Abstract
Various etiologies contribute to the development of pleural effusion, although differentiating these causes can be challenging in some cases, especially in patients who have inconsistence clinical and laboratory evidence. We present a 79-year-old female patient with massive right sided pleural effusion along with an air-fluid level and pleural thickening in chest X-ray. In the thoracentesis, the patient had pleural effusion with neutrophil predominance, and in the preliminary pathological examination of the thoracoscopic biopsy of the pleura, severe chronic inflammation with fibrous thickening and mesothelial hyperplasia was reported. Finally, a re-examination of the pathology revealed a final diagnosis of pleural epithelioid hemangioendothelioma, a tumor of vascular origin uncommonly seen in the thorax.
