Really interesting answer from Draven616... that the Irish for black man is: fearr gorm (literally blue man)... I'm of half Irish & half Italian descent, and there is a common expression for the black people that sounds like Mulin-yon...
One theory is that Vitamin D toxicity can lead to calcium deposits appearing. Vitamin D toxicity is a condition that arises when too much vitamin D is consumed.
Treatment of calcium deposits in the lungs is usually designed to treat the underlying cause of the calcium deposits. For instance, patients who have ossification of the lung cartilage or pulmonary granulomas from sarcoidosis may be given steroids to help break up the calcium deposits in the lungs.
