Introduction:
Cutaneous tuberculosis (CTB) is a rare form of extrapulmonary tuberculosis (TB), accounting for only 1% to 2% of all extrapulmonary cases. It typically affects the face, and to a lesser extent, the neck or chest, with a higher incidence among young women. In Malaysia, TB is endemic; however, CTB involving the pinna is exceptionally rare. Consequently, there is often a delay in diagnosis and treatment due to frequent.

Aim:
This case report aims to emphasize the presentation, diagnosis, and subsequent management of cutaneous pinna tuberculosis, supplemented by a review of the existing literature on this disease.

Case study:
We present an 83-year-old patient with painful left auricular swelling and deformity and pus discharge for 4 months. His condition did not improve despite prolonged antibiotics treatment and multiple incision and drainage done.

Results and discussion:
Examination under anaesthesia, wound exploration extended incision and drainage was performed, revealing auricular cartilage necrosis, tissue biopsy confirmed the presence of Mycobacterium tuberculosis.

Conclusions:
(1) A non-healing auricular wound despite adequate antibiotics treatment should raise suspicion of TB. (2) Bactec is the most rapid and sensitive culture for tuberculosis. (3) Complications of pinna TB include pain, non-healing wound and permanent ear deformity.
