Tuberculosis (TB), when it manifests on the face as tuberculous chancre (primary inoculation TB), causes painless lesions (patches of raised, pale, and discolored skin).
How TB Affects the Face
- Initial Appearance: After exposure to TB, usually within two to four weeks, small bumps (papules) and nodules can appear on the face.
- Lesion Formation: These small bumps will join together to create larger areas of affected skin.
- Appearance of Lesions: These areas are described as raised, pale, and discolored patches.
- Pain: Notably, these lesions are generally painless.
Understanding Tuberculous Chancre
Tuberculous chancre, also called primary inoculation TB, is a specific type of tuberculosis that occurs at the site where the bacteria enters the body. In the context of the face, this typically happens due to direct contact with infected materials, such as skin-to-skin contact with an infected person.
Timeline and Location
| Feature | Description |
|---|---|
| Onset | Usually 2-4 weeks after exposure. |
| Initial Marks | Papules and nodules. |
| Lesion Type | Painless, raised, pale, and discolored skin patches. |
| Location | Can affect the face, arms, or legs. |
Important Note
It’s essential to note that TB affecting the face is not the most common form of tuberculosis. Most often, TB affects the lungs. Therefore, seeing a medical professional is crucial for accurate diagnosis and treatment.
