Xanthogranulomatous pleuritis induced by recurrent biliothorax due to a biliopleural fistula: The first case report in the literature

Abstract

Xanthogranulomatous pleuritis is an extremely rare pathological entity, characterized by the infiltration of foamy cells and multinucleated giant cells within the pleural space. This condition often mimics infectious and neoplastic processes, presenting significant diagnostic challenges. This report details the first documented case of xanthogranulomatous pleuritis induced by recurrent biliothorax due to a biliopleural fistula, presenting a unique clinical scenario. We describe the clinical presentation, diagnostic hurdles, and both the surgical and medical management of this case. The discovery of biliothorax, evidenced by pleural fluid bilirubin levels that exceed serum bilirubin levels, underscores the importance of considering biliothorax in the differential diagnosis of recurrent pleural effusions, particularly in patients with a history of trauma. This case emphasizes the need for heightened awareness and a multidisciplinary approach in the diagnosis and treatment to effectively manage this complex condition and prevent recurrence.
