Calcifying aponeurotic fibroma is a rare benign tumor found primarily on the hands or wrists of children and adolescents. It has a tendency of local invasion, and a high recurrence rate after excision. An 11-year-old boy had a hard indurated. 3 x 3cm-sized, nodule on the right sole for 3 years. A biopsy specimen showed heavy focal calcification within areas of densely paked stromal fibroblastic cells. Some fields contained multinucleatec giant cells and chondroid metaplasia. There were infiltrative growth patterns of fibroblastic cells extending into the adjacent adipose tisse and blood vessels. There was no evidence of reccurence at 3 months after the operation.
