[Recurrent pulmonary infarction associated with familial protein S deficiency type III].
A 38-year-old woman was admitted to our hospital because of recurrent chest pain and fever. Chest X-ray films and computed tomograms showed subpleural consolidation containing small cavity-like opacities. Open lung biopsy revealed non-infectious abscess and vessels with organizing thrombus. The patient was given a diagnosis of pulmonary infarction due to the existence of deep venous thrombosis. Coagulation studies demonstrated that she had decreased plasma protein S activity, whereas her free and total protein S antigen levels were normal. Because her mother and maternal uncle and aunt also demonstrated decreased protein S activity with normal plasma protein S antigen levels, the patient was considered to be affected by familial protein S deficiency type III.
