this study was undertaken to examine the ability of spect in differentiation of a pulmonary lesion suspecions of lung cancr. a total of 170 patients with suspected lung cancer were studied. a dose of tl-201 chloride {148-296 mbq) was injected intravenously and tomographic early and delayed scans were obtained at 15 miniutes and 3 hours post injection, respectively. delayed tl-201 spect visulize...

pleuropulmonary blastoma (ppb) is a rare, malignant intrathoracic tumor that occurs mostly in children before 5 years old. it consists about 15% of all primary pediatric pulmonary tumors and shows various mesenchymal components. its presentations are nonspecific and common symptoms include fever, cough, chest pain, respiratory distress, and pulmonary infection. ppb should be considered in the d...

results: among 11 patients who underwent surgery consisted of eight males and three females. their metastasis originated from testis tumors (n = 5), renal cell carcinoma (rcc; n = 4), bladder tumor (n = 1), and prostate cancer (n = 1). their mean age was 41.27 years (range, 21-67). the mean age of the patients with rcc and testis tumor at the time of diagnosing metastasis was 54 and 24.8 years,...

Pulmonary granular cells tumors (CGT) are rare tumors, that derive from Schwann cells. In the tracheobronchial and pulmonary tree, they remain a diagnostic challenge. There no well-established criteria to differentiate between benign, atypical, malignant GCT. Moreover, its real frequency in respiratory tract is still unknown. Here, we represent 2 cases of bronchial lung GCTs. We aim highlight a...

We describe a case of pulmonary blastoma, a rare primary lung malignancy which affects a younger population. This tumor contains both mesenchymal and epithelial elements. Pulmonary blastoma tends to relapse locally and metastasizes mainly in the first few years. It has a poor 5-year prognosis, and shows a potentid radio-chemosensitivity. Because these tumors are considered malignant, surgic...
