Tuberculosis heralding connective tissue disorder.

Connective tissue diseases and infections are amongst the causes for organising pneumonia. However, organising pneumonia preceding other connective tissue disease manifestations is rare. is rarely associated with organising pneumonia. We report such a case. A 50-year-old diabetic male, a roadside shop keeper, a current smoker presented with fever, breathlessness, cough and weight loss for four months. Chest radiography demonstrated areas of consolidation with halo signs. Anti-nuclear antibody blot was positive for Scl-70 and Jo-1 suggestive of a syndrome of systemic sclerosis and polymyositis overlap. Fibre-optic bronchoscopy guided lung biopsy was suggestive of organising pneumonia, and broncho-alveolar lavage detected . should be investigated as an aetiology of organising pneumonia, as this may occur in unestablished cases of connective tissue disease even before clinical and radiological manifestations appear, as response can be achieved with anti-tuberculosis therapy alone, without additional use of systemic steroids.
