ACQUIRED ORAL SYPHILIS: REPORT OF 2 CASES AND REVIEW OF THE LITERATURE

Acquired oral syphilis (AOS) is an infectious disease caused by the bacterium Treponema pallidum. Transmission occurs mainly by sexual contact with infectious lesions. Two cases of AOS have been reported. A 29-year-old male patient presented with grayish-white mucous patches and reddish ulcers in the lips, lateral border of the tongue, floor of the mouth, and the oropharynx. The patient was a marijuana user. A 33-year-old female patient presented with pruritus of the tongue and throat, pain in the upper labial mucosa for 1month, and halitosis. Reddish ulcers 5 mm in size were detected in the upper labial mucosa, posterior dorsal surface of the tongue, gingiva, and palate. A maculopapular cutaneous rash was also observed. The patients did not report systemic comorbidities. Venereal Disease Research Laboratory (VDRL) and fluorescent treponemal antibody absorption (FTA-ABS) were both positive, confirming the clinical diagnosis of syphilis. They patients were referred for adequate treatment and remission of the oral lesions was observed. Support: FAPEMIG.
