As part of a case-control study to investigate the high incidence of cervical cancer in Costa Rican women, the seroprevalence of the treponematoses, in particular, syphilis was determined. In each age group, women with a history of two or more sex partners were two to four times more likely to be seroreactive in tests for syphilis than women with zero or one sex partner. The highest percentage of reactive results in the microhemagglutination assay for antibodies to Treponema pallidum (MHA-TP) was seen in samples from women aged 50-59 who had had two or more lifetime partners (23.8%). Three observations from our study support reactivity due to syphilis rather than yaws or pinta: (1) a similar percent of reactive rapid plasma reagin (RPR) card test results among MHA-TP reactors in the two age groups of women who were surveyed (42 vs. 49%) was observed; (2) women who were seroreactive in the MHA-TP had multiple risk factors for STD [low socioeconomic status (9.4%), urban residence (22.8%), first intercourse under 16 years of age (14.1%), and multiple sex partners (26.3%)], and (3) only sexually experienced women had reactive results in the MHA-TP test.

We present a study of biopsies taken from skin lesions of 44 patients presenting with primary or secondary syphilis. In most primary lesions erosion or, more often, ulceration was present, with a dense inflammatory infiltrate. In secondary syphilis a wide variety of histological changes was present. Blood vessels were frequently involved, with marked endothelial swelling and often proliferation. Treponemes were demonstrated with the Steiner staining method in all investigated cases of primary syphilis and in 71% of secondary syphilis cases. Treponemes were present throughout the dermis, particularly perivascularly, and in the dermal-epidermal junction zone. In two specimens of secondary syphilis treponemes were located predominantly in the epidermis, but there were always some microorganisms demonstrable in the dermis. The inflammatory infiltrate was often located in a perivascular coat-sleeve-like arrangement. In this study plasma cells and lymphocytes were present in all specimens of primary and secondary syphilis. Syphilitic lesions differed from yaws lesions mostly in the location of treponemes and the affection of blood vessels. In this histopathological study of early syphilis, treponemes did not show the epidermiotropic character of yaws, and blood vessel changes were more pronounced than in yaws. Unfortunately, due to the protean histopathological manifestations described in venereal syphilis and in yaws, these two treponemal diseases cannot always be differentiated on histological grounds alone.

Yaws is a non-venereal endemic treponemal infection caused by Treponema pallidum sub-species pertenue, a spirochaete bacterium closely related to Treponema pallidum ssp. pallidum, the agent of venereal syphilis. Yaws is a chronic, relapsing disease predominantly affecting children living in certain tropical regions. It spreads by skin-to-skin contact and, like syphilis, occurs in distinct clinical stages. It causes lesions of the skin, mucous membranes and bones which, without treatment, can become chronic and destructive. Treponema pallidum ssp. pertenue, like its sexually-transmitted counterpart, is exquisitely sensitive to penicillin. Infection with yaws or syphilis results in reactive treponemal serology and there is no widely available test to distinguish between these infections. Thus, migration of people from yaws-endemic areas to developed countries may present clinicians with diagnostic dilemmas. We review the epidemiology, clinical presentation and treatment of yaws.
