Disease description:

Recently, I developed oral ulcers, which have caused unbearable pain and significant discomfort. I noticed oval-shaped blisters in my mouth, and the doctor mentioned it might be an early-stage syphilitic ulcer. I would like to ask the doctor: what does an early-stage syphilitic oral ulcer look like?

The early oral ulcers of syphilis mainly present as chancroid-like ulcers, with the following characteristics: 1. Ulcer morphology: They typically appear as round or oval ulcers with clear boundaries, a relatively flat base, and may be covered with a layer of grayish-white membrane. 2. Texture and elasticity: The ulcer surface is relatively smooth, has some elasticity, and is not easily ruptured. 3. Location and distribution: These ulcers commonly occur on oral mucosa, such as the tongue and cheek areas, and sometimes may also appear on the inner side of the lips. 4. Accompanying symptoms: In addition to the ulcer itself, there may also be inflammatory reactions such as redness (erythema) and congestion of the oral mucosa, along with the presence of gum-like discharge. If related symptoms occur, it is recommended to seek timely medical consultation for professional examination and treatment to confirm diagnosis and control disease progression.
