RESUMO
The nonvenereal treponematoses--yaws, endemic syphilis, and pinta--constitute a major health concern for many third world countries. These diseases are caused by an organism that is morphologically and antigenically identical to the causative agent of venereal syphilis, Treponema pallidum. Nonvenereal treponematoses differ significantly in their modes of transmission, epidemiology, and clinical presentation from venereal syphilis. Like venereal syphilis, they have a chronic relapsing course and have prominent cutaneous manifestations. Recently, several cases of imported yaws and endemic syphilis have been described in Europe. With the escalating U.S. military presence in many remote areas of the world and ever-increasing world-wide travel, the diagnosis of the nonvenereal treponematoses must be considered in appropriate clinical and historical situations.

A study was made of twenty-two biopsies of achromic lesions of Tikuna Indians, carriers of tertiary pinta, inhabitants of the Umariuassu island, on the Peruvian border, ten of the subjects had been treated two years previously with a single dose of penicillin. The histopathological picture was similar for both groups. In most cases (86.36%) slight hyperkeratosis was found on the epidermis, as well as acanthosis (18.18%), with atrophy in only two cases (9.09%). In all cases there was a reduction of the melanin of the basal layer. The inflammatory lymphocyte infiltrate was predominantly perivascular (88.18%). There wasn't any endothelial swelling.
