginal, anal, or oral sex. It can also be transmitted from mother to child during pregnancy or birth.

Risk Factors

• Unprotected sexual contact with an infected partner
• Having multiple sexual partners
• Previous history of sexually transmitted infections (STIs)
• Being in a sexual relationship with a partner who has syphilis

Symptoms

• Patchy or diffuse hair loss, often affecting the scalp, eyebrows, or eyelashes
• Hair loss may be accompanied by other symptoms of secondary syphilis, such as skin rashes, fever, or swollen lymph nodes
• Lesions or rashes on the scalp or other areas of the body

Diagnosis

Diagnosis involves blood tests to detect antibodies, such as the rapid plasma reagin (RPR) or Venereal Disease Research Laboratory (VDRL) test, followed by confirmatory tests like the fluorescent treponemal antibody absorption (FTA-ABS) test. Physical examination for characteristic hair loss patterns and other syphilis symptoms may also be performed.

Treatment Options

• Antibiotic therapy, primarily with penicillin, which cures the syphilis infection and typically resolves the hair loss
• For those allergic to penicillin, alternative antibiotics may be used under medical supervision

Prognosis and Follow-Up

With prompt and appropriate treatment, syphilitic alopecia usually resolves, and hair regrowth occurs. Follow-up testing is recommended to ensure the infection is cleared and to monitor for recurrence or progression to later stages of syphilis.

Complications

• Persistent hair loss if left untreated
• Progression to tertiary syphilis, which can affect the heart, brain, and other organs
• Increased risk of transmitting the infection to others

Lifestyle & Prevention

• Practice safe sex by using condoms consistently and correctly
• Limit the number of sexual partners and ensure regular STI screening
• Avoid sharing personal items that may come into contact with infected sores
• Pregnant individuals should undergo syphilis screening to prevent congenital transmission

When to Seek Professional Help

Seek medical attention if you experience unexplained hair loss, especially if accompanied by rashes, sores, or other symptoms of syphilis. Early diagnosis and treatment are crucial to prevent complications and transmission.

Tips for Medical Coders

When coding for syphilitic alopecia, use ICD-10-CM code A51.32. Ensure documentation supports the diagnosis, including clinical findings of hair loss associated with secondary syphilis and confirmation of the underlying infection. Note any relevant treatment or follow-up details to support accurate coding and billing.
