In early lesions, treponemes may be demonstrated using silver stain.The World's Largest Public Domain Media Search Engine Biopsy of the lesions may reveal characteristic microscopic changes.Serological blood tests will be positive for syphilis.Dark field microscopy of swabs taken from early lesions may reveal treponemes.T carateum cannot be distinguished from other Treponema species that cause yaws and syphilis with commercially available laboratory tests.The diagnosis is commonly made based upon the appearance of the lesions.Tertiary pinta refers to late lesions, where the skin becomes achromic (with complete loss of pigment/colour) and atrophic (thin). Lesions may appear red, white, blue, violet, or brown. These are small papules and larger plaques called “pintids”, which occur after 6 months to 3 years, with abnormal pigmentation and scaling. Secondary pintaĭuring the second phase, a more widespread skin eruption may appear. Lymph nodes near affected skin may become enlarged, but the patient does not develop any systemic symptoms. The areas most commonly affected are exposed skin on the top of the feet, legs, back of the hands, and the forearms. It presents as one or more papules (small raised bumps) that slowly enlarge to become itchy, red, scaly plaques (large, flat lesiosn). Primary or early pinta occurs fter an incubation period of 2 to 3 weeks. Insect bites have been implicated in transmission, since they break the skin. Although the exact mode of transmission is unknown, pinta is probably transmitted by direct skin or mucous membrane contact. Pinta primarily affects children and young adults. The prevalence of pinta is decreasing in the 1950s about 1 million cases of pinta were reported, currently only a few hundred cases are reported per year. It was first described in the 16th century in Aztec and Caribbean Amerindians. Pinta is only found in scattered rural areas of Central and South America. Other species of Treponema are responsible for yaws and syphilis in humans, but unlike these conditions, pinta only affects the skin. Pinta, also called puru-puru or carate, is a relatively benign (mild and non- progressive) skin disease, caused by bacteria called Treponema carateum.
