Patients excrete large amounts of homogentisic acid in their urine and a black ochronotic pigment is deposited in their cartilage and collagenous tissues. Ochronosis is the predominant clinical complication of the disease leading to ochronotic arthropathy, dark urine, pigment changes of the skin, and other clinical features.
