| Summary: | 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. SIMILAR CASES PUBLISHED: 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 |
