Pinta (disease)
Pinta (also known as Azul, Carate, Empeines, Lota, Mal del Pinto and Tina) is a human skin disease endemic to Mexico, Central America, and South America caused by infection with a spirochete, ''Treponema pallidum carateum'', which is morphologically and serologically indistinguishable from the organism that causes syphilis.〔(【引用サイトリンク】url=http://emedicine.medscape.com/article/225576-overview )〕
==Presentation==
Pinta, the least severe of treponemal infections being limited to the skin, is thought to be transmitted by skin-to-skin contact (similar to bejel and yaws), and after an incubation period of two to three weeks, produces a raised papule, which enlarges and becomes hyperkeratotic (scaly/flaky). Lesions are usually present in the exposed surface of arms and legs. Local lymph nodes might be enlarged. Three to 9 months later, further thickened and flat lesions (pintids) appear all over the body. These generally resolve, but a proportion of people with pinta will go on to develop late-stage disease, characterised by widespread pigmentary change with a mixture of hyperpigmentation and depigmentation which can be disfiguring.
