| O'Brien WM, La Du BN, Bunim JJ Biochemical, pathologic and clinical aspects of alkaptonuria, ochronosis and ochronotic arthropathy. |
|
| Other important consequences of alcaptonuric ochronosis are aortic valve stenosis and urinary tract involvement. |
|
| As a result, a black pigment, called ochronosis, forms and binds to bone, cartilage and skin. |
|
| There are dermatological problems such as striae atrophica, colloid milium ochronosis, scabies, cutaneous atrophy and pitch black pigmentation. |
|
| Using them without consulting a doctor can result in hyperpigmentation or ochronosis, a bluish black discolouration of the skin. |
|
| Prolonged use of this ingredient thickens collagen fibers, resulting in ochronosis. |
|
| Among the possible causes of black thyroid are minocycline-induced pigmentation, hemochromatosis, ochronosis, mucoviscidosis, ceroid storage disease, bruising, and hemorrhage. |
|
| Ochronosis is a rare metabolic disorder that is characterized by a brownish-black pigmentation of connective tissues. |
|
| Ochronosis is usually seen in darker skin tones when hydroquinone is used in high concentrations or if a low concentration is used for extended time periods. |
