Scrofuloderma is a type of cutaneous tuberculosis that is caused by the Mycobacterium tuberculosis complex. It is a form of tuberculosis that affects the skin, and is often associated with tuberculous lymphadenitis.

Causes

Scrofuloderma is caused by the Mycobacterium tuberculosis complex. This complex includes the bacteria that cause tuberculosis and Mycobacterium bovis, which is associated with tuberculosis in cattle. The bacteria can enter the body through the respiratory tract or through the skin.

Symptoms

The symptoms of scrofuloderma include skin lesions that are often painless and slow-growing. These lesions can be nodular, ulcerative, or both. They are often located on the neck, but can also occur on other parts of the body. Other symptoms can include fever, weight loss, and night sweats.

Diagnosis

The diagnosis of scrofuloderma is often made based on the clinical presentation and the patient's history. Laboratory tests, such as a skin biopsy or a tuberculin skin test, can also be used to confirm the diagnosis.

Treatment

The treatment for scrofuloderma typically involves a combination of antituberculous drugs. These drugs can include isoniazid, rifampin, pyrazinamide, and ethambutol. In some cases, surgery may be required to remove the affected lymph nodes.
