  • Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.

  • Carcinosarcoma is an unusual and rarest neoplasm in man, consisting of carcinomatous parenchyme and sarcomatous stroma. Two clinical types of carcinosarcoma were present. One type of tumor was centrally located [endobronchial type], infrequent metastasis, and better prognosis than parenchymal type. The other type was peripherally located [parenchymal type], frequent metastasis, and poor prognosis. The histogenesis of carcinosarcoma is many hypothesis, but controversial; 1] sarcomatous degeneration of stroma, 2] intermingling of simultaneously arising carcinoma & sarcoma, 3] multiple primary tumor, 4] blastomatous changes in hamartoma, 5] stromal reaction to squamous cell carcinoma, 6] true & collision carcinosarcoma. In this case, 52 year-old male patient was hospitalized due to intermittent hemoptysis & known pulmonary lesions. Since 1968, chest PA showed round haziness within cyst & multiple cyst on RUL & RLL. Radical pneumonectomy was performed and histopathology showed carcinosarcoma, surrounded by bronchial epithelium. The patient maintain general well-being without clinical evidence of recurrence till now.

  • Background: Many institutes are interested in lung metastatectomy than before because of the improved long term survival, low mortality, and low morbidity after lung metastatectomy. However, prognostic factors affecting long term survival are controversial. We attempt to analyze the prognostic factors affecting retrospectively by comparing the results of lung metastasectomy. Material and Method: Between Jan. 1990 and Dec. 1997, 74 operations were taken in 63 patients with pulmonary metastases in various primary sites. We analyzed the postoperative long term survival according to sex, cell type, laterality, disease free interval(DFI), operation, the number of metastases, and the size of the largest metastasis. Result: There were 27 male and 36 female patients. Sex did not appeared to affect survival time(p=0.849). The primary tumor was carcinoma in 32, sarcoma in 28, and others in 3. Cell type, considering carcinoma and sarcoma, did not relate to survival time(p=0.071). DFI had no influence on the outcome(p=0.902). The type of operative procedure had no influence on the outcome(p=0.556). The laterality of metastases, 47 unilateral(74.6%) and 16 bilateral(25.4%), had no influence on the outcome(p=0.843). The number of metastases excised(one, two or three, four or more) did not appear to affect survival(p=0.263). The size of largest metastasis(<=10mm, 11mm-30mm, and >30mm) did not appear to affect survival(p=0.751). Previous factors were evaluated in both the carcinoma and sarcoma patients respectively. DFI was the only significant prognostic factor in metastatic lung sarcoma(p=0.0026). Conclusion: Survival was not related to sex, cell type, laterality, DFI, operative procedure, number of metastases, nor the size of the largest metastasis. DFI was related to the survival time in sarcoma group but further study is needed.

  • 원발성 페평활근육종은 원발성 폐종양으로써 매우 드문 질환으로 대부분 기관지나 혈관들의 평활근에서 기시하나 드물게는 말초부에서도 생긴다고 한다. 이 드문 종양은 기관지종양과 유사하며, 국소적 혹은 전신적인 증상을 보인다고 하며, 관례적인 흉부방사선검사상 우연히 발견되기도 한다. 본원의 경우 61세의 남자환자에서 우연히 흉부방사선 검사상에 좌측 폐 말초부에서 발견된 큰 종괴가 발견되어 좌 전폐절제술을 시행하였으며, 이의 조직검사상 원발성 폐 평활근육종으로 술후 경과는 양호하였다.

  • Recently we experienced four cases of soft tissue Ewing sarcoma, developed in the calf muscles in two cases, and one case each in the foot and suprascapular region. We also found that the clinical course in all cases was rather rapid, because of local recurrence and metastatic lesions developing within a few months, followed by the patients' death in about 2 years after the primary tumor was excised. These cases were improperly treated initially as some kind of benign soft tissue tumor. The delay led to missed early accurate diagnosis and was thought to be one of the main causes for the rapid local recurrence and metastasis after tumor excision. The pulmonary metastasis was the most common cause of death.

