Management of two pregnancies in a woman with mixed connective tissue disease, pulmonary fibrosis, frequent pneumothorax and oxygen inhalation therapy along with a published work review.

Two pregnancies in a woman on oxygen inhalation therapy before pregnancy, due to pulmonary fibrosis and frequent pneumothorax that are secondary to mixed connective tissue disease, were managed safely. As usual for this condition, the patient was rather older and her ordinary daily life was restricted. This is a truly very rare case of a successful pregnancy in these circumstances. In a published work review using key words such as "pregnancy", "mixed connective tissue disease" and "oxygen inhalation therapy", no similar case could be found. For the management of such high-risk patients, close cooperation of the obstetrician, clinical immunologist, clinical pneumologist and neonatologist in the same hospital is indispensable.
