Patient Data

Age: Young child

Nodular prominence of the costochondral junctions bilaterally.

Case Discussion

Prominence of the costochondral junction can be seen in a number of conditions:

  • rickets: Nodularity at costochondral junction (rachitic rosary)
  • scurvy: The costochondral junction is more angular and has a sharper step-off (scorbutic rosary). The sternum is usually found to be depressed.
  • chondrodystrophy

Appearances in this case most likely represent rickets.
