SECONDARY SYPHILIS – CLINICOPATHOLOGICAL CORRELATION
Introduction: In recent years there has been a resurgence of syphilis. Infection by Treponema pallidum is mainly associated with inconsistent condom use and high number of sexual partners in the months preceding the diagnosis. Following the increase number of diagnosed cases, it is important to have a greater awareness of the clinical and pathological features of the disease. This article describes and correlates the clinical and histopathological features of secondary syphilis in 7 patients seen at the Department of Dermatology, Hospital Santa Maria, Lisbon, Portugal.
Material and Methods: Nine biopsies of mucocutaneous lesions from seven patients with secondary syphilis, observed between 2009 and 2013. The histopathologic and clinical findings were correlated and studied.
Results: This study revealed a broad spectrum of histopathological changes ranging from an inflammatory infiltrate of the superficial dermis with location to an extent perivascular in the deep dermis. Although there is some correlation between different patterns of inflammation and type of skin lesions, the macular lesions were associated with a superficial inflammatory infiltrate as papular, maculopapular , and nodular lesions were associated with a profound inflammatory process. The predominant infiltrate was plasmacytic. Neutrophils were observed only in the case of condylomata lata.
Conclusions: The histopathological features of secondary syphilis appear to be as varied as the clinical ones. It is the responsibility of the professionals who deal with these patients being particularly alert to the wide range of manifestations in this disease, remember this clinical diagnosis and be aware of the need for close interaction with dermatopathologists. The collaboration between pathologists and clinicians allows a correct correlation between clinical, serology and histopathological findings in order to establish a more plausibly diagnosis of syphilis.
