Calcaneal Osteosarcoma: A Rare Instance in Adolescent Patient

INTRODUCTION: Calcaneal osteosarcoma is extremely uncommon, accounting for <1% of all osteosarcomas. They typically exhibit swelling and chronic heel pain and are frequently clinically misdiagnosed as traumatic or inflammatory process. CASE REPORT: We report a case of a 19-year-old girl with calcaneal osteosarcoma who initially complained of heel pain that was refractory to analgesic medications over a period of 4 months. CONCLUSION: The case highlights the importance of early diagnosis and management of osteosarcoma in patients with chronic heel pain and also highlights the importance of considering osteosarcoma as a differential diagnosis in adolescents who present with chronic heel pain, despite the rarity of the condition.
