Tumoral calcinosis: a case report and review of the literature.

Tumoral calcinosis is an uncommon and seemingly unrecognised disease of obscure aetiology. A case in a young Caucasian boy aged 14 is reported. The characteristic clinical features, radiological and pathological findings are described. The condition must be differentiated from other varieties of pathological calcification such as chronic vitamin D intoxication, the milk-alkali syndrome, chronic nephritis, primary hyperparathyroidism, calcinosis universalis, calcinosis circumscripta and dystrophic calcification.
