A thymoma commonly occurs in the superior mediastinum or the upper part of the anterior mediastinum but can be located in other places in rare cases. Cystic degeneration in a thymoma is a relatively common but focal event. In rare cases, the process proceeds to the extent that most if not all of the lesion becomes cystic. We report a case of a patient with a paracardial cystic thymoma in the lower aspect of the anterior mediastinum. A 49-year-old woman was referred to our hospital because of a mass discovered incidentally on a chest X-ray. She showed no symptoms or signs. Contrast-enhanced chest CT scan revealed a 5x5cm sized, well-marginated, right paracardial cystic mass with a curvilinear and oval enhancing solid portion. A Surgical resection was performed. The mass was discontinuous with normal thymic tissue. Microscopy revealed a type B1 thymoma with prominent foci of medullary differentiation according to the WHO classification. There was no capsular or local invasion. The postoperative course was uneventful and the patient was discharged in good health. (Tuberc Respir Dis 2007; 62: 331-335)

Endobronchial leiomyoma is a rare tumor that accounts for less than 2% of pulmonary benign tumors. A 32 year-old woman was admitted with fever, cough and sputum for a month. She had suffered from intermittent cough over three years. The chest X-ray and chest CT(computed tomography) showed a nodular lesion obstructing the proximal portion of the left lower lobar bronchus and atelectasis of the left lower lobe. Flexible Bronchoscopy detected a mass obstructing the distal portion of the left main bronchus and endobronchial biopsy showed benign smooth muscle cells. There was no abnormal finding in the uterine examination. Therefore this case was diagnosed as primary endobronchial leiomyoma. The lobectomy was performed due to intractable pneumonia and secondary parenchymal destruction. Postoperative course was uneventful and she was discharged in good health.
