1C1D.0 Primary yaws
International Classification of Diseases for Mortality and Morbidity Statistics, 11th Revision, v2024-01
Primary yaws results from primary inoculation of Treponema pallidum subsp. pertenue into the skin, manifesting 2-12 weeks later as a localised papule (initial, primary or ‘mother' yaw) before developing into a large non-tender ulcerating nodule, often resembling a raspberry (hence the name ‘framboesia’). The primary lesion is most commonly located on the legs and ankles may also be found on the buttocks, arms, hands, and face. It usually heals after 3–6 months and is still present at the onset of the secondary stage in only a minority (9-15%).
