Abstract: A three and a half-year-old boy suffered from reddish-brown macules and papules on his perianal and external genitalia skin for a month and worm-erosion alopecia for one week, with no conscious symptoms. Serological examination showed that treponema pallidum particle assay (TPPA) was positive, and the rapid plasma reagin test (RPR) titer was 1∶32. TPPA of his parents and grandparents was negative, while TPPA of his maternal grandparents was positive and RPR titers were 1∶16 and 1∶64, respectively. The child was diagnosed as acquired secondary syphilis.
