Tumoral calcinosis in two infants.

Tumoral calcinosis (TC) is an uncommon disease, characterized by deposits of large, calcified painless soft-tissue masses around major joints in otherwise healthy children and young adults. This condition is a rare inherited metabolic disorder of unknown etiology. Biochemical findings are normal except for its occasional association with hyperphosphatemia. The youngest occurrence reported in the literature on TC may be one case of a five-month-old boy. The authors report here on two younger infants with TC, one aged ten days and the other aged three months, who were followed for more than three years and observed to completely recover all motorskeletal functions.
