We report a 63-year-old patient with black-colored pus (pyopneumothorax) resulting from an infected pleural effusion associated with metastatic malignant melanoma of the skin. The patient was also positive for Pseudomonas, so the color was unexpected. Although rare, malignant melanoma can present as a black pleural effusion due to the presence of melanocytes in the pleural fluid. Black pleural fluid should raise the suspicion of malignant melanoma.
Nine cases of black pleural effusion due to different causes have been reported.1,2 Three cases of black pleural effusion due to metastatic malignant melanoma are published.2,6,7.
我们报告了一名63岁的患者，其因与皮肤转移性恶性黑色素瘤相关的感染性胸腔积液导致黑色脓液（脓气胸）。该患者同时感染了铜绿假单胞菌，因此这种颜色出乎意料。尽管罕见，但由于胸腔积液中存在黑素细胞，恶性黑色素瘤可表现为黑色胸腔积液。黑色胸腔积液应引起对恶性黑色素瘤的怀疑。
已报道9例因不同原因导致的黑色胸腔积液病例。1,2 已发表3例因转移性恶性黑色素瘤导致的黑色胸腔积液病例。2,6,7
