Three cases with systemic rheumatic diseases who developed lung diseases compatible with BOOP were reported. Underlying diseases of these patients were: RA (1 case), SLE (2 cases). Respiratory symptoms were observed in one case such as dry cough at the time of diagnosis of BOOP. Chest radiography showed multiple infiltrates in 2 cases, bilateral reticular shadow in one case. In one case characteristic finding described as wandering shadow was observed. TBLB was done in 3 cases. Pathohistological findings were compatible with BOOP. Repeated bacteriological examinations failed to demonstrate specific organisms implicated for lung lesions. Cytological studies of sputum and TBLB specimens were all negative for malignancy. Antibiotic agents including anti-tuberculosis drugs were not effective for pulmonary diseases. Moderate doses of prednisolone were effective in 3 cases. Although the open lung biopsy has been recommended for establishment of diagnosis of BOOP, in patient with systemic rheumatic diseases this invasive procedure is not always easily performed. Further characterizations of clinical and laboratory features are indicated for noninvasive diagnosis of BOOP.
