Tuberculous gumma is a form of tuberculosis that affects the skin, also known as cutaneous tuberculosis. It is a rare and less common form of tuberculosis, which is a bacterial infection caused by Mycobacterium tuberculosis.

Overview

Tuberculous gumma usually occurs in individuals who have a weak immune system or in those who have been previously infected with tuberculosis. The condition is characterized by the formation of a painless, firm, and smooth nodule that gradually enlarges and breaks down to form an ulcer.

Symptoms

The primary symptom of tuberculous gumma is the presence of a single or multiple nodules on the skin. These nodules are initially firm and painless, but they gradually enlarge and break down to form an ulcer. The ulcer is usually painless and has a smooth base with undermined edges.

Causes

Tuberculous gumma is caused by the bacterium Mycobacterium tuberculosis. The bacteria usually enter the body through the respiratory system, but they can also enter through the skin. The bacteria then spread through the bloodstream to various parts of the body, including the skin.

Diagnosis

The diagnosis of tuberculous gumma is usually made based on the clinical features and the results of laboratory tests. The tests may include a skin biopsy, bacterial culture, and polymerase chain reaction (PCR) test for Mycobacterium tuberculosis.

Treatment

The treatment of tuberculous gumma involves the use of antitubercular drugs. The drugs are usually given for a period of six to nine months. In some cases, surgical intervention may be required to remove the affected skin.
