Malignant Pleural Effusion Secondary to Clear cell Renal Cell Carcinoma- A Case Report

Abstract

Renal cell carcinoma is the most common renal neoplasm. Its presentation is often very occult, and it may be discovered incidentally. It may present with the classic symptoms of back pain, flank pain, hematuria, or hypertension. Renal cell carcinoma may also present with malignant pleural effusion at diagnosis; however, it is very rare. Pleural effusion secondary to renal cell carcinoma constitutes only about 1% to 2% of all malignant pleural effusions. We report a case of 55-year-female who was a known case of Right side Renal cell carcinoma post operated and on chemotherapy suddenly presented in emergency department with breathlessness and chest pain. Chest X-ray demonstrated right-sided moderate pleural effusion; computed tomography (CT) reported bilateral effusion in the pleural cavity. CT-guided pleural thoracocentesis   was performed. Cytology and cell block morphology showed clear cell type malignant tumor, leading to diagnosis of clear cell carcinoma in pleural fluid secondary to clear cell renal cell carcinoma. The study aim to discuss the Malignant pleural effusion secondary to Clear cell Renal cell carcinoma.
