Yaws

The name given by the Africans to the disease called Frambœsia. On the American coast it is termed pian and epian. [Hoblyn1855]

A disease, occurring in the Antilles and in Africa, characterized by yellowish or reddish tumors, of a contagious character, which, in shape and appearance, often resemble currants, strawberries, or raspberries. There are several varieties of this disease, variously known as framboesia, pian, verrugas, and crab-yaws. [CancerWEB]

The term "yaws" is thought to be of Caribbean origin. In the language of the Carib Indian people, "yaya" was the word for "a sore." The disease yaws may have come from Africa where the word "yaw" may have meant "a berry." Because the bumps of yaws look like berries, the disease is also called frambesia (or frambesia tropica) from the French "framboise," meaning "raspberry." Other names for yaws include granuloma tropicum polypapilloma tropicum, and thymiosis. [Medicinenet]
