Plantar papillomatous lesions due to yaws infection

This image depicts the sole of a 9-year-old boy who exhibited plantar papillomatous lesions, which had been due to a yaws infection, also known as frambesia tropica, caused by the spirochete Treponema pallidum subspecies pertenue. The lesions were evident at the corners of his mouth and chin. The Venereal Disease Research Laboratory (VDRL) test produced a positive result of 1:128 and was accompanied by the fluorescent treponemal antibody absorption (FTA-ABS) and microhemagglutination assay (MHA-TP) tests, which were both reactive, or positive.
