Extra-pulmonary tuberculosis (EPTB) affects areas outside the lungs. It impacts the lymph nodes, pleura, and bones. Patients often experience varied symptoms, depending on the affected site. Lymph node TB causes swelling, while bone TB results in pain. Pleural TB leads to chest pain and breathing issues. EPTB diagnosis requires different tests, including biopsy and imaging. Doctors commonly use PCR tests for accurate results. Treatment involves a lengthy antibiotic course, similar to pulmonary TB. Prompt diagnosis and treatment prevent severe complications. EPTB is common in immunocompromised patients, including those with HIV. However, healthy individuals can also develop EPTB. Public health strategies focus on early detection and treatment adherence.

Effective management requires a multidisciplinary approach, combining medical and supportive care. Education and awareness campaigns play a crucial role in controlling EPTB. Moreover, ongoing research aims to improve diagnostic methods and treatments. Therefore, understanding EPTB is essential for better healthcare outcomes.
Types
Common extra-pulmonary tuberculosis (TB) sites include:
Lymphatic TB: Affects the lymph nodes, often presenting as painless swelling.
Pleural TB: Involves the pleura, causing pleuritis and pleural effusion.
Skeletal TB: Affects bones and joints, commonly the spine (Pott’s disease).
Genitourinary TB: Involves the kidneys, bladder, and genital organs.
Meningeal TB: Affects the meninges, leading to TB meningitis.
Abdominal TB: Involves the gastrointestinal tract, peritoneum, and abdominal organs.
Cutaneous TB: Affects the skin, presenting as various dermatological conditions.
Ocular TB: Involves the eyes, causing uveitis, choroiditis, or keratitis.
Note: Each type has distinct clinical features and requires targeted diagnostic and therapeutic approaches.
