• mediastinal synovial sarcoma
  26 March 2018

  Definition: Synovial sarcoma (SS) is a translocation-associated sarcoma characterized by SS18-SSX1/2 fusion. It presents most often in the extremities of young adults. While SS regularly occurs in the pleuropulmonary parenchyma, the mediastinum is an exceedingly rare primary site.
  Mediastinal SS is a rare and aggressive malignancy most common in patients younger than 50 years. Most are monophasic and reach large size before detection. Poorly differentiated morphology is common.
  SS should (...)

• mediastinal low-grade extraskeletal osteosarcoma
  19 March 2018

  Low-grade extraskeletal osteosarcoma of the mediastinum; mediastinal LGESOS
  Definition: Extraskeletal osteosarcoma (ESOS) is a rare soft tissue sarcoma, typically characterized by a bone-producing neoplasm. Low-grade extraskeletal osteosarcoma (LGESOS) is an extremely rare soft tissue tumor, and patients with LGESOS tend to have a better prognosis.

• mediastinal pericytic tumors
  18 March 2018

  mediastinal perivascular tumors
  Less than ten cases of glomus tumour, including a single malignant variant, have been described in the mediastinum until 2015. All cases were located in the posterior or superior compartments of the mediastinum in young or middle-aged females. The single malignant case, which resulted in this patient’s death, occurred in a 74-year-old female.
  Pain and dyspnea or cough were presenting symptoms. All benign cases were successfully treated by surgery without (...)

• mediastinal leiomyosarcoma
  18 March 2018

  Definition: Mediastinal leiomyosarcoma is a very rare tumour with less than 40 cases until 2015.
  Mediastinal leiomyosarcoma occurs in adult patients (26–88 years) of either sex.
  A disproportionate number of cases arise in the posterior mediastinum, where tumours are often clinically asymptomatic.
  Resected tumours measured up to 18 cm, often without clear relationship to neighbouring anatomic structures. In some cases, an origin from major vessels seemed likely, whilst in others, major (...)

• mediastinal leiomyoma
  18 March 2018

  Definition: A mediastinal leiomyoma is a leiomyoma arising in the mediastinum.
  To qualify as a primary mediastinal leiomyoma, tumours should arise from the somatic soft tissue of the mediastinum, whilst esophageal and large vessel primaries should be excluded.
  If these criteria are applied, primary mediastinal leiomyoma is very rare with approximately 20 reported cases in the literature in 2015.
  Mediastinal leiomyoma is twice as common in females as in males and is mainly seen in the (...)

• mediastinal tumors

  Definition: Mediastinal tumors are tumors arising in the mediastinum.
  The mediastinum is the cavity that separates the lungs from the rest of the chest. It contains the heart, esophagus, trachea, thymus, and aorta. The mediastinum has three main parts: the anterior mediastinum (front), the middle mediastinum, and the posterior mediastinum (back).
  The most common mediastinal masses are neurogenic tumors (20% of mediastinal tumors), usually found in the posterior mediastinum , (...)

• mediastinal smooth muscle tumors
  18 March 2018

  Definition: Mediastinal smooth muscle tumors are smooth muscle tumors arising in the mediastinum.
  Smooth muscle cell tumours resemble normal smooth muscle and retain many of their immunohistochemical markers. Fewer benign smooth muscle cell tumours (leiomyomas) than malignant smooth muscle tumours (leiomyosarcomas) have been reported in the mediastinum.

• mediastinal extramedullary hematopoietic tumor
  16 September 2013

  mediastinal reactive extramedullary hematopoietic tumors; thoracic extramedullary hematopoiesis
  "Reactive extramedullary hematopoietic tumors that usually occur in patients with severe chronic anemias.
  Patients with extramedullary hematopoietic tumors are characterized by anemia, frequent hepatosplenomegaly and abnormal peripheral blood smears, and may be any age.
  The tumors are usually multiple and usually located in the mediastinum or epidural space.
