Increased densities and calcifications in the finger bones of children.

A feature of irregular calcifications and increased densities in the metaphyseal region of the fingers of the hand in adolescent children, occurring mostly in males, is described. These changes become evident at puberty and disappear with the closure of the epiphyses. The etiology of this feature does not appear to be related to a specific hormone. It may be the result of an imbalance between those hormones which cause the pubertal spurt, possibly combined with an irregularity of testosterone secretion.
