'''Cutaneous calcinosis''', also '''calcinosis cutis''', is calcification of the [[skin]]. It is benign in itself; however, the underlying cause not be. | |||
==General== | |||
*Benign in itself; underlying cause may not be benign. | |||
*May be a [[scrotum|scrotal]] lesion - known as ''scrotal calcinosis''.<ref name=pmid20178701>{{Cite journal | last1 = Dubey | first1 = S. | last2 = Sharma | first2 = R. | last3 = Maheshwari | first3 = V. | title = Scrotal calcinosis: idiopathic or dystrophic? | journal = Dermatol Online J | volume = 16 | issue = 2 | pages = 5 | month = | year = 2010 | doi = | PMID = 20178701 }}</ref> | |||

#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. | |||
