[Histopathological aspects of tertiary pinta].

Abstract

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.
