Cutaneous calcinosis, also calcinosis cutis and cutaneous calcification, is calcification of the skin. It is benign in itself; however, the underlying cause may not be.
General
- Benign in itself; underlying cause may not be benign.
- May be a scrotal lesion - known as scrotal calcinosis.[1]
Subtypes:[2]
- Dystrophic - due to death of cells; may be related to a tumour.
- Metastatic - due to chronic renal failure; hyperkalemia; paraneoplastic phenomenon.
- Iatrogenic - post surgical.
- Idiopathic.
Gross
- Firm nodule.
Microscopic
Features:
- Dermal calcification:
- Acellular purple blobs on H&E.
- +/-Artefactual tearing of surrounding tissue due to processing (cutting).
- +/-Small artefactual lines ~1-2 micrometers due to processing (cutting).
- +/-Greyish rim of paucicellular material.
- Usu. well-circumscribed.
- May be surrounded by a palisading granuloma & giant cells.
- Acellular purple blobs on H&E.

The sections show subcutaneous calcifications surrounded by macrophages and giant cells. No nuclear atypia is apparent. The overlying skin is unremarkable.
