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.
