title: Calcinosis cutis following contact with calcium chloride solution.
abstract: Calcinosis cutis is the deposition of insoluble calcium in the cutaneous tissue. Calcinosis cutis can be classified as metastatic, dystrophic, idiopathic or exogenous. We report a 48-year-old white man who was dismantling a portable ice skating rink when calcium chloride solution from the pipes spilt onto his clothing. Several days later, he started to develop mildly pruritic erythematous papules, some studded with white deposits and some with umbilication over the exposed areas corresponding to the spillage of the calcium chloride solution. Histological features revealed interstitial fibrohistiocytic reaction with calcium-encrusted degenerated collagen bundles in the dermis which was further confirmed by von Kossa stain. He was commenced on topical corticosteroid cream twice daily and the lesions cleared completely between 6 to 10 weeks.
