What causes blackish pleural effusion?
Disease description:
My grandfather has long suffered from pleural effusion. Yesterday, when the fluid was drawn, it was found to be ink-black. What does it mean if pleural effusion is ink-black?

Blackish discoloration of pleural effusion may result from Aspergillus niger invading the fluid, causing the pleural accumulation to appear black. It could also be due to melanoma or lung cancer. Black pleural effusion leading to pleural fluid accumulation requires surgical removal of the lesion, and treatment should be conducted at a正规 medical facility.
