ALMEIDA, Filipa Tavares; AZEVEDO, Filomena y LISBOA, Carmen. Syphilitic Balanitis of Follmann: Laboratory Pitfalls. Rev Soc Port Dermatol Venereol [online]. 2020, vol.78, n.3, pp.62-65. Epub 01-Sep-2021. ISSN 2182-2395. https://doi.org/10.29021/spdv.78.3.1199.
We report a case of early syphilis, presenting as balanitis and papular syphilides in an HIV-infected patient, with a previous history of syphilis infection, which demonstrated a false negative VDRL testing due to a prozone phenomenon. This false
negative response results from overwhelming antibody titers, which interfere with the proper formation of the antigen-antibody lattice network, necessary to visualize a positive flocculation test.
