Lymphangioleiomyomatosis (LAM) is a rare and slowly progressive disorder that usually arises in the lung, affects exclusively women in their childbearing years, and typically presents with progressive dyspnea on exertion and pneumothorax. Infrequently, extra-pulmonary LAM can occur in the retroperitoneum, uterine wall, mediastinum and intraperitoneal lymph nodes. Histologically, LAM is characterized by a proliferation of perivascular epithelioid cells (PEC) that express markers for both melanocytes and smooth muscle cells...

Sclerosing mediastinitis (SM) is an aggressive fibroproliferative process in the mediastinum that may lead to encasement of mediastinal structures within a dense fibrotic mass. This disease may cause significant clinical complications, morbidity, and even mortality. The etiology and pathogenesis of SM is unclear and in more than one third of cases remains idiopathic. Among the known causes of SM, granulomatous infection is the commonest. Association of SM with radiation therapy has been rarely reported. Herein, we are reporting a case of postradiation sclerosing mediastinitis diagnosed in fine needle aspiration (FNA) specimen...

A previously healthy man, who had undergone coronary artery bypass 10 years earlier and had been diagnosed with brucellosis due to Brucella septicemia after Brucella arthritis, presented with chest pain and high fever. Anti- Brucella antibiotics were started, but after 4 weeks, his high fever remained. An infected mass was confirmed by computed tomography, and surgical intervention was performed via a median sternotomy. A large amount of thick pus gushed from an abscess in the upper mediastinum. The abscess cavity had a thick granulation wall, and cultured pus was positive for Brucella only...

Thymic carcinoma is a rare cancer, accounting for only 1% to 4% of thymic epithelial tumors. Endobronchial metastasis is a rare presentation of these tumors. A 64-year-old man presented with a cough. Lung cancer was suspected because a chest radiograph showed a 7-cm mass in the left pulmonary hilum. Computed tomography showed a mass in the anterior mediastinum and an infiltrate in the upper lobe of the left lung. Bronchoscopy demonstrated bilateral polypoid tumors in the left B bronchus and the right B bronchus...

The Life Span Study (LSS) of Japanese atomic bomb survivors is comprised of a large, population-based cohort offering one of the best opportunities to study the relationship between exposure to radiation and incidence of respiratory cancers. Risks of lung, laryngeal and other cancers of the respiratory system were evaluated among 105,444 LSS subjects followed from 1958 to 2009. During this period, we identified 2,446 lung, 180 laryngeal and 115 other respiratory (trachea, mediastinum and other ill-defined sites) first primary incident cancer cases...

We report a 53-year-old man with metastases of alveolar soft-part sarcoma originated from the mediastinum. He was hospitalized due to lower extremities' paralysis. Computed tomography scan findings revealed multiple nodules of bilateral lungs, swollen mediastinal lymph nodes, and osteolysis of thoracic vertebrae. We performed spinal decompression and biopsy from vertebra. And, we finally diagnosed this case as metastases of mediastinal alveolar soft-part sarcoma which was removed 10 years ago. Alveolar soft-part sarcoma is rare tumor accounted for 0...

Gastrointestinal stromal tumors (GISTs) are the most common type of gastrointestinal mesenchymal tumors, although metastasis to the perigastric lymph nodes is relatively rare, compared with liver or peritoneal metastasis. In this report, we describe a case of stomach GIST with a solitary simultaneous metastasis in the left axillary lymph node. A 68-year-old man was diagnosed with a large upper-stomach GIST, and computed tomography and positron emission tomography revealed masses in the left axilla and right mediastinum...

BACKGROUND: To examine whether combined use of (123)I-FP-CIT dopamine transporter single photon emission computed tomography (DAT-SPECT) and (123)I-MIBG myocardial scintigraphy (MIBG) is superior to either modality alone for diagnosing Parkinson's disease (PD). METHODS: Patients with probable PD (n=120) who underwent both DAT-SPECT and MIBG myocardial scintigraphy within short intervals were enrolled. Specific binding ratio (SBR) of DAT-SPECT images and heart-to-mediastinum (H/M) ratio of MIBG images were used as quantitative measures...

Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully recovered after eight days of conservative treatment. The cause of this case was the penetration of high-pressure air through the gingival sulcus, which had a weakened gingival attachment...
