EXTRAGENITAL chancres may be found on any portion of the body, and a case is being reported to further support this statement.
The standard textbooks on syphilis, as well as the available literature, have been carefully searched, and no mention is made of a primary chancre of the ear.

The case herein presented illustrates the important reality that any unusual lesion can be due to syphilis. This is often overlooked and is probably one of the reasons for the many unexplained positive Wassermann reactions found in routine examinations. With the advent of penicillin it is certainly more important now than it was before to diagnose and treat these lesions as quickly as possible. Every day lost results in
