Background: Extraosseous Ewing sarcoma (EES) usually has a pseudocapsule and high vascularity, making it well circumscribed and focally dense with contrast enhancement on magnetic resonance imaging (MRI). Consequently, it is difficult to
BACKGROUND
SMARCA4-deficient thoracic sarcoma is a recently proposed entity of soft tissue tumors associated with an extremely poor prognosis. Its cytologic features have not been well described in the literature yet.
METHODS
A woman in her early 30s who presented with chest pain was found to have a
Pulmonary artery sarcomas (PAS's) are extremely rare malignant tumors that arise from the endothelial lining of the pulmonary arteries. On CT scans PAS's appear as intraluminal filling defects in the pulmonary arteries, mimicking pulmonary embolism (PE). Due to the similarities in radiographic
OBJECTIVE
To improve our understanding and facilitate early diagnosis of pulmonary artery sarcoma (PAS).
METHODS
The clinical and radiological features of 9 histopathologically confirmed patients with PAS were retrospectively analyzed.
RESULTS
Our PAS cohort consisted of 5 males and 4 females, with
BACKGROUND
A 40-year-old woman presented with dyspnea in the fifth month of pregnancy followed by a sudden onset of pleuritic chest pain 2 weeks postpartum. She was diagnosed as having pulmonary embolism by CT angiography and anticoagulated with heparin followed by warfarin. Despite 6 months of
Primary mediastinal synovial sarcomas are exceedingly uncommon tumors. Herein, we present the case of primary mediastinal synovial sarcoma (monophasic spindle cell-shaped variant) fully occupying the right hemithorax in a 37-year-old woman who presented to clinic with a 2-month history of
A 36-year-old man presented with a pleural tumor. The first pathologic analysis diagnosed biphasic pleural malignant mesothelioma. However, the atypical clinical course, the early development of lung metastases and a new reading of histologic documents led to the diagnosis of primary pleural
Primary pleuropulmonary synovial sarcomas are rare soft tissue malignancies; combined metastatic involvement of the heart is extremely rare. In this case report, a 17-year-old female presented with a history of chest pain. Chest radiographs revealed a round mass in the left upper hemithorax, and
Synovial sarcoma is a malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. Synovial sarcoma arising from the chest wall is rare and only some cases had been reported in the literature. We present a 57-year-old woman who presented with chest pain. Radiologic
Circumscribed solid nodules are common in pulmonary metastases from sarcoma, but cystic pulmonary metastases from sarcomas are extremely rare. An unusual case of a 33-year-old man presenting with left spontaneous pneumothorax in association with cystic pulmonary metastases from an epithelioid
BACKGROUND
Pulmonary sarcomas overall are very uncommon and comprise only 0.5 % of all primary lung malignancies. The diagnosis is established only after sarcoma-like primary lung malignancies and a metastatic extrathoracic sarcoma have been excluded. Synovial sarcoma accounts for ~8 % of
Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular
Malignancy of the pericardium is a very rare entity. We describe here a case of a 38-year-old male admitted because of chest pain and shortness of breath. Following magnetic resonance imaging and CT-guided biopsy of the mediastinal mass, spindle cell sarcoma of the pericardium was diagnosed. The
Pleuropulmonary synovial sarcoma (PPSS) is increasingly recognized as a subtype of sarcoma because of the recent identification of a distinctive chromosomal translocation specific to synovial sarcoma. Soft-tissue synovial sarcoma is far more common than PPSS and typically develops in para-articular
We present an unusual association of mediastinal germ cell tumor containing seminoma and angiosarcoma components and splenic histiocytic sarcoma. A 15-year-old boy presented with chest pain. Histopathologically, an anterior mediastinal mass contained typical seminoma, immature teratoma, embryonal
