Syphilis related to atypical oral lesions affecting an elderly man. a case report

ObjectiveTo present a case of oral syphilis in an old patient. BackgroundSyphilis seems to be resurging mainly in the young. However, in the last twenty years, the elderly have become more susceptive to infectious diseases due to a more frequent use of sildenafil. Clinical ReportAn 83-year-old man was referred to our clinic complaining of burning mouth. His medical history revealed papular lesions on chest and penis glans, which had been diagnosed and treated as scabiosis 2months prior to our assessment. The intra-oral examination showed erosive and patch lesions on the bilateral lip commissures, the palate and the border of the tongue. Initially, oral herpes was suspected. However, both the serological test and the cytology were negative. Therefore, syphilis was hypothesised. Non-treponemic (VDRL) and treponemic tests (FTA-ABS) were reagent and secondary syphilis was confirmed. The treatment consisted of penicillin G benzathine 2.4 million IU/IM for 4weeks. Both oral and skin lesions had complete remission. ConclusionThe present case illustrates that syphilis should be suspected in old patients with oral atypical lesions.
