History of Lung Endometriosis 
                             Catamenial Pneumothorax

The first reported cases of this disease were in the 1930’s. Menstrual bleeding from a lung tumor associated with endometriosis was by Schwarz in 1938. A laboratory investigation by Hobbs and Bortnick in 1940 was able to produce pulmonary endometriosis in rabbits by intravenous infusion of endometrial tissue suspension. Bungeler and associates in 1939 reported autopsy findings of three small nodules of endometriosis on the right upper pleural surface in a 42-year-old woman. Nicholson in 1951 was the first to report histologically proven endometriosis in a clinical case of recurrent hemorrhagic pleural effusion. Many cases of endometriosis have been reported within the thorax in various sites: lung parenchyma, pleura, diaphragm, myocardium and bronchial tree. This has been referred to as Thoracic, Pulmonary, Extrapelvic and Lung Endometriosis. This disease is considered to be extremely rare, but actually it is, under recognized and under diagnosed.
