We herein present two cases of spontaneous pneumothorax. The first one is occurring in an elderly female who has an extensive history of smoking and an underlying chronic obstructive lung disease, whereas the second case represents a congenital bleb in a male patient who has no other underlying pulmonary disorder. Both cases presented to our facility with a spontaneous pneumothorax following pulmonary bleb rupture. Both patients underwent thoracoscopic surgery with subsequent partial pleurectomy and pleurodesis.
