Syphilis should be considered as a differential diagnosis in patient with deep bony pain that worsens at night. We report a case of secondary syphilis presented with multiple bony swelling of both tibiae (sabre-like) and other long bones.展开更多

Methods: Different skin injury tissues of secondary syphilispatients, whose serum RPR and TPHA tests in the lab bothappeared positive reaction, were observed throughtransmission electron microscope(TEM). Results: Inflammations appeared on epidermides and coria,a great deal of neutrocytes, lymphocytes and a small amountof plasma innltrated them. Karyopyknosis, karyorrhexis,epicyte lysis and mitochondrion vacular degenerationoccurred. Spirocheta pallida was distributed on intercellularsubstances, epicytes and collagenous fibers. The epicytes werepressed to foveation. Conclusion The pathological change ofcharacteristic tissue ultrastructure reported here is ahistomorphological foundation to study the organism injurymechanism caused by syphilis.展开更多

The etiological agent consists of an anaerobic spirochete bacterium, Treponema pallidum. Laboratory diagnosis can be made through a direct investigation of the etiologic agent or non-treponemal (VDRL) and treponemal (FTA-Abs) serological tests. False-negative results are rare. Objectives: The present report presents a rare case of a man with a secondary syphilis syndrome who was initially undiagnosed due to the prozone effect, since he presented VDRL in low titers, and was later confirmed with a new diluted serum sample and VDRL and FTA-Abs, which were positive. Conclusion: A close look should be given to patients who, although the clinical condition is compatible, complementary exams may not be, and clinical cases should be carefully evaluated so that the patient is not treated late.展开更多
