Nasal manifestations of yaws.

Yaws is an infectious, non-venereal disease of the tropical countries, which is caused by Treponema pertenue. Gangosa and goundou were seen commonly in cases of yaws in Africa, particularly in the early part of this century. After successful WHO mass treatment campaigns, these conditions are rarely seen now. A case of yaws with gangosa, goundou, and a nasopharyngeal carcinoma is presented here for its rarity.
