The estimated relative incidence of primary pulmonary sarcoma to lung cancer is 0.4%. Furthermore, osteogenic sarcoma of the pulmonary artery is extremely rare. We report a case of a 63-year-old woman who visited our emergency room with the chief complaints of chest pain, dyspnea and dizziness. On echocardiography, right heart failure due to acute pulmonary artery embolism was diagnosed and we performed emergency operation. After opening the main pulmonary artery trunk, we found a mass attached to the arterial wall and massive thrombi around the mass. The mass was diagnosed as primary pulmonary artery osteosarcoma through postoperative evaluation. The patient received chemotherapy and radiotherapy. The patient is alive without specific symptoms 16 months postoperatively.

We treated synchronous double primary lung cancers, where one site resulted from CIS disease, with lobectomy and argon plasma coagulation (APC) in a patient who couldn't tolerate pneumonectomy, which resulted in a reduction of the extent of surgery. APC could be a reasonable alternative for CIS disease of lung in inoperable patients.

병적인 고음성은 임상적으로 흔하지는 않지만 종종 볼 수 있는 질환으로서 치료에 대한 많은 논란이 있는 게 사실이다. 대개 음성교육에 의한 치료가 많이 시행되며 수술적인 치료로서는 제 3형 갑상연골성형술이 인정되어 온 것이 사실이다. 이러한 수술에 대한 적응증으로는 첫째 남자에서 오랫동안 너무 높은 음성(mutational voice disorder)을 가진 환자와 둘째 여러 가지 원인에 의해 성대가 너무 경직되어 고음이면서 애성(breathy voice)을 동반한 발성장애가 있겠다. (중략)

Background: Cryosurgery has been used to treat primary malignant pulmonary tumors at our institute since November 2004. In this study we analyzed our treatment results and complication rates. Material and Method: A retrospective study using medical charts and imaging data was conducted involving 17 patients with a total of 17 malignant pulmonary tumors who were treated between November 2004 and March 2007. Fourteen patients were males and 3 were females. The median age of the patients was 64 years (range, $54{\sim}77$ years). The average size of the tumors was 48.8mm (range, $36{\sim}111mm$) in diameter. The patients were followed with chest CT scans 7 days, 1 month, 3 months, and 6 months postoperatively. PET scans were obtained between 6 and 9 months postoperatively. The treatment response was analyzed according to the Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Result: Six months after treatment, 6 tumors (35.3%) showed a complete response, 4 (23.5%) had a partial response, 3 (17.6%) had stable disease, and 4 (23.5%) showed disease progression. In tumors <4 cm in diameter, a complete response was reported in 50% of the tumors. A $x^2$-test showed that in tumors <4 cm in diameter, the p-value for results better than a partial response was 0.034. With respect to procedural complications, there was 1 case of blood-tinged sputum which resolved spontaneously within 1 or 2 days, a spontaneously relieved case of subcutaneous emphysema, and 1 patient with a fever. There were no mortalities and the average hospital stay was 6.3 days. Conclusion: The effects of cryosurgery on primary lung cancer is greatest in patients with small tumors. Considering the facts that cryosurgery is minimally invasive, has a low complication rate, and can be performed repetitively, we believe that it may play an important role in the treatment of high risk lung cancer patients.

Primary malignant melanoma of the vagina is an extremely rare genital neoplasm occurring mainly on postmenopausal women. It has a worse prognosis than cutaneous melanomas, because of the high rate of loco-regional recurrences and rapid systemic dissemination. In the past, radical surgical extirpation as the primary management had been recommended to improve loco-regional control, and possibly overall survival. However, the prognosis was poor In spite of such a radical approache. Recently, more conservative treatment such as wide local excision combined with adjuvant high-dose fraction radiotherapy seems to have premising results. Primary radiation therapy could be served as an alternative to surgery for patients with lesion less than 3 cm in diameter. We report 2 cases of primary vaginal malignant melanoma treated with radiotherapy.
