Six cases are reported in whom the diagnosis of benign pleural thickening with lung folding simulating peripheral pulmonary neoplasm was made. Three patients presented with chest pain, two were asymptomatic, and the abnormality was a chance finding in one patient with asthma. The radiographs in all cases showed similar appearances--a peripheral opacity appearing to lie within the lung, usually ...

These patients usually have non-specific clinical presentation and radiological findings. Therefore, it is important to increase awareness of this rare disease, as the correct characterization of the tumors will have therapeutic and prognostic...

The first case of association between Leydig cell testicular tumor and sarcoidosis is reported. From a review of the literature, this is the ninth case of association between a testicular tumor and Besnier's disease. Lung biopsy should always be performed in patients with testicular cancer when retroperitoneal lymph node involvement cannot be demonstrated in order to avoid unnecessary antineopl...

ing for approximately 1% of all soft tissue tumors. Angiosarcoma is a neoplasm that arises from endothelial cells and it usually originates in the small blood vessels. It can affect virtually any organ, but it most commonly develops in the skin and deep soft tissues, liver, spleen, heart and breast (1). We present here a rare case of primary angiosarcoma of the chest wall that was associated wi...

Background: Neuroectodermal Tumors (PNET) are malignant small cells neoplasm mainly occurring in children but can occur at any age. Extensive bleeding into the pleural cavity is rare In Children. Hemothorax would be compatible with a variety of congenital anomalies including sequestration, patent ductus artreiosus, and pulmonary arteriovenous malformation.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare cause of rapidly progressive dyspnea in a background of metastatic cancer. Gastric adenocarcinoma is the neoplasm most frequently associated with PTTM. Unfortunately, PTTM is difficult to identify clinically and is most commonly a postmortem diagnosis. We present the case of a woman with no previous diagnosis of cancer who presented wi...

Extramedullary hematopoiesis (EMH) occurs as a complication of hematologic disorders such as myelofibrosis, sickle cell anemia and thalassemia. The extramedullary tissue usually involves liver, spleen and lymph nodes, less frequently the chest. We present a recent case of a man with myeloproliferative neoplasm who developed pulmonary hemorrhage secondary to EMH in the lung and pulmonary artery....
