Primary rectal Syphilis mimicking rectal tumor.

Abstract

Introduction: Syphilis is a sexually transmitted disease with a raising incidence.

Case report: 18 year-old male with a inflammatory rectal pseudo-tumor. After diagnosis, antibiotic therapy was administered with uneventful recovery.

Discussion: Rectal syphilis is a rare condition, with particular endoscopic and imaging findings that allow differentiation from rectal malignancy. Direct visualization of Treponema Pallidum with  inmunohistochemistry staining confirms the diagnosis.

Conclusion: Syphilitic proctitis must be suspected among high-risk patients with atypical rectal tumors. Active management of sexual partners is crucial for early diagnosis and treatment.
