Primary cardiac tumors are extremely rare and can originate within the heart or be the result of tumor spread from other sites. We report a female patient with a pulmonary vein tumor extending into the left atrium that had a suspicious primary malignant origin with a sacral metastatic carcinoma. The patient was admitted complaining of pain in her buttock area as a result of a sacral tumor. It was believed that the sacral tumor was a metastasis from the imaging study and clinical manifestation. The primary malignant origin was evaluated. The chest CT showed a left atrium thrombus-like lesion without a pulmonary abnormality. After a transesophageal echocardiogram, the patient was diagnosed with a pulmonary vein tumor extending to the left atrium. The patient was given palliative radiotherapy for the sacral pain. Initially, the clinical impression was a metastatic sacral tumor with a thromboembolism of the left atrium. However, this patient was finally diagnosed with a pulmonary vein tumor with a left atrium extension by a transesophageal echocardiogram.

Wilms' tumor is the most common urinary tract neoplasm and one of the most frequent solid abdominal malignant tumors of childhood, usually diagnosed between the ages of 2 and 5 years. Typically, it is manifested as an asymptomatic unilateral or upper abdominal mass. Abdimonal pain after some traumatic incident, fever, anemia, hematuria and hypertension are other patterns of presentation. In a considerable number of these patients, pulmonary metastases are present at the time of primary diagnosis. But, the initial presentation of acute pulmonary tumor emboli without surgical manipulation is very rare. We describe a sudden unexpected infantile death case diagnosed as pulmonary tumor embolism preexisting Wilms' tumor. To our knowledge, this is the initial autopsy presentation of Wilms' tumor with tumor embolism as sudden and unexpected death in Korea.

Sudden isolated pulmonary metastasis from malignant fat-forming solitary fibrous tumor of thigh : a case report

( Kyung Jun Heo ),( Jae Seok Jeong ),( So Ri Kim ),( Yong Chul Lee ) 대한결핵 및 호흡기학회 2019 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.127 No.-

Fat-forming solitary fibrous tumor(SFT) is generally slow-growing neoplasm and shows benign histology. Rarely, some fat-forming SFTs show malignant characteristics. An 87-year-old man visited our hospital complaining of dyspnea. 36months ago, he underwent wide excision for malignant SFT of thigh. The patient was followed postoperatively and there was no evidence of metastasis for 14month. But new mass was detected on right lung. It was metastasis of malignant fat forming SFTs. The patient died 1month after diagnosis. In this report, we describe, for the first time, a case of sudden isolated pulmonary metastasis from malignant fat-forming solitary fibrous tumor.

Sudden Unexpected Death During Bronchoscopy of a Patient with Pulmonary Lymphangitic Carcinomatosis and Pulmonary Tumor Thrombotic Microangiopathy due to Gastric Cancer

박소형,나주영,최병하 대한법의학회 2019 대한법의학회지 Vol.43 No.4

We present the case of a 48-year-old woman who complained of sustained dyspnea and newly developed dyspnea, who then suddenly and unexpectedly expired during bronchoscopy. On postmortem examination, the deceased had advanced gastric cancer as a primary tumor. Frequent lymphatic tumor emboli were observed with some pulmonary lymphangitic carcinomatosis (PLC), and pulmonary tumor thrombotic microangiopathy (PTMA). PLC and PTMA are lethal forms of pulmonary metastasis, and PTMA can lead to sudden death. The characteristic findings of PLC and PTMA in the deceased were not predominant, however, and the clinical manifestation was not acutely deteriorating. These findings are, therefore, insufficient to explain the deceased’s sudden death. Clinically, the deceased manifested hypoxemia, bradycardia and cardiac arrest during bronchoscopy and then soon expired, suggesting the possibility of cardiovascular complication related to bronchoscopy. Despite several limitations, we assumed that the sudden unexpected death might have been induced by cardiovascular complications related to bronchoscopy and due to the underlying pathologic condition by PLC and PTMA.

이가원,김태우,강민희 한국임상수의학회 2018 한국임상수의학회지 Vol.35 No.3

A nine-year-old spayed female Turkish angora cat presented for evaluation of anorexia, lethargy, vomiting,ptyalism and jaundice. Based on clinical examinations including laboratory examinations, concurrent inflammatorycondition of the biliary system, pancreas and intestines (triaditis) was suspected. The cat was under antibiotic andimmune-suppressive therapy, but there was no response. Further examination revealed the possibility of malignanthepatobiliary tumor with pulmonary metastasis. The condition of the cat continued to deteriorate and the cat died 3weeks after the diagnosis. This case demonstrates the clinical findings of triaditis combined with suspected malignanthepatobiliary tumor.

