Resolution of Proximal Humerus Enchondroma in a 53-Year-Old Female with Curettage and Bone Substitution: A Case Report.

INTRODUCTION

Enchondromas are benign cartilaginous tumors commonly affecting the small bones of the hand; however, proximal humeral involvement presenting with persistent pain in older adults is uncommon and may mimic low-grade chondrosarcoma.

CASE REPORT: A 53-year-old female presented with right shoulder pain and proximal humeral swelling. Radiographs, magnetic resonance imaging, and computed tomography imaging demonstrated a lobulated intramedullary cartilaginous lesion with cortical thinning and endosteal scalloping. The patient underwent curettage of the lesion, biopsy, and bone grafting using bone substitutes. Histopathological examination confirmed an enchondroma. Post-operative follow-up demonstrated satisfactory graft incorporation and symptomatic improvement.

CONCLUSION

This case highlights the importance of prompt radiological investigations, and histopathological examination is essential for accurate diagnosis, management with curettage and bone substitution, which showed good incorporation and outcome.
