Clinical InformationClinical

  • Calcinosis Cutis

    pathological deposition of calcium in the skin and subcutaneous tissue. excessive calcification of the skin may be associated with underlying diseases that cause tissue damage (e.g., ehlers-danlos syndrome; pseudoxanthoma elasticum; rothmund-thomson syndrome; and werner syndrome) or that cause abnormal calcium and phosphate metabolism (e.g., calciphylaxis; chronic kidney failure; hyperparathyroidism; and sarcoidosis).

  • Hyperphosphatemic Familial Tumoral Calcinosis

    an autosomal recessive disorder caused by loss-of-function mutation(s) in the galnt3, fgf23, or kl gene, which encode polypeptide n-acetylgalactosaminyltransferase 3, fibroblast growth factor 23, and klotho, respectively. this condition, the biochemical hallmark of which is hyperphosphatemia caused by increased renal phosphate absorption, is characterized by the progressive deposition of calcium phosphate crystals in periarticular spaces, soft tissues, and/or bone.
