ABSTRACT
We describe the case of a 72-year old male with pleural effusion associated with prostate cancer. There was a previous history of tobacco smoking (pack/year 47) and of total prostatectomy followed by external beam radiation therapy seven years previously for prostate cancer. Furthermore, he was submitted to orchiectomy plus non-steroidal anti-androgen blockage, in addition to docetaxel-based chemotherapy and prednisone. After the beginning of chemotherapy, a progressive elevation in prostate specific antigen (PSA) levels was observed. On admission, he presented with fever, weight loss, and respiratory symptoms due to a massive right pleural effusion. Fluid samples obtained by needle aspiration showed haemorrhagic exudates without malignant cells. Pleural metastasis were detected by thorax imaging studies, and biopsy samples revealed prostate adenocarcinoma as the origin of his pleural effusion. Pleural fluid was drained and talc pleurodesis was performed. This report aims to describe the occurrence of massive pleural effusion due to metastasis of prostate cancer, and emphasizes the role of pleural biopsy with immunohistochemical studies to characterize this diagnosis.
RESUMEN
Se describe un hombre de 72 años con efusión pleural asociada con cáncer de próstata. Había antecedentes de tabaquismo (47 paquetes por año) así como una historia de prostatectomía radical, seguida por terapia de radiación externa, siete años antes. Además, se le sometió a orquiectomía junto con bloqueo antiandrogénico no esteroideo, además de quimioterapia a base de docetaxel y prednisona. Después de iniciada la quimioterapia, se observó una elevación progresiva en los niveles de PSA. En el momento del ingreso, el paciente presentaba fiebre, pérdida de peso, y síntomas respiratorios debidos a una efusión pleural derecha voluminosa. Las muestras de fluido obtenidas mediante punción aspirativa con aguja fina, mostraron exudados hemorrágicos sin células malignas. Se detectaron implantes pleurales con los estudios imaginológicos del tórax, y las muestras de la biopsia revelaron que el origen de su efusión pleural, era un adenocarcinoma de la próstata. Se drenó el fluido pleural, y se procedió a practicar una pleurodesis con talco. Este reporte tiene por objetivo describir la ocurrencia de la efusión pleural masiva debido a la metástasis del cáncer de la próstata, y enfatiza el papel que desempeña la biopsia pleural junto a los estudios inmunohistoquímicos a la hora de caracterizar este diagnóstico.
