RESUMEN
Background/rationale: Tuberculosis is a public health issue. Extra-pulmonary presentations are rare and sometimes hard to diagnose and manage. Here, we report a case of tuberculosis of the chest wall in a 28-year-old man in order to discuss the mechanism, diagnostic and therapeutic problems posed by this rare localization. Description: The patient presented with wall swelling discovered after physical effort. Imaging was in favor of an abscess or infected hematoma. The excisional surgery established the tuberculous origin which was confirmed by histology. Anti-tuberculosis treatment during 9 months completed the surgical treatment and led to the patient's recovery. Discussion/conclusion: The rarity of this localization of tuberculosis should be investigated. Etiological treatment must be instituted and regular monitoring scheduled to avoid recurrence. Conclusion: Direct-acting antivirals are effective and characterized by good tolerance in these Malagasy hepatitis C patients.
