BACKGROUND Tuberculosis(TB)is a widespread infectious disease,with an incidence that is increasing worldwide.Cutaneous TB(CTB)occurs rarely,accounting for less than 1%of all TB cases.Due to the clinical presentation and diagnostic difficulties,CTB is often clinically neglected and misdiagnosed.CASE SUMMARY A 32-year-old man underwent several debridement surgeries and skin flap transplantation after trauma.The wound remained unhealed,accompanied by sinus formation.According to empirical judgment,T-cell spot of TB test,and bacterial culture of pyogenic fluids,he was diagnosed with CTB due to infection with exogenous Mycobacterium tuberculosis.A comprehensive anti-TB regimen that included isoniazid,rifampicin,ethambutol,and pyrazinamide was applied.The sinus was filled with a hydrophilic fiber-containing silver dressing,and woundprotecting sponges were applied to part of the wound.The wound healed after 40 d.No ulceration was found within 2 mo after discharge;further follow-up will be conducted.CONCLUSION A non-healing wound may be caused by TB infection.Comprehensive treatment of CTB is effective.
