Synopsis

Pinta, also known as azul, carate, and mal de pinto, is a nonvenereal endemic treponemal infection caused by the spirochete Treponema pallidum ssp. carateum. The disease is confined to rural areas of northern South America and Mexico. However, current prevalence data is lacking.

Pinta is considered primarily a disease of children and adults, and most cases are limited to the skin. Infection usually is spread by person-to-person contact in endemic areas by direct skin or mucous membrane contact.

After an incubation period of 15-30 days, the primary infection begins as one or several small papules, usually on the exposed surfaces of the extremities, which enlarge over the course of 3-9 months. Regional lymph nodes may be enlarged and painless.

During this period, the color of the lesions changes from copper to slate blue. These lesions, or "pintids," are psoriasiform plaques and are painless but pruritic. Later the lesions can become hyper-, hypo-, and/or depigmented, thus giving pinta its name.

The late findings of pinta are limited to the skin. Regional lymphadenopathy is not uncommon. Leucoderma is the main complication, resulting in social stigma.
