Malignant Syphilis in an Immunocompetent Adult Male

Area of Science:

• Dermatology
• Infectious Diseases
• Syphilology

Background:

• Malignant syphilis is an uncommon manifestation of syphilis, particularly in individuals with intact immune systems.
• It is characterized by severe, widespread skin lesions that can mimic other dermatological conditions.

Purpose of the Study:

• To report a rare case of malignant syphilis in an immunocompetent adult.
• To highlight the diagnostic features and successful treatment of this severe syphilis variant.

Main Methods:

• Clinical presentation of a 35-year-old immunocompetent male with noduloulcerative lesions.
• Diagnostic workup included examination of lesion morphology, serological tests for syphilis, and histopathology.
• Therapeutic intervention with penicillin and assessment of lesion response.

Main Results:

• The patient presented with extensive pustules, nodules, and ulcers on the trunk, face, and limbs.
• Serological tests and histopathology confirmed the diagnosis of syphilis.
• Lesions resolved completely after penicillin treatment.

Conclusions:

• Malignant syphilis can occur in immunocompetent individuals and presents with distinctive noduloulcerative lesions.
• A combination of characteristic morphology, serology, histopathology, and therapeutic response is crucial for diagnosis.
• Penicillin remains an effective treatment for malignant syphilis.
