Cold abscess

Cold abscess is a type of abscess that is not accompanied by the usual signs of inflammation, such as heat, redness, and pain. It is often associated with conditions such as tuberculosis and actinomycosis.

Causes

Cold abscesses are typically caused by slow-growing bacteria, such as Mycobacterium tuberculosis and Actinomyces species. These bacteria can cause chronic infections that lead to the formation of abscesses without the typical signs of inflammation.

Symptoms

The main symptom of a cold abscess is a painless, slowly growing lump. The skin over the lump may be normal or slightly blue. The lump may feel soft or firm to the touch. Other symptoms can include weight loss, fatigue, and night sweats, which are common in conditions such as tuberculosis and actinomycosis.

Diagnosis

Diagnosis of a cold abscess can be challenging because the symptoms are often nonspecific. The diagnosis is usually confirmed by taking a sample of the abscess and examining it under a microscope or sending it to a lab for culture. Imaging tests such as ultrasound, CT scan, or MRI may also be used to help diagnose a cold abscess.

Treatment

Treatment of a cold abscess usually involves draining the abscess and treating the underlying infection with antibiotics. In some cases, surgery may be needed to remove the abscess.
