Tuberculosis of Acromioclavicular Joint

Abstract

Tuberculosis (TB) arthritis accounts for approximately 1%–3% of all cases of TB and for approximately 10%–11% of extra pulmonary cases. Isolated acromioclavicular joint TB has been reported rarely with varied presentations as case series of one to three cases none of them being large studies. In our case, patient presented with pain in left shoulder since one month. Patient was investigated and was diagnosed to have acromioclavicular joint TB on basis of positive Acid Fast Bacilli (AFB) stain and cytology. Patient recovered well with antitubercular therapy. Thus, it is important to send Ziehl-Neelsen (ZN) stain in all cases in an endemic country like India.
