Diagnostic Considerations

Many systemic conditions are associated with cutaneous calcification, and many of them may secondarily ossify. Consider the following:

  • Dystrophic calcification (eg, scleroderma; calcinosis cutis, Raynaud phenomenon, esophageal motility disorder, sclerodactyly, and telangiectasia [CREST] syndrome; panniculitis; Ehlers-Danlos syndrome; Werner syndrome; some cutaneous neoplasms; after traumatization)

  • Metastatic calcification [26]

  • Iatrogenic calcification (as a complication of intravenous calcium chloride and calcium gluconate therapy)

A special concern is recognizing classic clinical features of fibrodysplasia ossificans progressiva prior to the appearance of heterotopic ossification, avoiding surgical interventions that may lead to irreversible iatrogenic harm. [27]
