Treponematosis in a 14th century skeleton from Wroclaw, Poland

ABSTRACT  At Saint Idzi`s Church in Wroclaw, Poland, ten 14th-15th century graves were discovered. Extensive defects in the bone were found on a preserved skeleton belonging to a male whose age was maturus. Macroscopic, histologic, X-ray, and TC examinations were conducted. The changes visible on the skull and lower limb bones are characteristic of syphilis.
