Infectious syphilis mimicking neoplastic disease

Area of Science:

• Infectious Diseases
• Oncology
• Dermatology

Background:

• Syphilis diagnosis can be challenging, sometimes mimicking other serious conditions like malignant neoplasm.
• Increasing incidence of sexually transmitted diseases necessitates improved diagnostic awareness.

Observation:

• Five patients evaluated for cancer were diagnosed with infectious syphilis (primary, secondary, or persistent primary).
• Two patients were candidates for radical surgery, and one for extensive radiation/chemotherapy.
• Elevated VDRL (Venereal Disease Research Laboratory) test results were key in diagnosing four patients.

Findings:

• Dark-field examination is critical for diagnosing primary syphilis.
• VDRL and FTA-ABS (fluorescent treponemal antibody absorption) tests are essential for confirming secondary syphilis.
• Penicillin remains the primary therapeutic agent for syphilis.

Implications:

• Misdiagnosis of syphilis as malignant neoplasm can lead to aggressive, unnecessary treatments.
• Enhanced educational programs for medical professionals are vital to address the rising rates of sexually transmitted diseases.
• Prompt and accurate diagnosis of syphilis is essential for appropriate patient management and outcomes.
