The purpose of this article is to help prove that rhinopharyngitis mutilans, keratoma plantare sulcatum, and juxta-articular nodules are all tertiary lesions of Framboesia tropicum or “yaws.” For the sake of briefness and clearness, only a few of the most typical cases are described in this article.
Leys (1) in 1906, in Guam, described rhinopharyngitis mutilans for the first time as a destructive ulcerous rhinopharyngitis. Other investigators, Brien (2) and Howard (3), in describing this malady differ in their views only in the matter of the starting point of the ulcer; the ultimate result being the same. These two men together with Musgrave, Marshall (4) and many others are of the opinion, the cause is not syphilis, yet they do not associate it with yaws.
Rhinopharyngitis mutilans has often been confused with gangosa, which means “nasal voice.” Nearly all ulcerative processes destructive to the nasal cavity have been considered as gangosa.
