title: Rapid recurrence of calcifying fibrous pseudotumor (a case report).
abstract: Calcifying fibrous pseudotumor is a benign tumor-like lesion characterized by the presence of a whorl bundle of collagen fiber with deposit calcification and infiltration of inflammatory cells. This lesion is reportedly rare and involves subcutaneous or deep soft tissue in the extremities, trunk, neck and so on. This tumor has low recurrence even if only simple excision or enucleation is performed. We report a case of calcifying fibrous pseudotumor arising in the nuchal lesion of an 8-year-old boy who had a local recurrence 18 months after a simple excision had been performed. The patient had no evidence of recurrence or metastasis 10 months after the second operation.
