Dynamics of diaphragmatic endometriosis with thoracic endometriosis-related pneumothorax

Diaphragmatic endometriosis frequently invades the thoracic cavity at the ventral side of diaphragm membrane. Hiatus lesions are unique to diaphragmatic endometriosis. The synergistic effect of physical traction during the respiratory movement of the diaphragm and the protein dissolution phenomenon of endometrial tissue engraftment may possibly form hiatus lesions.
