[A case of pulmonary sarcoidosis with calcification in the lung]

A 35 year-old male farmer presented with complaints of productive cough and sputum. The chest X-ray films showed reticulonodular shadows bilaterally in the upper and middle lung fields, segmental infiltration in the right lung, and no BHL. Tuberculin reaction was negative. Serum angiotensin converting enzyme level was 26.5 IU/ml. Precipitating antibodies for Thermophilic actinomycetes and M.f. were negative. BAL showed moderate lymphocytosis (24.3%), and CD 4/8 was 1.67. A biopsy specimen of right scalene lymph node showed epithelioid cell granulomas and TBLB epithelioid cell granulomas and spot-like calcification. Pulmonary sarcoidosis with calcification in the lung is very rare.
