Secondary framboesiform yaws.

Photo 1. Secondary framboesiform yaws. Thanks to a mass penicillin-based eradica- tion campaign, yaws is now a relatively rare disease in the humid tropics. This Papuan child shows classical framboesiform lesions, caused by Treponema pertenue. Secondary lesions are frequent also at muco-cutaneous junctions.

Plantar hyperkeratosis.

Photo 3. Gangosa. The most advanced and destructive lesions affect the maxillary bones and hard palate, resulting in a condition known as 'gangosa'.
