Subperiosteal hematoma as a rare complication of neurofibromatosis 1: A case report and review of the literature.

INTRODUCTION

Subperiosteal hematoma (SPH) is a rare complication of neurofibromatosis type 1 (NF-1) which can be presented spontaneously or after a minor trauma a painful or painless growing lesion.

PRESENTATION OF CASE

Here, we presented a 10-year-old boy, a known case of NF-1, who presented with a painless growing leg lesion. The bony wall cystic lesion was suggested based on radiologic and pathologic investigation. During the operation, an SPH was detected and excised completely.

DISCUSSION

Consistent with previous reports, our case of subperiosteal hematoma in an NF-1 patient predominantly presented with well-established subperiosteal bone proliferation on plain radiographs, with the hematoma most commonly affecting the tibia.

CONCLUSION

The SPH in NF-1 and differentiating it from a malignant transformation should be considered for the rapidly enlarging bony mass.
