Recurrent cellulitis is one of the cutaneous tuberculosis mimickers. As the skin lesion can mimic other skin diseases, the diagnosis can easily be missed especially in immunocompetent patients without any other risk factors. We present a case of a 62-year-old lady with history of right hand extensor tenosynovitis presented with right hand and forearm swelling and pain, associated with fever. Clinically, her right hand and forearm were erythematous with a small nodule at the right elbow. She was treated for recurrent right upper limb cellulitis and thrombophlebitis complicated by septic shock needing several courses of antibiotics. However, she did not show any significant response to the treatment. Multiple septics work up were carried out and all were negative, except aspiration of her right elbow nodule was positive for Mycobacterium tuberculosis. Anti-tuberculous treatment was started but unfortunately, she succumbed due to nosocomial infection.
