Mediastinal teratomas are rare and represent less than 10 per cent of all mediastinal tumors. Almost all arise in the anterosuperior mediastinal compartment, and most symptoms, when present, result from compression of adjacent structures. They contain different tissues derived from all three germinal layers, with the prevalence of ectodermal elements which can include hair, teeth and sebaceous material. Benign teratomas may rupture into adjacent organs. Up to 36% of all mediastinal teratomas rupture, most frequently into the lung and bronchial tree, followed by the pleural space, pericardial space, or great vessels. The signs and symptoms of a ruptured teratoma vary with the structures involved. We report a case of mediastinal teratoma ruptured spontaneously in a 18 year old female who experienced 4 or 5 times of hemoptysis for 1 year and sudden onset of pleural effusion, pericardial effusion and pneumonia.

Background: Pericardial effusion (PE) is a serious condition in cancer patients, primarily arising from malignant dissemination. Pericardial window formation is a surgical intervention for refractory PE. However, the long-term outcomes and factors associated with postoperative survival remain unclear. Methods: We retrospectively analyzed data from 166 oncology patients who underwent pericardial window formation at Samsung Medical Center between 2011 and 2023. We analyzed survival and PE recurrence regarding surgical approach, cancer type, and cytopathological findings. To identify factors associated with survival, we utilized Cox proportional-hazards regression. Results: All patients had tumors documented in accordance with the American Joint Committee on Cancer staging manual, including lung (61.4%), breast (9.6%), gastrointestinal (9.0%), hematologic (3.6%), and other cancers (16.4%). Surgical approaches included mini-thoracotomy (67.5%) and thoracoscopy (32.5%). Postsurgical cytopathology confirmed malignancy in 94 cases (56.6%). Over a median follow-up duration of 50.0 months, 142 deaths and 16 PE recurrences occurred. The 1-year overall and PE recurrence-free survival rates were 31.4% and 28.6%, respectively. One-year survival rates were significantly higher for thoracoscopy recipients (43.7% vs. 25.6%, p=0.031) and patients with negative cytopathology results (45.1% vs. 20.6%, p<0.001). No significant survival difference was observed between lung cancer and other types (p=0.129). Multivariate analysis identified New York Heart Association class, cancer stage, and cytopathology as independent prognostic factors. Conclusion: This series is the largest to date concerning window formation among cancer patients with PE. Patients' long-term survival after surgery was generally unfavorable. However, cases with negative cytopathology or earlier tumor stage demonstrated comparatively high survival rates.

Fourteen cases of pericardia I tumor were clinically experienced from June 1966 to July 1981, for 15 years in St. Mary's Hospital, Department of Thoracic and Cardiovascular Surgery, Catholic Medical College. There were three primary tumors of the pericardium, liposarcoma, teratoma and malignant mesothelioma, and 11 metastatic pericardial tumors. In metastatic pericardial tumors, eight were originated from the lung, one was breast, and the other two cases were unknown origin. There were 6 adenocarcinoma, one small cell carcionoma ~nd one alveolar cell carcinoma in 8 cases from the lung, and 5 male and 3 female patients were composed the metastatic pericardial cancer from the lung. In clinical symptoms were dyspnea in all cases, and 9 cases had the generalized edema and enlarged liver size. Six patients had been operated, three of the primary pericardial tumor and three of metastatic pericardial tumor. Two of the primary tumors were cured satisfactorily by the mass removal, but one died due to cardiac arrest at postoperative one day. In metastatic tumors, operation were performed as two pericardial window formation and one left lower lobectomy with pericardial fenestration, but one was died in second operative day. Other nine metastatic tumors were diagnosed by needle biopsy in one case and by cell block of effusion in eight cases.

We had experienced a case of pericarditis associated with Mycoplasma and Salmonella co-infection. This 5-year old boy presented with high fever and generalized tonic-clonic seizure. The diagnosis was based on the markedly increased serial titer of Widal test and cold agglutinin with Mycoplasma indirect hemmagglution test during hospitalization. The electrocardiogram revealed P-R interval prolongation and an echocardiogram revealed moderate pericardial effusion. The patient treated with ceftriaxone and erythromycin for 2 weeks, and responded to the treatment well. We report this case with brief review of the related literatures.

