The term "simple chancre" may seem oddly spelled at first, but it actually follows the rules of English phonetics. In IPA transcription, the word is pronounced /ˈsɪmpəl ˈʃæŋkər/. The "i" in "simple" sounds like "ih" instead of "ee," while the "a" in "chancre" sounds like "æ" instead of "ay." The spelling of "chancre" is borrowed from French, while "simple" is a common English word, resulting in this unique combination of sounds. "Simple chancre" is a term used to describe a lesion associated with syphilis.
A simple chancre, also known as a primary syphilis sore or a hard ulcer, is a characteristic manifestation of the initial stage of syphilis infection. It is a painless, circular, firm, and usually solitary sore that forms at the site of entry of the spirochete bacteria, Treponema pallidum. The lesion typically develops on the genitals, anus, or mouth, but can occur anywhere on the body following sexual contact with an infected individual.
The simple chancre usually appears within three weeks of exposure to the bacteria, although the incubation period may range from 10 to 90 days. It begins as a small papule, which later develops into a larger ulcer with a clean base and indurated (hardened) edges. The sore is smooth and may be covered by a crust or scab. The chancre is highly contagious during this stage, and the bacteria can easily be transmitted through direct contact.
If left untreated, the simple chancre will spontaneously heal within four to six weeks, but this does not signify the end of the syphilis infection. Instead, the bacteria enter the bloodstream and spread throughout the body, progressing to the secondary stage of the disease. Therefore, it is crucial to seek medical attention as soon as a simple chancre is detected, in order to prevent the further complications and systemic involvement associated with syphilis.
In conclusion, a simple chancre is the characteristic skin lesion observed during the primary stage of syphilis infection, acting as a primary indicator for the need of medical evaluation.

The word "simple" in the term "simple chancre" refers to the concept of something being uncomplicated or straightforward. The word "chancre" originates from the Latin word "cancer", meaning "crab". In ancient medical terminology, this term was used to describe ulcers or erosions on the skin or mucous membranes. Over time, in the context of sexually transmitted infections, "chancre" specifically came to refer to the primary lesion caused by syphilis. The adjective "simple" distinguishes a basic or primary chancre from a more complex or secondary manifestation of syphilis.
