[Birt-Hogg-Dubé Syndrome Diagnosed with Surgery;Report of Three Cases].

Birt-Hogg-Dubé (BHD) syndrome is an autosomal and predominantly inherited disorder. We report 3 cases of BHD syndrome. Case 1:A 24-year-old man was admitted to our hospital due to left-sided spontaneous pneumothorax. He had a previous drainage history of right-sided spontaneous pneumothorax. In operation, we resected the cyst at segment 8 of the left lung and covered the lung using polyglycolic acid( PGA) sheet. Case 2:A 47-year-old man was admitted to our hospital due to right-sided spontaneous pneumothorax. He had a previous surgical history of right-sided spontaneous pneumothorax and left-sided spontaneous pneumothorax. In operation, we resected the cyst at segment 8 of the right lung and covered the lung using fibrin glue-coated collagen fleece. Case 3:A 60-year-old man was admitted to our hospital due to left-sided spontaneous pneumothorax. He had 2 times of previous drainage history of left-sided spontaneous pneumothorax. In operation, we resected the cysts at lingular division of the lung and covered the lung using PGA sheet. On genetic analysis, all 3 cases were diagnosed with the BHD syndrome.
