lupus vulgaris

Lupus vulgaris is a form of cutaneous tuberculosis caused by Mycobacterium tuberculosis infection of the skin. Despite its name, it is not related to autoimmune lupus diseases such as systemic lupus erythematosus. The condition usually develops in individuals with previous tuberculosis exposure and a moderate immune response to the bacteria. It typically causes persistent reddish-brown skin patches or nodules that slowly enlarge over time and may lead to ulceration, scarring, or tissue damage if untreated. Commonly affected areas include the face, ears, and neck. Diagnosis may involve clinical examination, skin biopsy, microbiological tests, and tuberculosis testing. Treatment involves standard anti-tuberculosis medications.

Lupus vulgaris is not the same as autoimmune lupus. It is a long-lasting skin infection caused by tuberculosis bacteria. It can cause slowly growing skin patches or sores and is treated with tuberculosis medicines.
