Abstract

A 40-year old woman had experienced repeated spontaneous pneumothorax on the right side at the beginning of each menstrual period for one year. The level of serum CA125 was high at 60 ng/ml. Right thoracotomy revealed the presence of multiple darkly-pigmented spots and several pinhole like perforations near the central tendon of the diaphragm. The partial resection of the diaphragm was done, endometrial tissues were detected histologically. Tha patient has been asymptomatic after operation and the level of serum CA125 is normal.
