Pulmonary sclerosing pneumocytoma (PSP) is a tumor of pneumocytic origin that is classified as a benign neoplasm. To date, aggressive behavior of this tumor has rarely been reported. Here, we describe a case of a 56-year-old woman with a huge, 19-cm PSP that resulted in mediastinal shift and showed microscopic endobronchial invasion and necrosis. The differential diagnosis included malignant mesenchymal tumors, such as solitary fibrous tumor; however, PSP was confirmed based on the characteristic thyroid transcription factor 1 positivity and membranous expression of Ki-67 on immunohistochemical staining of tumor cells.

70세 남자 환자가 심한 복부 및 배부 통증으로 흉부 대동맥류 파열 의심 하에 전원되었다. 환자는 6개월 전 타 병원에서 하행대동맥류 의심 하에 대동맥 스텐트를 삽입하였던 병력이 있었으나 전산화 단층촬영 소견은 후종격동 악성 종양을 시사하였다. 개흉 후 이와 같은 진단이 확인되었으며 종격동의 육종은 거기에 둘러싸인 대동맥과 함께 성공적으로 절제되었다. 본 증례는 최근 주목을 받고 있는 대동맥 스텐트 그라프트 삽입에 대한 맹목적인 선호에 대하여 주의를 환기시키는 교훈적인 경우라고 판단된다.

Background: Complete surgical excision is the only curative treatment for primary cardiac tumors. For wide excision, interatrial septal reconstruction (ISR) is commonly performed. We hypothesized that ISR may increase the risk of postoperative atrial tachyarrhythmia (AT) after surgical resection of cardiac myxoma. Methods: After excluding patients with a history of cardiac surgery and concomitant procedures unrelated to tumor resection and those with AT or permanent pacemakers, we finally enrolled 272 adult patients who underwent benign cardiac tumor surgery from 1995 to 2021 at our institution. They were divided into the ISR (n=184) and non-ISR (n=88) groups. The primary outcome was postoperative new-onset AT. Results: The study cohort predominantly consisted of women (66.2%), with a mean age of 57.2±13.6 years. The incidence of postoperative new-onset AT was 15.4%. No 30-day mortality or recurrence was observed. The cardiopulmonary bypass time and aortic cross-clamping time were significantly longer in the ISR group than in the non-ISR group (p<0.001). The median duration of hospital stay of all patients was 6.0 days (interquartile range, 5.0-7.0 days), and no significant difference was observed between the 2 groups (p=0.329). ISR was not an independent predictor of new-onset AT (p=0.248). Male sex and hypertension were found to be independent predictors of new-onset AT. Conclusion: ISR was not a significant predictor of postoperative new-onset AT. ISR might be a feasible and safe procedure for surgical resection of cardiac myxoma and should be considered if needed.

This report is a analysis of 72 cases of mediastinal tumors which are originated in mediastinum or probably metastasized from other organs, and classified on the basis of histopathological types. And all are experienced in the Depart. Thoracic and cardiovascular Surgery, National Medical Center from 1959 to April 1976. Among these cases, 58 cases were confirmed by histopathologically, and remained 14 cases were considered as mediastinal tumor by clinically and roentgenologically. In this series, dermoid cyst and teratoma was most frequent tumor among histopathologically confirmed cases(27.6%), and thymoma 20.7%, neurogenic tumors 17.2%, carcinoma 19%, lymphoid tumor 8.6% and others was 5.9%. The cases of not verified histopathologically were 14 cases. The main clinical symptoms were dyspnea on exertion or orthopnea (62.55%), productive or irritative cough (59.77%), decreased breathing sound (43. 09%). S.V.C syndromes was seen in 25.02%, and there were no definitive symptom in 4.2% of all cases. The main treatment method was surgical removal and irradiation therapy.

Nerogenic tumor of various histologic types may arise in the posterior mediastinum. Mediastinal schwannoma is a frequent paraspinal neurogenic tumor, but malignant mediastinal schwannoma is rare tumor which is derived from Schwann cells. Although there are some reports dealing with approach for screening patients with symptoms suggesting malignancy and the imaging criteria for distinguishing malignant from benign schwannoma but the results are not clearly defined. We present a case of hugh mediastinal schwannoma which was taken for malignancy in imaging studies because of its invasiveness.

Atypical thymic carcinoid is an extremely rare tumor with a poor prognosis. In addition to its known association with multiple endocrine neoplasia type 1, its hallmark characteristics include local invasion and early distant metastasis. In this report, we share our experience treating atypical thymic carcinoid in a patient with Zollinger-Ellison syndrome.

심장에 발생하는 원발성 악성종양의 발생빈도는 아주 낮게 보고되고 있으며, 국내의 증례보고도 미미한 수준이다. 29세 남자 환자가 최근 2개월간 점증되는 심계 항진과 운동 시 호흡곤란으로 본원 심장내과에 내원하여 검사를 진행하던 중에 심초음파상에 좌심방내의 종괴가 발견되어 좌심방점액종으로 진단하고 긴급수술로 개심술하에 종양절제술을 시행하였다. 수술소견에서 35$\times$90$\times$50 mm의 점액성 종양의 기저부가 광범위하게 좌심방후벽과 우상폐정맥의 입구로 침윤되어 있었으며 단순박리로 종양은 절제되었으나 좌심방후벽과 우상폐정맥,그리고 좌하폐정맥의 입구의 종양의 침윤을 육안으로 확인하였다. 수술 후 병리조직 검사 결과 악성 점액섬유성육종으로 진단되었다. 환자는 수술 후 18일째에 경쾌 퇴원하였으며, 수술 후 방사선치료와 6차례의 항암제 치료를 진행하여 술 후 10개월 간 추적 관찰에서 재발이나 전이의 소견 없이 잘 생활하고 있다.

악성 고립성 섬유종은 비교적 드문 종양으로 흉막, 횡격막, 후복막 및 심낭 등에서 발생할 수 있으며, 남녀 발생 빈도는 비슷하고 60~70세 사이에 호발하나 10대의 어린 나이에도 발생하는 경우가 있다. 17세 남자에서 악성 고립성 섬유종에 의해 인접한 좌측 9번째 늑골의 형태학적 변화가 있어 섬유종의 제거 및 늑골 근위부의 부분적 절제술을 시행하였다. 술 후 뇌척수액의 흉강 내로의 누출을 CT myelography로 확인 후 뇌척수액의 배액 및 부분적 반측 추궁 절제술 및 경질막 복원술을 통한 교정을 치험하여 발표하고자 한다.

The primary cardiac tumor was considered as a form of disease with poor prognosis in the past and it was hardly diagnosed before post mortem autopsy. But recent development of diagnostic procedure and the cardiac surgery using extracorporeal circulation increased the accuracy of diagnosis and the opportunity of successful treatment. The authors present two cases of left atrial myxoma which experienced during recent 4 years between 1979 and 1982. A 33 year old woman admitted with severe shortness of breath, generalized edema, ascites and the evidence of hepatopathy resulted from right sided heart failure. Preoperatively, the patient was treated with conservative medication to improve general condition for a few days. The tumor mass was removed successfully under the cardiopulmonary bypass. She, however, died of myocardial dysfunction showing low blood pressure. The tumor mass weighed 22gm and measured 5.2x4.5x3.6 cm in size. A 60 year old man admitted with shortness of breath on exertion and an episode of fainting. Following the removal of tumor mass under the cardiovascular bypass, the clinical course was satisfactory with no complication. The tumor mass weighed 105gm and measured 9x4x5 cm in size.
