Background: Pulmonary carcinoids (PCs) are rare tumors that account for <2% of all lung cancer cases. Patients who undergo resection PC generally have a favorable prognosis, but there is risk late recurrence and distant metastasis. The objective this study was to identify biomarkers using RNA sequencing immunohistochemistry.

BACKGROUND Treatment of pulmonary metastasis from urothelial cell carcinoma has been mostly palliative chemotherapy and the role of pulmonary metastasectomy has not been investigated much. MATERIALS AND METHODS This study is a retrospective interim review of pulmonary metastasectomy from urothelial carcinoma at single institution between 1998 and 2010. Overall 16 patients underwent pulmonary ...

Angiosarcoma is a rare malignant vascular tumor. Pulmonary involvement is usually attributable to metastasis from other primary sites, primary pulmonary angiosarcoma therefore being quite uncommon. We report a case of angiosarcoma with pulmonary involvement, probably primary to the lung, which had gone untreated for more than two years. We describe this rare neoplasm and its growth, as well as ...

Primary pulmonary meningiomas represent a rare tumor entity. Few cases have been reported in the English medical literature, and they have almost all been solitary and benign in nature, with the exception of several extremely rare cases. We report herein a case of PPM that raised suspicion of a pulmonary metastatic tumor initially, as it was depicted as a single, round, small, ground-glass opac...

INTRODUCTION Tumor rupture and pulmonary metastasis in patients with hepatocellular carcinoma are both associated with poor prognosis and treatment strategies are controversial. CASE PRESENTATION Here we report a 50-year-old man with survival of over 90 months after undergoing an extended right lobectomy for a ruptured hepatocellular carcinoma and then repeated resections for pulmonary metast...