Acute purulent pericarditis, though not common in incidence after introduction of antibiotics, is still potentially life treating isease. Since 1971, we have experienced 14 cases of acute purulent pericarditis with successful treatment. Among these 14 cases, 9 cases were male and they had high occurrence on their third to fifth decades in age distribution. Isolation of causative organisms were obtained in 11 cases through the bacterial culture of infectious source which was mainly pericardial effusion or blood, and the most frequently recovered organism was the staphylococcus aureus. Pre-existing inflammatory disease preceding to pericarditis, named as antecedent disease, were proved in 12 cases, and among which contiguous extension from the intrathoracic infection such as pneumonia or empyema accounted for the majority of antecedent disease. Pericardiocentesis with administration of antibiotics were tried in all cases, but result in recovery in 1 patient only. Remaining 13 cases had persistent picture of pericarditis and necessitated surgical drainage procedure. Ten of these 13 cases were underwent the open pericardial window using a mode of anterior approach in 4 and subxiphoid approach in 6 cases respectively. Two cases of subxiphoid group were reoperated by the anterior interphrenic pericardiectomy, due to insufficient drain of too thick effusion. In remaining 3 cases, anterior interphrenic pericardiectomy was performed initially because of purulent effusion already changed into fibrinopurulent peel with thickened pericardium. Through the experience of this series, we recommended that pericardiectomy should not be reluctant in purulent pericarditis as a initial surgical procedure for advantage of complete removal of infected space and avoidance of late constrictive pericarditis.

Group A streptococcus, also known as Streptococcus pyogenes, is a common bacterial pathogens of the upper respiratory tract and skin infections in children, but this organism is a less common cause of pneumonia, pericarditis. However, pneumonia that is caused by Streptococcus pyogenes, may be rapidly progressive course with developing severe consequences. It may be focal but often is bilateral and diffuse involvement of lung. Empyema is commonly developed, and pleurocentesis often yields thin, watery fluid that continues to flow out when a chest tube is inserted. Antimicrobial resistance to the ${\beta}$-lactam antibiotics has not been reported against group A streptococci, whereas increasing resistance to the macrolides seems to be directly related to the consumption of specific antimicrobial agent use in the community. Clindamycin resistance is uncommon but does occur. We experienced one case of group A streptoccoccal pneumonia with empyema and pericardial effusion, and treated successfully with amoxicillin-clavulanate, clindamycin and roxithromycin.

A 12-year-old castrated male Pekingese dog was presented with weakness, exercise intolerance, and an episode of coughing started 2 weeks earlier upon presentation. Physical examination revealed a grade II/VI left systolic heart murmur. Echocardiographic examination revealed a pericardial effusion and a mass at the heart base located beside the left atrium. The mass beside the left atrium was also visible on the thoracic radiograph after drainage of the pericardial effusion. An aortic body tumor was definitely diagnosed based on postmortem histopathological examination and immunohistochemical staining for specific markers. The dog lived 234 days after diagnosis with only medical management and without recurrence of the pericardial effusion.

Primary malignant neoplasm of the pericardium is very rare, Neoplastic involvement of the pericardium may result in rapidly developing hemorrhagic effusion. A 30-year-old male who occasionally suffered from chest tightness was referred to our hospital under the diagnosis of unstable angina. He presented with acute chest pain and severe dyspnea that had developed one day previously. The diagnostic investigations such as echocardiography, chest CT and magnetic resonance image suggested cardiac tamponade that was caused by rupture of the pericardial teratoma. An operation to remove the tumor and effusion was performed. The pericardial mass was completely excised, and the result of the frozen biopsy favored malignancy. The final pathologic report was malignant fibrosarcoma of the pericardium and no malignant cells were found on the cytology of the pericardial effusion. The patient had a smooth postoperative course and was referred to another hospital for additional radiation therapy. We report here on this case of cardiac tamponade that was caused by primary pericardial fibrosarcoma, and this required urgent diagnosis and surgical management.

The clinical manifestation of pericardial disease is similar to that of coronary artery disease and aortic disease. Therefore, a timely and accurate diagnosis is necessary. The pericardium is a 2-layered membrane that envelops the heart and great vessels, and there are numerous anatomic variations and pathologic conditions. Large or unusually located pericardial recesses can be easily mistaken for abnormal findings. Additionally, primary pericardial diseases resulting from infections, tumors, and injuries are possible; further, diseases can quickly spread along the pericardium. Echocardiography is generally the first imaging tool used to evaluate the pericardium. However, it has limited windows and poor resolution. Besides, the evaluation of postoperative echocardiography is sometimes limited. Currently, CT and MR imaging are useful for evaluating pericardial diseases. Detailed knowledge of the pericardium is important for interpreting the images and clinical results.
