Histopathological Patrern of Early Syphilis

Area of Science:

• Dermatopathology
• Infectious Diseases
• Syphilis Research

Background:

• Early syphilis diagnosis relies on clinical and histopathological findings.
• Histopathology of secondary syphilis can exhibit diverse presentations.
• Understanding these variations is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To describe the histopathological features of early syphilis, focusing on primary and secondary stages.
• To highlight the range of histopathological presentations in secondary syphilis.
• To compare classical findings with less common observations in syphilis.

Main Methods:

• Retrospective analysis of 36 untreated early syphilis cases (10 primary, 26 secondary).
• Histopathological examination of skin biopsies.
• Correlation of histopathological findings with clinical presentation.

Main Results:

• Primary syphilis showed classic features: ulceration, exocytosis, perivascular lymphocytic/plasmacytic infiltrate, and endothelial proliferation.
• Secondary syphilis displayed varied histopathology, including lichenoid infiltrate (3 cases), psoriasiform changes (1 case), and granulomatous reactions (3 cases).
• Vascular changes were absent or inconspicuous in a significant proportion of secondary syphilis cases (22.2% and 8.3%).

Conclusions:

• Histopathology of primary syphilis is typically characteristic.
• Secondary syphilis exhibits a spectrum of histopathological findings, some deviating from classical descriptions.
• Awareness of these diverse presentations is essential for dermatopathologists and clinicians managing syphilis.
