| Summary: | We report a case of post-traumatic tuberculosis verrucosa cutis. A 38-year-old man presented with a 20-year history of an annular plaque on the left buttock following a local trauma. Dermatological examination revealed an annular, infiltrated, dark red plaque with a raised border and central atrophic scar on the left buttock. Histopathological examination showed fibroplasia in the dermis and inflammatory granulomas with multinucleated giant cells. Acid-fast staining was negative. T-Spot test was positive. Mycobacterium tuberculosis DNA PCR was negative. Diagnosis: tuberculosis verrucosa cutis. Following 6-month anti-tuberculosis therapy, the lesion healed with residual scar and post-inflammatory hyperpigmentation. No recurrence was observed over 2 years of follow-up.
