Renal Clear Cell Carcinoma Discovered Following Pyothorax: A Case Report
Abstract
Renal cell carcinoma (RCC) is known for its heterogeneous clinical presentation and its potential for atypical metastatic spread. Thoracic manifestations are usually related to pulmonary or pleural metastases; however, presentation as pyothorax is exceedingly rare. We report the case of a patient in whom clear cell RCC was incidentally discovered during the etiological workup of a pyothorax. This case highlights the diagnostic challenges associated with unusual presentations of RCC and emphasizes the importance of thorough etiological investigation in pleural infections with atypical features.