A Case Report: Cavitary Infarction Caused by Pulmonary Tumor Thrombotic Microangiopathy in a Patient with Pancreatic Intraductal Papillary Mucinous Neoplasm

Pulmonary tumor embolism is commonly discovered at autopsy, but is rarely suspected ante-mortem. Microangiopathy is an uncommon and distinct form of simple tumor pulmonary embolism. Here, we present a 52-year-old male with tumor thrombotic microangiopathy and pulmonary infarction, which might have originated from intraductal papillary mucinous tumor of the pancreas. Multiple wedge-shaped consolidations were found initially and aggravated with cavitation. These CT features of pulmonary infarction were pathologically confirmed to result from pulmonary tumor thrombotic microangiopathy.

Primary Pulmonary Glomus Tumor, Diagnosed byPreoperative Needle Biopsy: Report of One Case andLiterature Review

김미진,성우정 대한병리학회 2008 Journal of Pathology and Translational Medicine Vol.42 No.1

Glomus tumors commonly occur in dermal and subcutaneous tissue in the subungal region of a finger. Some glomus tumors occur extracutaneously, including lung. Only 15 cases of primary pulmonary glomus tumor have been described in literature. In this report, we describe a case of primary pulmonary glomus tumor, which is the first case diagnosed before surgical resection. A 51-year-old man underwent a needle biopsy of a well defined coin-like mass in left lower lobe of the lung on chest radiography. Microscopic examination revealed a tumor composed of perivascularly arranged round to ovoid epithelioid cells with abundant eosinophilic cytoplasm. Tumor cells are immunoreactive for smooth muscle actin and vimentin, but negative for desmin, cytokeratin (AE1/AE3), chromogranin, or synaptophysin. A diagnosis of glomus tumor was then made. The lung mass was resected by wedge resection after being diagnosed by preoperative lung needle biopsy. Although primary pulmonary glomus tumor is rare, most cases follows a benign course. For proper treatment of the patient, glomus tumor should be considered as a differential diagnosis of solitary lung mass.

이승숙,하승연,강명희,안정석,노미숙,하창원,한정호 대한병리학회 2013 Journal of Pathology and Translational Medicine Vol.47 No.1

Background: Few studies on how to diagnose pulmonary neuroendocrine tumors through morphometric analysis have been reported. In this study, we measured and analyzed the characteristic parameters of pulmonary neuroendocrine tumors using an image analyzer to aid in diagnosis. Methods: Sixteen cases of typical carcinoid tumor, 5 cases of atypical carcinoid tumor, 15 cases of small cell carcinoma, and 51 cases of large cell neuroendocrine carcinoma were analyzed. Using an image analyzer, we measured the nuclear area, perimeter, and the major and minor axes. Results: The mean nuclear area was 0.318±0.101 μm2 in typical carcinoid tumors, 0.326±0.119 μm2 in atypical carcinoid tumors, 0.314±0.107 μm2 in small cell carcinomas, and 0.446±0.145 μm2 in large cell neuroendocrine carcinomas. The mean nuclear circumference was 2.268±0.600 μm in typical carcinoid tumors, 2.408±0.680 μm in atypical carcinoid tumors, 2.158±0.438 μm in small cell carcinomas, and 3.247±1.276 μm in large cell neuroendocrine carcinomas. All parameters were useful in distinguishing large cell neuroendocrine carcinoma from other tumors (p=0.001) and in particular, nuclear circumference was the most effective (p=0.001). Conclusions: Pulmonary neuroendocrine tumors showed nuclear morphology differences by subtype. Therefore, evaluation of quantitative nuclear parameters improves the accuracy and reliability of diagnosis.

갑상선 유두암 환자에서 발생한 종양색전증 1예

이정규,곽동신,김재하,여유미,김상헌,손장원,윤호주,신동호,박성수,곽현정 대한노인병학회 2013 Annals of geriatric medicine and research Vol.17 No.3

The tumor embolism is defined as tumor cells within the vascular system such as pulmonary artery that is not contiguous with the other metastatic foci. The incidence of tumor embolism varies widely ranging from 3% to 26% among seve ral studies; whereas lung cancer, prostate cancer, colorectal cancer, breast cancer, pancreas cancer are associated with high risks for tumor embolism. However thyroid cancer is rarely associated with tumor embolism. Among the rare cases, tumor embolism was reported as being mostly of follicular carcinoma or undifferentiated carcinoma, but few of papillary carcinoma. We report an unusual presentation that pulmonary tumor embolism from thyroid papillary carcinoma was diagnosed with positron emission tomography/computed tomography (CT) and chest CT.

태아폐를 닮은 폐 내배엽 종양 : 1예 보고 Report of a case

임현이,류한영,최호,임상현,소동문,이철주,심철,전미선 아주대학교 의과학연구소 1996 아주의학 Vol.1 No.1

We report a case of pulmonary endodeimal tumor resembling fetal lung in a 35 year-old woman, who complained of cough with sputum for 6 months. Pulmonary endodermal tumor is a very rare neoplasm of the lung and it is exclusively composed of complex branching tubules resembling the canalicular stage of fetal lung, lacking sarcomatous component of pulmonary blastoma. Prognosis of this tumor after adequate resection appears to be better than that for biphasic pulmonary blastoma.
