Primary Rifampicin Mono-Resistant Extrapulmonary Tuberculosis Presenting as a Posterior Chest Wall Abscess: The World’s First Case

Extrapulmonary tuberculosis is a relatively infrequent occurrence. Tubercular involvement of the chest wall is rare. There has never been a record of an isolated primary rifampicin mono-resistant extrapulmonary tuberculosis presenting as a posterior chest wall abscess in the medical literature, making such cases extremely uncommon. In this case report, a 17-year-old Indian male is presented who reported chief complaints of a painless swelling in the posterior chest wall. A comprehensive lab workup ultimately resulted in a conclusive diagnosis. Following the national guidelines, the patient was started on an anti-tubercular treatment.
