Case Reports
[Secondary pulmonary hypertension due to pulmonary tumor thrombotic microangiopathy diagnosed by open lung biopsy].
A 67-year-old woman was admitted with progressive exertional dyspnea. Arterial blood gas analysis showed severe hypoxia. A chest radiograph and a computed tomography showed bilateral interstitial infiltrations and patchy ground-grass opacities. ⋯ Open lung biopsy was performed to establish a definitive diagnosis and to treat the diffuse lung disease. Microscopically, multiple tumor thrombi of mucinous adenocarcinoma were found in small sized pulmonary artery. Primary sites of malignancy has not been found in spite of postoperative examinations.

The patient was a 76-year-old man. He was referred to our hospital to treat Kommerell's diverticulum and aneurysmal right-sided aortic arch with aberrant left subclavian artery. ⋯ He was discharged uneventfully without any complication. Gull-wing approach method has an advantage of wide surgical field and may be useful for extensive thoracic aortic disease.

Case Reports
[Pulmonary metastasis fifteen years after hysterectomy for uterine leiomyosarcoma; report of a case].
A 75-year-old woman who had undergone a hysterectomy for uterine leiomyosarcoma 15 years before was noted to have a lung tumor on chest radiography. Chest computed tomography (CT) showed a tumor mass, 3.5 cm in size, in her left lung (S10). ⋯ The histopathological diagnosis was a metastasis of uterine leiomyosarcoma. The disease-free interval for this case was 15 years, which was. to our knowledge, the longest among previous reports of pulmonary metastasis of uterine leiomyosarcoma.
