Cloaked up osteosarcoma: chondroblastoma-like osteosarcoma — a case report and literature review

Sivaranjani Selvaraj1, Prashanth Jayapal2, Suma Mysore Narayana1, Champaka Gopal1

Abstract

Osteosarcoma (OS) is the most common nonhematopoietic bone malignancy. Chondroblastoma-like osteosarcoma is an extremely uncommon variant with only 26 cases reported in medical literature in English. Given its rarity, diagnosis and management can be challenging. Osteosarcoma patients frequently receive inadequate care and incorrect diagnoses, which can lead to recurrences. Hereby, we report a rare case of osteosarcoma in an untypical location with a review of the literature. The case of an 18-year-old male with chondroblastoma-like osteosarcoma in the body of the sternum highlights diagnostic pitfalls and emphasizes the importance of morphology.
