Desmoplastic Fibroma in the Distal Humerus of a 14-Year-Old Boy: A Case Report.

CASE: We present the case of a 14-year-old male who presented with a pathologic elbow fracture. Imaging demonstrated a lytic distal humerus metaphyseal lesion with a soap bubble appearance. After fracture healing, frozen sections obtained at open biopsy suggested fibrous tissue; thus, curettage and bone grafting was performed. Pathology confirmed desmoplastic fibroma. The patient experienced a recurrence 18 months later and had repeat curettage and allograft strutting. He had no evidence of re-recurrence 2 years after the second surgery.

CONCLUSIONS: Desmoplastic fibroma may mimic the presentation of many bone lesions. Recurrence is common despite curettage and bone grafting. This patient performed well without wide resection.
