Chin and neck following treatment for yaws

This image depicts a close view of the chin and neck of a 30-year-old woman who breastfed her 13-month-old infant and subsequently developed a lesion on her left breast, which was diagnosed as yaws. The infection spread to her back and chin. The Venereal Disease Research Laboratory (VDRL) test produced a positive result of 1:8 and was accompanied by the microhemagglutination assay (MHA-TP) test, which was also reactive, or positive. Treatment for this patient consisted of an intramuscular injection of 2.4 mega (million) units of benzathine benzylpenicillin. Note the marked improvement after only 1 week of antibiotic treatment.
