While renal cell carcinoma frequently metastasizes to the lung, solitary pleural metastasis without lung involvement is extremely rare. A 69-year-old man was admitted to our hospital with a solitary pleural metastasis 6 years after surgery for renal cell carcinoma. Needle biopsy was performed, and the tumor was diagnosed as a metastasis of renal cell carcinoma. The pleural tumor was surgically resected. The patient received interferon-α as postoperative therapy. He has been alive for 9 years without recurrence. Only 11 cases of solitary pleural metastasis have been reported thus far, and of these, 7 involved a large amount of pleural effusion resulting in a poor prognosis. This is the first reported case of solitary pleural metastasis from renal cell carcinoma, which was curatively resected, as indicated by long-term survival.

Primary solitary fibrous tumor of the stomach: A case report and a review of literature.
Medicine (Baltimore)

Rationale: Solitary fibrous tumors (SFTs) are spindle cell tumors that typically occur in the pleura and peritoneum, but very rarely in the stomach. To our best knowledge, there are only 10 cases reported in English literature. We reported a case of primary stomach SFT and summarized the characteristics of all previous cases, suggesting that pathologists and surgeons should include this disease in the differential diagnosis list of primary mesenchymal tumor of the stomach.

Background: CT-guided trans-thoracic lung biopsy (CT-TTLB) is efficient and widely used to diagnose pulmonary nodules. After pneumothorax, the second most frequent complication is hemoptysis, which can be life-threatening. These patients often have comorbidities and are on acetylsalicylic-acid (ASA) therapy.

Solitary fibrous tumors are rare and typically benign fibroblastic neoplasms with a mean age of onset ranging from 60 to 70 years. Solitary fibrous tumors may arise anywhere within the body, however the pleura is the most common site of origin for these tumors, with approximately 30% of tumors arising from the pleura. In this report we highlight the case of a 62-year-old woman who presented with gradually progressive left sided chest pain that was eventually diagnosed as a pleural SFT.

Pleural tuberculoma is often observed during treatment for tuberculous pleurisy; however, this condition is rarely found as a solitary pleural nodule in patients without a history of tuberculosis treatment, and no cases have been reported in children. We report a case of a 12-year-old boy with pleural tuberculoma presenting as a solitary mass. He had a fever and cough that prompted chest radiography, which revealed a mass in the right lung.
