Oral presentation of metastatic calcinosis cutis.

An 80-year-old man presented with a hard swelling in the lower labial sulcus. Radiological investigation showed a mineralized mass on the labial aspect of an edentulous mandible which on excision, demonstrated the histological features of calcinosis cutis. No other sites seemed to be affected by calcific deposits in this patient, who appears to be the oldest reported case of metastatic calcinosis, and the first intra-oral case, to date. The different forms of calcinosis cutis are highlighted.