  • Excision of the metastatic pulmonary sarcoma or carcinoma in the selected cases is now the accepted and the most effective method of treatment. From January 1978 to July 1987, 14 patients with metastatic lung cancer were treated surgically at the Department of Thoracic and Cardiovascular Surgery, Catholic University Medical College. Ages ranged from 26 years to 68 years [mean=38.0 years]. Primary sites were uterus in 6 patients, colorectum in 2, sarcoma of extremities in 2, and 1 case of pancreas, kidney, skin and melanoma of hand. Fourteen posterolateral thoracotomies were done and resected the 36 metastatic masses in 14 patients. Surgical mortality was none. The performed procedures of resection were as follows; lobectomy with wedge resection in 2, lobectomy in 3, segmentectomy in 1 and wedge resection in 8. Eleven patients were received radiotherapy or chemotherapy, or both postoperatively. Among the 14 patients, there were 5 survivors. They are 6, 7, 21, 35, and 63 months postoperatively. Among them, 9 patients were dead. Within one year in 2, two years in 6, and three years in l.

  • Kaposiform hemangioendothelioma (KHE) is a rare, locally aggressive vascular tumor of intermediate malignancy with resemblance to Kaposi sarcoma. It occurs predominantly in pediatric age groups as a cutaneous lesion with focal infiltration into the adjacent soft tissue and bone. Although visceral involvement is very uncommon, several cases with bone, retroperitoneal, or mediastinal involvement have been described. KHE has been reported to occasionally occur in unusual sites such as the thymus, tonsils, larynx, paranasal sinuses, deltoid muscle, spleen, uterine cervix, thoracic spine, and even the breast. Multifocal KHE is an extremely rare entity with few reports available in the literature, none of which describes pulmonary involvement. Herein, we report a unique case of multifocal KHE in a 13-year-old boy presenting with a huge soft tissue mass in the upper extremity complicated by bilateral pulmonary nodules that developed into large, necrotic tumor masses.

  • Bronchoplastic procedure has been considered as an appropriate surgery for traumatic bronchial disruption and occasionaly for primary bronchial tumors or tuberculosis because it can bring preservation of pulmonary tissue for patients without compromising the chance for cure. Nowadays bronchoplastic procedure is also applicable for the selected cases of bronchogenic carcinomas with favorable long term survival, when compared to standard pneumonectomy.Eighteen bronchoplastic procedures were performed with or without pulmonary resection at Department of Thoracic and Cardiovascular Surgery, Catholic University Medical College, between 1990 and 1994. The patients were 11 men and 7 wemen with average age of 57 years [range, 19 to 71 years . Tumor comprised 56% of the lesions, including 6 squamous cell carcinoma [33% , 2 bronchial adenoma [11% , 1 leiomyoma and 1 metastatic osteogenic sarcoma. Cicatrical stenosis secondary to endobronchial tuberculosis and traumatic disruption occurred in 6 [33% and 1 patient respectively.Applied bronchoplastic procedures were as follows ; sleeve lobectomy, 8 cases [right upper : 6, left upper : 1, right middle : 1 : bronchial segmental resection without pulmonary resection, 2 cases : sleeve bi-lobectomy, 1 cases :patch dilating bronchoplasty with or without concomitant lobectomy in 7. There was no perioperative mortality. Morbidity in 4 patients included 1 transient recurrent laryngeal nerve palsy, 1 unstability of bronchial patch resulting atelectasis of afftected lung and 2 bronchial stenosis of anastomotic site.Throughout our experiences, we feel strongly that bronchoplastic procedure is a safe and effective surgical method preserving normal pulmonary tissue below affected bronchus for the wide range of various bronchial lesion including selected cases of bronchogenic carcinoma with acceptable complication and mortality.
